Microsoft has pulled the Microsoft 365 version 2206 update after users report their Office applications are crashing when viewing a contact card or hovering over a user’s name or photo.
The bug was introduced with the Monthly Enterprise Channel version 2206 (build 15330.20298), released Tuesday as part of Microsoft’s August Patch Tuesday.
When attempting to open a user’s contact card or hover over their name/picture in emails, comments, or shared documents, the application will crash with 0xc0000005 and 0xc0000374 exception errors.
According to reports on Reddit and the Microsoft Answers forum, this is a widespread problem, with the only fix to downgrade to Enterprise channel 2205, released at the end of July.
“Just upgraded to Office 2206 in Monthly Enterprise Channel and whenever you move the cursor over the picture or icon of the sender of an email, outlook immediately crashes,” explained a Microsoft 365 on the Microsoft Answers forum.
Microsoft is aware of the issue and has released the MO412229 advisory stating that they pulled Microsoft 365 version 2206 while they gather diagnostic data to investigate the cause.
“While we’re continuing to investigate precisely why this occurred, we’ve reverted to the last known unaffected version to expedite remediation, subsequently confirming resolution with some formerly affected users. ,” reads the Microsoft advisory regarding these crashes.
Microsoft 365 users already on version 2206 are advised to roll back to version 2205 to mitigate this issue.
Admins can roll back to Microsoft 365 version 2205 via the Microsoft 365 admin center or using these instructions.
Microsoft suffered an outage yesterday after a Cisco Meraki Snort rule prevented EMEA users from connecting Microsoft 365 services.
