Outlook won't start

[Martin_Hughes]

"Cannot start outlook. Cannot open the outlook window. The set of folders cannot be opened.  An unexpected error has occurred"

I followed all the steps so far in the help section.  Will open on the 3rd attempt if you click yes to "do you need help"..  then cannot open a help ticket.. 

ffs..

Help please?

IMHO, those errors point to a corrupt PST. Try turning off cache mode, or delete your mail profile and create a new one

@mmorganMIT IMHO you are a bleedin' legend! Profile it was. New profile fixed it.  Thanks so very much!

I have the exact same problem, but I'm unsure how to get into my profile if I can't open outlook.

@Martin_Hughes I was facing the same error. After trying everything, this finally worked: https://youtu.be/BUFHhDMFi7E
