What I eventually realized is that you need to look for messages that contain the word “Unexpected” - Microsoft would it kill you to adhere to syslog RFC standards is use something like “error”? - note using grep on the file did not work for me so I used vim and its search capabilities to look for Unexpected messages. Tailing this log while reproducing the issue will result in a lot of output. Then you reproduce the issue and check the logs - the big question is where are the logs? Unfortunately, Outlook does not tell you this either, but you can find it in: ~/Library/Containers//Data/Library/Logs. Then you need to close Outlook and open it again - wish it would state that. To do this, you go to Tools > Sync Errors > Gear Icon > Turn on logging for troubleshooting. Next up, I enabled troubleshooting logging. After completing this, I reinstalled Office, but the problem persisted.

I, of course, ensured I was running the latest version of Office and then did what Microsoft typically recommends - manually uninstall and manually reinstall Office for Mac 2016. This time I could easily check the logs so I did, but unfortunately, they did not report any issues. What was going on? Read on to learn more!


Any time I deleted an email it would shortly reappear in the same folder.All Calendar invites/updates/removals arrived as empty messages.After fixing the issue, I noticed that Outlook was behaving oddly including: In my last post, I covered an error message I received randomly on mac os.
