Hey Everyone,
Just joined the community today after reading some helpful troubleshooting info in a few articles regarding Office 365. I handle all employee support for our company and I'm relatively new to the Office 365 Platform (we just implemented it last month). We are running Office 2010 for the most part, but some users are on 2013.
For most of our users, the transition to Office 365 has been fairly smooth...but for a few, there have been persistent Outlook Connectivity issues ranging from spotty connections to the MS Exchange server, to Send/Receive/Outbox hangs to Outlook completely freezing up, crashing, and e-mails in the outbox being lost. The last scenario is probably the most drastic I've seen, and the one I'm really needing some help on.
For one user that had the send/receive connectivity issues, it turned out she had to update the firmware on her router and once she did that her connection issues were resolved. This is not the case with the user reporting freezing, crashing, and then failed sent messages.
The only difference I can see in her setup vs. everyone else is she probably uses more PST files than anyone else at the company in her day to day usage of the application. She says she navigates around in Outlook between these PST files and 3 times now since we have implemented O365, she has reported that as she's navigating around and doing things with the PSTs, she gets the attached error, Send/Receive hangs, the messages she's sending remain in her outbox, Outlook freezes, crashes, then the e-mails are not only not sent, but completely gone upon restarting the program.
She is the only user reporting issues like this...and I can't imagine it doesn't relate to her heavy use of PST files in Outlook. Im wondering if maybe some of the PST files she's using are from older versions of outlook (Say, 2003 or 2007)...but I'm not sure if that matters?
Any assistance on this would be greatly appreciated...Im scratching my head at this point.
