Am I using Office 365 after the service upgrade?
When you sign in to Microsoft Lync Online by using Microsoft Lync 2010 on a computer that is running Microsoft Outlook, you receive the following error message:
Additionally, you may experience the following problems:
There was a problem connecting to Microsoft Office Outlook. Outlook is not installed or configured correctly. Repair or reinstall Outlook, and then sign out and sign back in to Lync.

These issues occur because Lync, Outlook, or the Lync Add-in for Outlook installation is corrupted and has to be reinstalled. Repair or reinstall Outlook 2010 and Lync 2010, and then sign out and sign back in to Lync 2010. To do this, follow these steps:
Lync 2010 connects to Outlook through a MAPI connection. If Lync can't make that connection, the features that are listed in the "Problem" section may not work. Or, you may be prompted to connect to Microsoft Lync 2010 MAPI COM Server. You should enter the credentials to connect Lync to the Exchange mailbox and then view the MAPI Information area in the Lync Configuration Information screen. (To open the Lync Configuration Information screen, hold down the Ctrl key, and then right-click the Lync icon in the Windows notification area.) The MAPI Information area may display something similar to the following:

If the MAPI connection is down, verify that UCMapi32.exe or UCMapi64.exe is running in Windows Task Manager. The UCMapi process is responsible for making Outlook and Lync communicate for certain functionality. UCMapi is started about 30 seconds after Lync starts. However, if the process stops responding or is otherwise prevented from running, the MAPI connection with Outlook will fail.
