Office 365 Outlook Crashes with Multiple Mail Windows Open

When using Outlook desktop, the application crashes and restarts if I open up a new mail window. For example, if my inbox is open and I open a new window for sent items. It does not happen if I open up multiple other window types such as tasks, calendar, notes while a mail (inbox/sent/drafts) window is open, only when I open multiple mail windows. I am running this on two Dell machines running Windows 10 Pro and it only occurs on one of the machines.

Hello Hayes, and thank you for your comment.  Outlook version: Microsoft Outlook for Office 365 MSO (16.0.12527.20260) 64-bit. I don't know what you mean by patched. I don't know how to view the event log. I have already tried the troubleshooting steps with no resolution.
hey - fair enough.

Yep, if you are O365 - you are likely current.

Event log - go to your start menu - type in "event" - and you will likely see event viewer turn up as an option....

once in event viewer go to Windows Logs | applications.... there will likely be an error entry in there associated with the crash. This may (or may not) give us a hint as to the root cause of the issue.

I would start with running Outlook in the safe mode/without any add-ins.
Then I would recreate the Outlook profile.
Then MS Office online repair.
I just ran a quick repair from control panel and problem solved. Sorry I missed this step earlier. Thanks for your help.
