Outlook 365 suddenly won't open
Steven F, original poster here: my Outlook just fixed @ 1:20 Pm pst, I tried it and it opened right up. Hope the same for all of you, maybe 1 at a time! Thanks all.......
Running into the same problem with 10 of my customers so far this morning. If anyone has any insight I would like to hear it
DanFriendly I have had luck with some clients by starting Outlook in Safe Mode, by either adding /safe to the shortcut or holding down the control key while clicking it.
Reporting 3 impacted clients starting this AM, two of which with multiple affected machines. Starts to load then disappears without a message.
Ok so tried downgrading my O365 Current Channel v2006 Build 13001.20384 to Build 13001.20266 (the build working fine on my other laptop which has not installed the July patches yet!).
Outcome: Outlook still crashing....
Meanwhile installed the July patches on my laptop (Windows 10 v2004 Build 19041.329), rebooted, started Outlook and works like a charm.
Now downloading the O365 Current Channel update to 13001.20384... see if I can break it.

Rolls back to previous version
Thank you. We started rolling this quick fix and it does work. Just waiting for MS to patch the actual problem.
- This worked for me. Reddit FTW!
