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 Same issue here.
Some info regarding my pc:
Windows 10 v1909 Build 18363.959
Installed today:
- KB4565633 (2020-07 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 version 1909 for x64)
- KB4565554 (2020-07 Servicing Stack Update for Windows 10 Version 1909 for x64-based Systems)
- KB4565483 (2020-07 Cumulative Update for Windows 10 Version 1909 for x64-based Systems)
I'm uninstalling KB4565483 now as that one does list "Updates to improve security when using Microsoft Office products." in the highlights.
I've tried creating a new Outlook Profile, No success. I've now uninstalled all but the Security Update KB4565554. Still doesn't work. Andy D'Hollander
