Good Morning,

     I was wondering if anyone had an explanation for why Microsoft Updates break IMAP connections in Outlook 2010 every month? It is not always the same KB, but it is always an update titled "Update for Microsoft Outlook 2010". This month (April) was KB2965295. Our environment is described below;

-Windows 7 Enterprise x64

-Microsoft Office 2010 Professional Plus (32-bit)

-Each user has 2 mailboxes. An Exchange Account for email and an IMAP account that connects to our Cisco Unity Voicemail Server.

After the updates gets installed, whenever a user attempts to open their IMAP account Outlook crashes and provides no error code.
