Outlook for Mac 15.3 (Outlook 365) gets hung up on Sync Pending

For anyone using Exchange, please verify you’re connecting to Exchange Server 2010 SP2 or higher.

Got Outlook 2014 for Mac and Apple Mail running side by side.  For the last hour, Outlook 2014 for Mac is not receiving my email and it just lamely claims "Sync Pending for this Folder".  Apple Mail is happily receiving my new email thankfully but it's so patently obvious Outlook 2014 is fundamentally broken I'm in shock nobody from MS has addressed this yet!

Did not work for me either. The only result is that the message "sync pending for this folder" no longer appears in the blue status bar. Emails still do not come in. This seems to be a "real" issue so I hope someone from the Outlook for Mac team is watching this thread...

For me it makes it worse as it shows all folders are up to date but no new mail shows. Working fine in the cloud as my phone is up to date. Looks like I will have to roll back to Outlook 2011. I can't believe no one from Microsoft has said a word..

[Solved - at least temporarily till a fix is released]

...

That's it, Outlook should stay synced now. 

This did not work for me. I still get "Sync Pending". Furthermore it doesn't even seem to generate the log files, or, the spot it mentions to look is not the right spot for logs.
