Dear Patrick Vanstrom
Thanks a lot for your feedback and patience! Very sorry for late reply!
Based on your further description, first I would like to explain to you that I asked you to check the results on Outlook on the web, not to let you escape the error of the Outlook client to use Outlook on the web as a replacement, but to further troubleshoot the cause of the problem, if the problem occurs on both the Outlook web version and the Outlook client, it means that the problem is not related to the Outlook client, it may be related to your account and the server backend, But if the same error does not appear on Outlook on the web, then please kindly try to fix the Outlook client by doing the following
your issue not occurred in OWA(outlook web app), so that means your problem is related to your outlook desktop client, so please kindly refer to following
If you still need further help, then please kindly share with me the above feedback after you tried it, and I will do my best to do more research and testing to help you further, thank you.
Sincerely hope that your problem will be solved as soon as possible! Wish you have a wonderful day!
Sincerely
