We just migrated from Google Apps to O365 this weekend. Mostly we love it. However, I've noticed that sometimes now, my Outlook 2010 goes non-responsive on me. My only option seems to be to restart it. I've seen other post about it trying to connect to the server, but I see no indication of that. It says "This folder is up to date" and "Connected to Microsoft Exchange". Clicking into the window causes it to go dim and after a time Windows pops up a program is not responding message with restart or wait.
If I wait long enough, say 10 minutes, it sometimes comes back. I can reproduce this at will because I've found it does it when trying to reply to a specific message. WHat are my troubleshooting steps. Should I open a case with Microsoft? Thanks.
