Outlook 365 suddenly won't open
Hello; Outlook worked this morning, now it won't open, says to open in Safe Mode, but that doesn't work, tries to open for 5 seconds than nothing. Restarted PC and no help. Please advise! Steven F 603
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.......

This fix worked - thank you so much for whoever shared this.
open cmd, run:
cd \Program Files\Common Files\microsoft shared\ClickToRun
then enter:
officec2rclient.exe /update user updatetoversion=16.0.6366.2062
Good luck
This worked for me as well! Thank you!

Frank_Petrus That version would depend on which O365 Update Channel you are on though.
I'm having the issue with Current Channel: Version 2006 (Build 13001.20384).
So I would need to go back to Version 2005 (Build 12827.20336)
The 16.0.6366.2062 listed in that 'fix' is an Office Insider build from 2016... Probably don't want to go all the way back there 🙂

Same here : Try this > (Open in safe mode) Use Ctrl + Open Outlook via Icon, then open Options >> and check Prompt for a profile to be used. Then click OK. This opens in safe mode for me, although only a temporary fix.
Steven_F_603 Yes having the same problem, along with several others in my company.
Get on it Microsoft and give us a fix asap!
Looks like this is a pretty big issue. I'm running a new install and, as of today, re-install of Office 365 with the same issue. Outlook will not even start in safe mode and when I try to download the SARA tool I get: "This solution isn't supported for your Office environment." Not happy. Awaiting response with you...
This worked on Office 2016. Going to try Outlook 365
Replying tohttps://twitter.com/Kevin_SmallwoodFIX FOR OUTLOOK CRASHING ISSUES:Open cmdRun: cd “\Program Files\Common Files\microsoft shared\ClickToRun”then: officec2rclient.exe /update user updatetoversion=16.0.12827.20470- I can confirm this fixed O365 for me
I have same issue... in Seattle, WA Steven_F_603
It opens in safe mode. I tried to trouble shoot by disabling add-ins but no luck. After reading this thread, it sounds like a MSFT issue.
Same problem over here. I cannot even get Outlook 365 to open in safe mode. Word and Excel work perfectly. Desperate for a solution
The exact same thing happened to me 30 minutes ago. Nothing has changed on my computer and I have never had a problem with Outlook before this.
djfTacoma try tu run this command from MS DOS i did and work ok form me
c:\"Program Files\Common Files\microsoft shared\ClickToRun\officec2rclient.exe" /update user updatetoversion=16.0.12827.20470
Same issue... restarted, shut down, ran CCleaner, AntiVirus, etc... no access to Outlook... help!
same thing here. It worked this am (app still open from last night). Once I closed the app, I couldn't reopen it. Strangely, I closed the app to restart the computer because a different app (Quickbooks) wouldn't open. Once I restarted, quickbooks would open but outlook wouldn't. Restarted again and outlook still wouldn't open. On autoupdates. Other office products - word, excel, powerpoint - all are working.
