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_603I've got the same issue with 3 of my users so far one had an update to their Windows 2004 build last night, but the other 2 didn't have any updates. Started around 11 am this morning and it's also effecting shared mailboxes. I've had users sign into Office 365 online to be able to work.
