I have a couple of clients that are experiencing issues today (11/11/15) with Outlook 2013 crashing either immediately after opening or as soon as the user starts to access e-mail items or click to view a different folder. One client is using host Exchange through Microsoft and the other client has a local Exchange server. Not all users running Outlook 2013 are reporting experiencing the problem. However, several are and some (myself included) are experiencing it randomly. The error is the Outlook stopped working and needs to close basic message. There are tons of hits and offered solutions to this when searching the Internet. However, none of these seem to apply to the situations I am experiencing. For the client using hosted Exchange I unchecked the box enabling Cached Exchange Mode. This allowed one user that couldn't even get her Outlook to stay open at all to open it and access e-mail items. I tried this same setting for a user at the client with the local Exchange server and it seemed to help a little but Outlook still crashed almost immediately if she tried to access anything. The only thing I can find possibly in common on the PC's I have actually touched is that Adobe Flash Player 19 ActiveX installed (updated I assume) either yesterday or today on the PC's. On one, I uninstalled Flash Player but it didn't resolve the issue. I am guessing possibly that this update possible overwrote or misconfigured a DLL. Has anyone else experienced this issue today and does anyone have any ideas on a permanent solution?
