Most staff unable to sign in to O365 due to Exchange Online Problem

[ronnoco]

Hello all,

 

I'm just curious to see if anyone else is affected by the know issues of ID EX220974 and EX221135 where by if a user tries to sign in to O365, they get a 'sorry, that didn't work' message. For over a week this has been affecting us and has caused HUGE problems. Staff were supposed to be doing remote training on Thursday and Friday but at least 50 staff members had to come to site because they couldn't log in at home. Even it site, it rarely works.

 

We have 1500 users coming back tomorrow and i'm dreading that it wont be fixed. Microsoft have confirmed it's an IIS problem their end but at the moment, we're pretty helpless :-(
