Hi
In my school we use sharepoint and 365. For 2 days I have staff complaining they are getting a warning saying certificate revoked when trying to log in via sharepoint, or login.office.com.
Here are some points I have assertained.
1 user was working fine then got kicked off and couldn't access it again, logged in as supply and it worked. He tried another machine and it worked.
1 user works in a few rooms, does not work in a few rooms. In the rooms it works for her, another member of staff could not get in.
1 user (at least) could not access from home.
Didnt work for 1 user, so I removed all saved profiles on that machine, next login it worked, but didnt for another user.
Some students are fine, some are not.
restarted firewall and all certificate servers, certificates are not expired.
I am stumped. It is causing so many T&L issues.
Anyone who has had similar please help?
