outlook-crash

Microsoft Outlook is immediately crashing upon opening when users start the program, with 0xc0000005 errors in Event Viewer.

These crashes started the last hour and reports are flooding in from all our clients and over the world. Thanks Microsoft!

The App event log, shows OUTLOOK.EXE crashed with code 0xc0000005.

An outlook rollback to 16.0.12827.20470 seems to fix this issue.
