Hi,

Hoping someone can confirm/advise on a problem I'm seeing with a user trying to sign in to Word with their Office 365 account.

The username has an apostrophe in it i.e. fred.o'connor@xxxx.com and when the user tries to sign in to Word they get a message stating "there is a problem with your account. Please try again." or words to that effect.

Is that a known issue? If so, is there any way around it short of removing the apostrophe from the username?

It's not an issue with Outlook, that works fine. Just other Office apps. 

This relates to the client version of the apps not the online versions.

Any advice would be appreciated.

Mark
