O365 Outlook for Mac is a great program but as with most any app there are some issues. This particular issue is a bit over the top – crazy stupid, but also very easy to fix.
Issue – You have a network connection but your Outlook for Mac client just stops receiving email. No email. None. And the mailman isn’t coming round no matter how many times you restart the app or computer.
Solution – Put your Outlook client in Offline mode and then switch back to Online mode.
- Go to the Tools menu > Slide the Status slider to Offline > Slide back to Online
- You Have Mail!
