Had a customer ask about the Lync Outlook Plugins today.
There are actually two plugins for Outlook
Conversation History Add-in for Microsoft Lync
Usually located at C:\Program Files (x86)\Microsoft Lync\ocoffice.dll
Online Meeting Add-in for Microsoft Lync 2010
Usually located at C:\Program Files (x86)\Microsoft Lync\ucaddin.dll
They are deployed as part of the Lync client install. There is no separate installer available.
Does this remove the OCS/Live Meeting Outlook plugin?
Not by default, but you can get the Lync installer to remove the previous Live Meeting plugin by using the following switch
Removes the Conferencing Add-in for Microsoft Office Outlook, which is the previous version of the add-in (used for scheduling Microsoft Office Live Meeting server- and service-based meetings).
Can I have pictures of my Lync contacts in Outlook?
Sure, tommy clarke has a good expenlation of how to enable this here
What if I don’t have Outlook/don’t want the plugins?
