Office 365 webmail and password issue

Copper Contributor

Hi All,


All of a sudden, all users using webmail now cannot log on the error says:
"Sorry, that didn't work.
Please go back to and try again.

And some users using outlook now are having the credential window keeps popping up, although they provided the right password.

Something has changed at MS office 365 that I don't know.

Any help/ advice would be appreciated.

Might be a temporary connectivity issue, best open a support case.



I've found the culprit just now, it was SSL which doesn't match the thumbprint.

Thanks for the help anyway.

Have a nice X-mas
