- Ok i found solution. Use this to create new certificate https://docs.microsoft.com/en-us/exchange/troubleshoot/administration/cannot-access-owa-or-ecp-if-oauth-expired
And after creating the certificate you must wait like a hour or more for changes work. Restart dont change the wait time 🙂
Nikolas_Athanasakis Hi i have the same problem it started today at 2 am on our server. We can't log in to owa and ecp. I tried to create new auth-Config certificate becouse i couldn't display the thumprint but it didin't work too. im thinking about cu 10 bot not sure if this will fix problem.
- thanks god.
Worked for me too and take 2 hours and half.

Restart dont change the wait time 🙂Hi Asterofus may you please share the working document for the link you provided here it doesn`t seem to work and after reading this conversation I think it`s what I need for my problem today. Thanks in advance.
- thanks for this!! After applying the change, I waited a few hours for it to work, even if you reboot it doesn't change .. it needs a few hours, and now everything is working.
thanks Asterofus - Mein Got. None of the above fixed it until I changed server time to GMT +0. And this was a suggestion from Prem Support as well. Madness.
