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.......

Exact same thing happened to me. Office 365 programs all vanished as did Skype. I had to download and reinstall all software. Steven_F_603
Same here (Germany)
Since updating Windows, Outlook doesn't start anymore. (Office 2019)
- Trying the safe mode didn't help. Splashscreen appears, but seconds later Outlook closes
- To downgrade to previous build from 2016 also didn't help,- same issue
- Deleting the *.ost entry from the registry also didn't help
- Installing the Office Suite completely fresh - no success
- Deleting the Windows update - no success...
We cannot work with Outlook - and this is very important.
Microsoft,- it is urgent! Deliver a hotfix immediately!
Same problem here . It will open in "safe mode" but not in normal.
This is so frustrating. I uninstalled the recent update and Outlook still doesn't work.
Microsoft is pushing out a fix. It is applied simply by closing and reopening Outlook. It may take a few more hours to reach all machines but I have seen it repair several already, as well as others have reported the same.
Many thanks Rob and everyone. Apparently my machine received the fix - Outlook is now working.
Best regards to all.

Outlook just came up ok, I am in UK, must be fixed.
So awesome! I just rebooted and opened Outlook 365 on my computer and Hallelujah, it works! Yeah! Thanks Microsoft for listening to all of us 🙂 joncool85
Hi all, here's my update for you all. So I've just been through and installed the three available updates to me which includes one that was suggested uninstalled. The update took sometime, one of the updates was a full Windows update, reckon about 40 ish minutes beginning to end of install and after restarting to complete the update Outlook worked without intervention. So MS have either fixed these updates now or there's a further issue if using Outlook to synch with an online mail system running Exchange. All my email accounts are POP or IMAP so am local running Outlook only.
I'm now showing no updates available in Updates and in the installed updates the list has completely changed, I'm guessing because of the update to Windows itself. Have screen grabbed and attached my Windows version.
- I don't know about the OP's case but rolling back didn't help my Outlook situation at all.
Steven_F_603Ran the 2 line cmd prompt edit suggested above. Didn't appear anything was happening, but when I closed the cmd prompt the Outlook box reappeared I clicked no, don't start in safe mode a couple times. Outlook began to open (successfully) and I have a Microsoft pop-up 'Downloading Office updates... You can keep using Office while we download in the background.' Crossing my fingers. Good luck to all.
I've had the same problem ever since I ran the latest Microsoft update this evening. Outlook opens for a few seconds then closes so I can't access my emails! Very frustrating!
Same problem here - Surface Notebook.
Just installed the latest kb456483. kb4565633 and KB4565554.
I am in the process of removing them.
Steven_F_603 I had the same issue since morning. Waiting for hours on the phone to MS support! Created ticket still waiting on it.
I resolved the problem by request to download and re-install Office software on top of the current installation.
After that, Outlook opened immediately
Total time to resolve: 10 min
