I have been using Outlook 2010 and Lync on my PC for quite some time and have what I assume is a healthy environment supporting 400 users.  Recently we have seen an issue popping up on PC's where for no apparent reason integration between Lynch and Outlook 2010 goes missing.  Calendar and presence information is still working, but the ability to IM Reply or see the presence indicator in Outlook next to people's name is gone.

You can read their contact card and see photo's, just no program type integration.  If you try ti IM a person it says "To use this feature, sign on to an instant messaging program".

We have tried uninstalling and reinstalling Lync and also removing users roaming profile.

We cannot find a fix and I could use some help.

Hi,Daniel,

Would you please tell us if you have done some changes involve Exchange or Lync server?

Here are some suggestions:

1)Please check the all the reuqired add-ins in outlook as Matt advised.

2)Please try to uninstall outlook,reboot computer and reinstall outlook again to see if it works

2)Please make sure you have outlook and Lync client are fully patched.

Lync client updates  http://support.microsoft.com/kb/2684739 

Outlook updates   http://support.microsoft.com/kb/2553248

3)If you are using outlook 2010 64 bit Please copy everything that is present in HKEY_LOCAL_MACHINE\SOFTWARE\IM Providers into

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\IM Providers  then reboot the computer.

4)Here is an old thread  with similar sceanrio just for your reference.

If still no luck please elaborate more on your productions version and enable Lync logging tool,reproduce the issue and use snooper to analyze the uccapilog file to get more specific information.

Unfortunately I am not making any progress.  See replies for your suggestions.  Also I have the exact symptoms of the old thread.  Where the "display online status next to name" field in Outlook Options - Contacts is greyed out.  All Lync functions appear grayed out (like respond with IM).  There is NO presence skittle at all...it's not there but grey....just not there anymore.

Seeing how we have an environment with over 400 users in Lync and Outlook 2010 I am highly suspect of any global config issue with Lync or Exchange being the culprit.  I would say it has to be something on the workstation.  To rule out any profile issues I deleted my mail profile entireley and recreated.  Also I deleted my roaming user profile AND the server copy to start afresh.

1.  My ucaddin.dll is installed and I can click the New Online Meeting but I get an error:  "Lync must be running and signed in before working with online meetings.  In addition, its privilege must be the same as Outlook".  This behavior has led me to some other forums but nothing is working.

2.  Try uninstall of Lync and Outlook with no results.  All patches installed.

3.  Lync is correctly listed in both this reg keys.

4.  Good info with similar symptoms but no fix.

I think I may have found the issue but dont know how to troulbeshoot or fix.  My oulook DOES NOT have the ocoffice.dll addin loaded.  And I cannot seem to add it.  That's the only difference I can find between me and a functioning machine.

Hi Daniel,

Can the affected users see the UC integration in OWA, i.e. is this an Outlook-only issue?

Rory.

ocoffice.dll is labeled as "Conversation History Add-in for Microsoft Lync 2010" with a default location of "C:\Program Files\Microsoft Lync\ocoffice.dll" (on a Windows 7 32bit machine).

Did your Outlook version change by chance?  Is your Lync client configured to use Microsoft Exchange or Microsoft Outlook for the Personal information manager (in the Lync options)?

Hi,Daniel,

Any updates here?

Actually,the old thread owner has solved his issue by downloading and installing windows messenger(see the bottom of that thread).Have you tried that solution either?

How did you reinstall outlook?Did you remove the old files and restart your computer when you uninstall your outlook and reinstall it? 

Again,please tell more about your OS version and other products version number(such as outlook)  and compare them on your computer and the working computer.

Daniel, I recently had the same issue with some of my users. The Online Meeting option was also missing. In Outlook 2010, I went to File > Options > Add-ins > Manage Drop Down (at the bottom) > Disabled Items. I selected my Lync add-ins and enabled them.

Hi Guys,

Can any one update me on this issue, please?

Win7 SP1, Lync 64bit, Outlook 2010 32bit.

Cheers,

H.

For what's it worth whenever this happens here we just run a repair of Lync and it resolves the issue.

Can you be more specific to the steps involved to "run a repair of Lync"? Is the repair run on the user workstation, or on a Lync server?

The repair should be on a Workstation, if that doesn't work I sometimes repair the Outlook and Lync together which clears out this issue most of the time. This wont work out, if you want to target mass number of users.

Thanks, could you provide steps to "run a repair of Lync" on the workstation?

Sorry that I am getting to your question a real late.. but, I would do the repair by going to Add/Remove Programs and find 'Lync' in there > Click 'Change' and > hit 'Repair' from the setup dialog box..!

I know I'm reviving an old thread, but to add my experience: Ran into the issue after installing Lync 2013 but keeping the rest of Office at 2010, I uninstalled Lync 2010, then the integration disappeared. Re-installing, updating 2010 seemed to do the trick. Currently:

Inactive Application Add-ins: "Lync Meeting Add-in for Office 2013". (\Program Files\Microsoft Office 15\root\office15\ucaddin.dll)

Active Application Add-ons: "Conversation History Add-in for Microsoft Lync 2010" (\Program Files (x86)\Microsoft Lync\ocoffice.dll) and "Online Meeting Add-in for Microsoft Lync 2010" (\Program Files (x86)\Microsoft Lync\ucaddin.dll)
