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.......
Same problem since this morning. Opens in safe mode but won't open in regular run mode. ALL add-ins disabled. Reinstalled and repaired.
There's a note on this thread about this (https://blog.lan-tech.ca/2020/07/15/outlook-fails-to-start/) potentially fixing the issue, however I noted that at present the update mentioned on this page isn't installed on my machine but is a pending update. But maybe worth having a look for some of you?
