Hi,

Lync Add-in gets auto disabled on Outlook 2013. This add-in needs to be manually enabled each time Outlook is launched.

OS used is Win 8. How do I ensure that this add-in remains enabled permanently.

Troubleshooting Steps tried thus far :

1. Reinstalled Lync

2. Repaired the entire Office 2013 package

3. Creating a new Outlook profile didnot help either.

Your valuable inputs would be really appreciated.

Hi Arjit,

First, I want to make sure, when you said "Lync Add-in", do you mean the "Lync Meeting Scheduling Outlook Addin"?

If so, please check the COM Add-Ins settings, make sure the Load Behavior is set as Load at Startup:

.

If the Load Behavior is correct, please try to disable all the other add-ins and restart Outlook to determine if it is caused by conflict with the other add-ins.

I am also having the same problem.. I have disabled all other add-in.. the problem of Lync add-in keep on showing as inactive when I restart outlook. I have to check box it every time

My Situation

Had to re-enable Lync Meeting Add-In in each time Outlook 2013 was started as it was not set to "Load at Startup".

Resolution

1. Starting Outlook 2013 as an Administrator (right click, run as Admin)
2. Outlook, File, Options, Add-ins, Manage Com Add-Ins Go..., Lync Meeting Scheduling Outlook Addin, Remove, OK
3. Outlook, File, Options, Add-ins, Manage Com Add-Ins Go..., Add..., C:\Program Files (x86)\Microsoft Office\Office15\UCAddin.dll, OK
4. Close Outlook and start it as a normal user.

Hope this helps.

Work great  - thanks - although since I am using 64 bit the UCAddin.ddl was in the folder c:\program files\microsoft office\office 15 rather than ...program files (x86)..

THX worked perfect.

Worked for my user also.  Thanks!  Wish I saw this before the hour of troubleshooting!

Unfortunately did not Work in my case...
I have checked that LoadBehavior is set to 3 on the users pc. Seems I must investigate further.

I randomly had the same issue all of a sudden and this worked perfectly.  Thanks!

It has solved my issue. Thank you.
