Hi all, this popped up for my colleagues recently so I did some digging.
Teams Meeting Add-In is the culprit.
After disabling this me and my colleagues can opened saved email multiple times without issue.
How to disable
File > Options > Add-in > Go > Untick Teams Meeting Add-In
Full diagnosis below.
SYSTEM
Windows 11, 64 bit,
Microsoft® Outlook® for Microsoft 365 MSO (Version 2306 Build 16.0.16529.20100) 32-bit
I have run Outlook in safe mode (Start > Run > Outlook /safe) and this works fine...
So it must be one of the add-ins... I have done some extensive testing and found the answer
There are 11 add-ins (on my system)
- AntiVirus Add-in is enabled by default by the administrator, so I cannot turn this one off.
- Microsoft Access Outlook Add-in for Data Collection and Publishing is disabled
- Sykpe Meeting Add-in for Microsoft Office is disabled
Leaving 8 for testing - I have enabled each one and left it enabled until I replicated the issue:
- DSTNY (my phone app) outlook add-in enabled - tested - works fine
- Microsoft Exchange Add-in - tested - works fine
- Microsoft SharePoint Server Colleague Import Add-in - tested - works fine
- Microsoft Teams Meeting Add-in for Microsoft Office - tested - FAILED - DISABLED TO CONTINUE TESTING
- Microsoft VBA for Outlook Addin - tested - works fine
- OneNote Notes about Outlook Items - tested - works fine
- Outlook Social Connector 2016 - tested - works fine
- TeamViewer Meeting Add-in - tested - works fine
- re-enabled Microsoft Teams Meeting Add-in for Microsoft Office - tried again - FAILED
