- 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 🙂
You should have red error message when launching exchange powershell.
You Can copy paste this error on Google.
Aldo, what is error message ?

I did the renewal process, as my Auth cert was expired.
For me both OWA and ECP are not working.
After doing everything, it still doesn't work.
I suspect I need to wait 2 hours until GMT "reaches" my local timezone.
From the other posts I suspect that certificate checking is done in GMT and not the local timezone.
