Microsoft Outlook 2010, 2013 and 2016 crashes after installing Microsoft Dynamics CRM 2016 SP1 Client for outlook- KB3154952

Issue: Microsoft Outlook 2010, 2013 and 2016 crashes after installing Microsoft Dynamics CRM 2016 SP1 - KB3154952  (on-premises)

Crashes becomes a lot  more aggressive when other add-ins (especially from 3rd party) are installed for outlook. If 3rd party addin gets disabled in outlook then number of Outlook crash will reduce. While working with one such add-in we were seen Outlook crash as soon as outlook would start.

Following are the example of events that will be recorded in application event logs:

Description: The process was terminated due to an internal error in the .NET Runtime at IP 72BE5ABD (72930000) with exit code 80131506.



Cause: KB3154952 release version 08.01.0000.0359  that released in mid 2016 (close to July) had issue where Outlook will crash a lot more after Outlook Client for Microsoft Dynamics CRM 2016 would get upgraded to this release.

Solution: Microsoft seems to have re-published service pack for KB3154952 on 21st September 2016 under same version 08.01.0000.0359. However new set of downloads have newer version of Microsoft Dynamics CRM Outlook client 2016 version 08.1.0000.0371.


https://www.microsoft.com/en-us/download/details.aspx?id=52662



Basically when new setup files will be used, following that you should see version of Microsoft Dynamics CRM 2016 Outlook Client to be reported as 08.01.0000.0371 in program manager. 


Reference: Came across this page while looking for Microsoft articles that could explain why we say that difference in versions which seems to explain what others have also encountered/

Microsoft Natural Ergonomic 4000 Keyboard does not work on Windows 7

Problem description: I bought this keyboard to give some rest to my wrists. To my surprise when I connected keyboard to USB port it didn't work. I tried following:

1. Uninstalled keyboard from device manager and scanned again. It finds the keyboard and even the model of keyboard but it is unable to install drivers. 
2. Installed Mouse and Keyboard Center 2.3 64bit and it didn't help.
3. Installed IntelliType 8.2 64bit for Windows 7 which didn't work either,
4. Connected KB to another desktop and it worked which had Ubuntu on it.
5. Connected to another windows desktop and it worked.
6. Checked Microsoft forums for this keyboard that was not of much help.
7. On same machine where it does not work in Windows, it works in bios and while selecting booting options.

By this time, it was established that issue is with the drivers on my particular desktop. Then started to look for forums that were  unrelated to this keyboard but in general keyboard drivers issue, found somewhere mentioned that MS update KB2529073.

CAUSE: Windows update KB2529073 may cause this issue.

Solution:

1. Connect another keyboard and log on to machine in question.
2. Remove Windows update KB2529073.
3. Shutdown PC.
4. Swap keyboard again with Microsoft Keyboard.
5. Start PS and wait for MS Windows to start, you will realise that green light above [1] button is on this time which wasn't turned on when issue existed. Your keyboard should be good to go.

Exchange 2013 and Exchange 2010 mixed environment throws error message "The arbitration mailbox 'SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}' for the organization '' is located on a server that doesn't have Exchange 2013 installed. The arbitration mailbox must be moved to an Exchange 2013 server before you can enable auditing."

Issue: While enabling auditing or trying to access audit info following warning message would appear:

The arbitration mailbox 'SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}' for the organization '' is
located on a server that doesn't have Exchange 2013  installed. The arbitration mailbox must be moved to an Exchange
2013 server before you can enable auditing.

Cause: As per Microsoft article http://technet.microsoft.com/en-us/library/dn249849(v=exchg.150).aspx , SystemMailbox mentioned above should be moved to  Exchange 2013 database once Exchange 2013 is introduced into the environment.

Resolution: Move 'SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}' mailbox from Exchange 2010 based mailbox DB to Exchange 2013 DB.

Steps:

1. Find out location of arbitration databases using following exchange powershell cmdlet:

Get-Mailbox -Arbitration | fl Name, Displayname, ServerName, Database, AdminDisplayVersion

It would print information similar to the following

Name                : SystemMailbox{1f05a927-c4a9-4cc7-80bd-a557eb562135}
DisplayName         : Microsoft Exchange Approval Assistant
ServerName          : exchange
Database            : Mailbox Database 0147642087
AdminDisplayVersion : Version 14.3 (Build 123.4)

Name                : SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}
DisplayName         : Microsoft Exchange
ServerName          : exchange
Database            : Mailbox Database 0147642087
AdminDisplayVersion : Version 14.3 (Build 123.4)

Name                : FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042
DisplayName         : Microsoft Exchange Approval Assistant
ServerName          : exchange
Database            : Mailbox Database 0147642087
AdminDisplayVersion : Version 14.3 (Build 123.4)

Name                : SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c}
DisplayName         : Microsoft Exchange
ServerName          : exchange2013
Database            : Mailbox Database 0562670298
AdminDisplayVersion : Version 15.0 (Build 995.29)

Name                : Migration.8f3e7716-2011-43e4-96b1-aba62d229136
DisplayName         : Microsoft Exchange Migration
ServerName          : exchange2013
Database            : Mailbox Database 0562670298
AdminDisplayVersion : Version 15.0 (Build 995.29)

2. Either use information from above to get database names where version is 15.0 or above or use following exchange powershell cmdlet to print information about all databases in your environment:

Get-MailboxDatabase -IncludePreExchange2013 | fl Name, Server, AdminDisplayVersion

It would print information similar to the following:

Name                : Mailbox Database 0147642087
Server              : EXCHANGE
AdminDisplayVersion : Version 14.3 (Build 123.4)

Name                : Mailbox Database 0562670298
Server              : EXCHANGE2013
AdminDisplayVersion : Version 15.0 (Build 995.29)

3. Now move SystemMailbox in question using EAC  (under migration) or using following shell cmdlet (modify  with DB name identified above for exchange 2013)

Get-Mailbox -Arbitration -Identity "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}" | New-MoveRequest -TargetDatabase

How to find list of attributes in PAS (partial attribute set)

Purpose: Sometimes we need to find out what attributes are there in the PAS list used by the Active Directory environment. Sometimes just to make sure there isn't an attribute that you need to exist on all Global Catalog servers for a product or query to work. 


Steps: Following PowerShell command can be run on Domain Controller in your environment to get Display Name of attributes in PAS.

Get-ADObject -SearchBase "cn=Schema,cn=Configuration,dc=YourDomain,dc=com" -LDAPFilter "(isMemberOfPartialAttributeSet=TRUE)" -Properties lDAPDisplayName | Select lDAPDisplayName

Example : 

Get-ADObject -SearchBase "cn=Schema,cn=Configuration,dc=katwal,dc=local" -LDAPFilter "(isMemberOfPartialAttributeSet=TRUE)" -Properties lDAPDisplayName | Select lDAPDisplayName
Following PowerShell can be executed on the Domain Controller to get list of attributes

USB Hard Disk or storage drive cannot be recognised by WINDOWS ?

Issue: At times Windows 7 may not be able to recognize a hard disk or a USB stick e.g. Sandisk Cruzer Slice and same device would work just fine on another Windows 7 machine ? 

In such case following is a solution that worked for me every time.

Cause: System may be missing some entries in usbstor.inf or file could be missing all together.

Resolution: To resolve this issue perform the following steps:

1. Get copy of USBstore.inf located under %windir%\inf\ folder from machine where the same device worked (make sure operating system is same e.g. Windows 7). You can email the same as well by renaming it to .txt file and then changing it to .inf on time of adding it to your machine.

2. On your machine where you have issue go to %windir%\inf\  folder (usually %windir% c:\Windows) and copy the file that you got from another machine where things worked as expected.

3. Launch device manager, you can do this by selecting  Start,   Run, in Open box type devmgmt.msc and select OK button. 

4. In Windows Device Manager look for Other Devices or Unknown Devices section, you will find your device marked with a yellow sign. Right click on your device and select Uninstall.

5. Stay within Device Manager, select Action menu on the top and select Scan for hardware changes.

6. Once scan finished you should see your device appearing properly.

How to allow certain types of file attachments (HTML/XML) through OWA (2010/2013)

GOAL: At times there may be sites that have business case to allow file attachments e.g. .HTML or .XML to be opened/accessed through OWA. Though these are be default not allowed to be opened due to security concerns but there may be sites where it is business requirement. 

STEPS:

From early days of Exchange 2003/2007 there were means available to allow such attachments through OWA. I am only adding here for very recent versions of the exchange only. Especially because they have Microsoft Exchange powrshell cmdlets which can do it very quickly. 

1. Open Microsoft Exchange Management Shell in case of Exchange 2010/2013 

2. Once shell is connected up and running use the following cmdlet to add extension to the AllowedFileTypes 

Set-OwaVirtualDirectory -identity "owa (default web site)" -AllowedFileTypes @{Add='.html'}

This would add .html to AllowedFileList for both "Plublic Computer File Access" and "Private Computer File Access".

In case you are working with an attachment time that is in the BlockedFileTypes or ForceSaveFileTypes list you need to remove those from there first.

After this change now will be up to the internet browser you are using.

For IE 8 it will work like a charm. Users will be able to OPEN and SAVE .HTML attachments as they they like.

With IE 9 and onward there is an issue, it would not allow HTML files to open and same is currently applicable to FireFox (on the time when I am writing it). Another issue is that if you click on SAVE button that will change any URLs within HTML with something like redir.aspx?........

Workaround for this issue is to add .HTML to ForceSaveFileTypes list and then use "Save Target As..." option within IE 9, 10 and 11.

Chrome appears to have no issue at this stage.

To me it appears this is combination of filtering within exchange and the way headers are passed on to browsers. IE 8 and Chrome can handle it but IE 9, 10, 11 and FireFox is having issue.

COMMAND LINES WITH COMMON USE OF FOR LOOP

SOME COMMONLY USED COMMAND LINES ESPECIALLY FOR LOOPS

1.  Create file listing of all files or specific files (bare file names with path) from all subdirectories. It can be used to get listing of all such files on a drive letter.
        ALL FILES EXAMPLE:
DIR /S/B/A-D >> C:\Temp\XLSFILES.TXT

ONLY .XLS FILES EXAMPLE:
DIR /S/B/A-D | FIND /I "*.xls" >> C:\Temp\XLSFILES.TXT


2. Read one text file for path/location of the files and then move those files to a folder. This may be suitable when you have files scattered all  over the place in multiple sub-directories and you only need to move/copy certain files to certain location

    COPY OPERATION EXAMPLE:
    for /f "delims=########" %a in (C:\Temp\XLSFILES.TXT) do copy /Y "%a" I:\DestFolder

    MOVE OPERATION EXAMPLE:
    for /f "delims=########" %a in (C:\Temp\XLSFILES.TXT) do move /Y "%a" I:\DestFolder

3. List file name with path along with its size.
 
   ALL FILES WITHIN A SPECIFIC FOLDER EXAMPLE:
 
   for %F in ("c:\Users\Rajan\*") do @echo %F ------ %~zF

4. Combine logic to create a file listing of multiple file from different sub-directories and then get size of each file.

FILE NAMES AND SIZE USING COMMAND LINE EXAMPLE:
DIR /S/B/A-D >> E:\FileName.txt

for /f "delims=########" %F in (FileName.txt) do @echo %F ------ %~zF 
 
(assumed that user is running second command line from E:\> prompt)

4. If you have large number of text file(s) and you are only interested in certain line (containing specific words) from text file
   (a) Assume you have all your .txt files that are the input test file located in Files folder.
   (b) Create FindText.bat file and add following to it
@echo off
>results.txt (
FOR /F "delims=" %%i IN (TextFind.txt) DO (
FIND "%%i" files\*.txt | FINDSTR /v "^---- ^$"
)
)

Note: This example assumed that command prompt is already pointing to location where the BAT file is located and TextFind.txt is the file containing text that you will be searching for all *.txt files within Files folder.

Microsoft Windows NLB - Configure Exchange CAS high availability

Although for sites with high volume of network traffic coming to the CAS servers it is recommended to have hardware NLB, for sites that are small in size or do not have hardware NLB in hand Microsoft provides Windows Network Load Balancing as an option.

What I am going to mention below is something I built for my lab running Exchange 2013. You may want to check Microsoft best practices for your version of exchange before you follow this post. 

Legal Stuff: I or anyone related to me would not be responsible for any issue or loss caused if you follow this post.

Prerequisites: 

1. Server names used for CAS Servers e.g. CAS1.katwal.local and CAS2.katwal.local
2. Make sure both CAS servers has TWO NIC cards (network interfaces). 
3. Write down IP addresses of the both CAS servers:
     CAS1.katwal.local = 10.0.0.10/255.0.0.0
     CAS2.katwal.local = 10.0.0.11/255.0.0.0
4. Dedicated IP address for NLB : 10.0.0.50/255.0.0.0
5. NLB/CAS URL name: mail.katwal.local  (I assume you already prepared your CAS servers for this alias e.g. SSL certificates are already having autodiscover.katwal.local and mail.katwal.local in their SAN and certificates are already installed on each CAS server)
6. Rename network interfaces that we are going to use on both CAS servers for NLB (to NLB) to make sure we can differentiate them.

Prepration of network interfaces for NLB configuration:

1. As I mentioned above change the network interfaces names to make sure we can differentiate them. In my case I renamed them to NLB.

2. On both servers assign the IP addresses as mentioned above and subnet mask. Make sure you DO NOT fill any DNS information or WINS information.

3. By going to ADVANCED TCP/IP settings screen, under DNS tab uncheck "Register this connection's addresses in DNS" on both servers. Similarly under WINS tab select "Disable NetBIOS over TCP/IP"






4. Check Network Adapter bindings on both machines to make sure NLB adapters are the first adapters in binding. I will give example from Windows 2008 R2 machine below:
  • Open NETWORK CONNECTIONS folder.
  • Press ALT key to bring up the menu bar, go to ADVANCED menu
  • Select Advanced Settings
  • Under Adapters and Binding section, reorder positions of NIC interfaces to make sure NLB is the first interface and other network interface is second.

INSTALL AND CREATE NLB CLUSTER:
By default Network Load Balancing feature is not installed on the servers. Following are the steps to install and configure a NLB cluster:

1. Select START > Administrative Tools> Server Manager

2. Select Features > Add Features,  Select Network Load Balancing Manager, Select Install

3. Close Wizard when Network Load Balancing Manager is installed.

4. On CAS1 server select START > Administrative Tools > Network Load Balancing Manager

5. When NLB Console will start, right click on Network Load Balancing Cluster and select New Cluster.

6. On New Cluster: Connect screen, type FQDN for CAS1 server e.g. CAS1.katwal.local  and select Connect.

7. Select Network Interface with IP 10.0.0.10 and select Next button.

8. On  New Cluster:Host Parameters windows select all default and select Next.

9. On New Cluster: Cluster IP addresses window select ADD button and add IPv4 IP address of NLB cluster which is 10.0.0.50 with subnet mask of 255.0.0.0, select OK, select NEXT

10. On New Cluster: Cluster Parameters window under Full Internet Name section type the URL name selected above: mail.katwal.local 

11. Leave Cluster Operation Mode to be set to Unicast and select NEXT.

12. On Add/Edit Port Rule window, select Finish.

13. Allow some time for cluster to converge and turn into green colour icon.

14. Now log on to CAS2 server and use PING command to check if mail.katwal.local replies back on IP address that was assigned to NLB (10.0.0.50).

15. Just in case there is some issue with getting the reply back, check DNS Server configuration.

16. To add CAS2 server to the NLB Cluster open NLB Manager Console

17. Right Click on the cluster (mail.katwal.local) and select  Add Host To Cluster.

18. In Host Field type FQDN for CAS2 server (CAS2.katwal.local) and select Connect.

19. Select NLB interface with IP address of 10.0.0.11 and select Next, Next.

20. Leave everything to default as we did earlier and select Finish.

21. Now you should see second node of CAS2 will start to converge just as CAS1 did earlier and you should see it with the green icon.

22. Verify that when one of the nodes is turned off from NLB Manager we can still get reply for URL (mail.katwal.local) from IP address 10.0.0.50. Additional test will be to turn of both nodes from NLB manager and check if we cannot get to mail.katwal.local and then start only one node at a time.  

23. If using virtual machines you may want to have static MAC address that was provided when cluster was configured. You can get to it by using NLB manager and get to to the properties of Cluster and selecting Cluster Parameter tab. Once you have the MAC address if you are using VMWARE you can go to the properties of NIC we used for NLB and add the MAC address for making it static. Similarly in Hyper-V Manager configure NIC used for NLB and fill  in info under Static section. on Hyper-V also select Enable Spoofing of MAC Addresses.

24. To confirm changes to NIC have not broken anything restart both nodes one at a time and confirm that both nodes converge without issues.

25. Next step is to make sure NIC forwarding is done so that all OWA requests only go to NIC selected for NLB. Following is example of the command I ran on both of my CAS servers. 

netsh interface ipv4 set interface NLB forwarding=enabled

Make sure you start command prompt using Run As Administrator. Reply expected after running above command line is OK.

26. Now you can go ahead and start with Exchange Server 2013 Servers control panel (ECP) to define Internal and external URLs as you want those.
