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 60...

    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.......

Steven_F_603 I also had the Windwos Updates this morning and my Outlook 365 wouldn't open since. It did open in Safe Mode (Outlook.exe /safe). I just did a System Restore from earlier this morning, from the restore point before the installation of these updates and now my Otlook open fine. Just to be sure, I stopped Windows Update for 5 days.

    fdupuisI have the same experience. Outlook stopped launching or opening correctly this morning. I can open in safe mode. If I try to open it in the regular mode, it does not open (interestingly, I do see an Outlook icon in my system tray like usual, but if I click it, it just disappears!)
