My organization uses Office365 Exchange Online as our email platform. We are primarily a Windows organization, but we have one user who is committed to Mac.

Recently, he is seeing major delays (upwards of an hour or two) in receiving emails in Outlook. No problems on the web platform, so the emails are definitely getting into his account. Additionally, they are getting down to his phone as quickly as they should. The problem seems to be specific to Outlook for Mac.

Interestingly, he is connected to several accounts through Outlook, but only having this issue with the Office365 account.

Based on the timing of the issue (and a preliminary Google search on the topic) I have suspicions that the issue is related to the recent Outlook for Mac patch. I have nothing concrete to back that up, however.

Sometimes he needs to reboot his system fully to force a sync with the server. Closing Outlook and reopening the program does not seem to make a difference.

Has anyone had a similar issue in the last week or so? Does anyone know of a potential fix?
