Hey Team,
we have one particular user who whenever she responds to a a number of emails (completely random in terms of sender, subject, content) her response cause the recipients Outlook to Freeze. for a period of 3 to 30 seconds each time the message is opened.
A lot of troubleshooting has been done on this and we currently have a CritSit with microsoft support opened.
The issue is reproducible
- By Microsoft support using their own outlook
- By me when opening up the message in my outlook
- on a newly provisioned VM
- On a system (via RDP) to a regular installed (Non vm) Machine
We,re now at the point of using procmon and process explorer to "investigate" but i am curious as to what to look for in those captures? Also outlook logging is enabled, and ETL Files are being reviewed By Microsoft (2nd set).
I am asking for more of a "What else can be checked" or "How do i check for this in procmon" rather than a solution. (Hopefully Microsoft will provide that).
Happens on version 2308 and 2401 of Office 365. Windows 10. Additionally if you try to save the messages you get a "Cant save message error" if you try to send the messages outside of our domain, you get a message conversion / bodyconversion error.
I wonder if this is logical corruption?, Except she can send other emails just fine.
Thanks,
Robert
