Microsoft Lync




I recently found myself defending Lync when a user claimed that Lync was delivering instant messages to wrong person. I knew that there had to be perfect explanation for this kind of behaviour. I had previously received a similar complaint which was slightly different in that the other one was querying wrong picture displayed.  The real question that comes to mind is, Reaaallly, is it possible that Lync could misdirect an IM and send to wrong person...

Lync 2013 mobile client brings a significant number of new features. The new mobility clients are supported on almost all of the available mobile operating systems. The only exception to this list is the Blackberry OS 10 found on the Blackberry Z10, Q10, Q5 and Z30. Blackberry runs its owversion of Lync written and maintained by Blackberry.

Backwards compatibility

The new mobile client does not support any other Lync Back-end System such as Lync 2010 or any version of OCS. It requires Lync 2013 backend server system. You can always with your IT department on which Lync Server system you are running.

Lync addicts can give weird requests. Today a user complained lync online presence is not working in outlook. I thought to myself, why would someone wants to view someone elses Lync presence in outlook. You can simply lookup the person in Lync client and send an IM. So i called the user to hear it from the horses mouth. And yes, that was correct, she could view the presence in lync client, but she always views in outlook, and she wants it back.

Below is screenshot from one of the cases. Lync online presence is not working. The same contact when viewed from Lync Client. The contact has presence working correctly. Please note Lync Presence does not work in outlook for all contacts.

So I set out to find the cause and the fix. As it turns out, this user was migrated to another domain. Lync exists in a different domain. Email address and Lync are sip address are now different.Hence Email comparison check was failing. The solution is detailed here on this Microsoft KB

Disable the email check.  To do this, follow these steps.

1. Click Start , click Run, type regedit, and then press ENTER.
2. Locate, and then right-click the following registry subkey:
3. HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Communicator
4. Point to New, and then click DWORD Value.
5. Type DisableEmailComparisonCheck as the name of new registry entry, and then press ENTER.
6. Double-click DisableEmailComparisonCheck, type 1 in the Value data box, and then click OK.
7. Close Registry Editor.
8. Restart Lync 2010 and Outlook. 

 After the change here is my happy outlook client
