Hi all,
not sure if anyone has experienced it, but we are getting tthis error multiple times a day when using outlook.
It says :
Outlook.office365.com
Information you Exchange with this site cannot be viewed or changed by others. However, there is a problem with the sites security certificate.
The security certificate for this site has been revoked,
This site should not be trusted,
If we dont click OK, outlook cannot send or receive emails. Sometime this window is hidden behind and therefor are not aware of it during the day.
if we click view certificate, it looks legit and everything seems to be ok. If enter OWA, we get same certificate(according to thumbprint), but there is no warning or error,
We have created a case with Exchange online team, but they say there are no error from their side and its internal network issue.
We have cleared certificate revoke list from our DNS servers without any help.
Any ideas on how to troubleshoot this further?
We use Outlook 2016 with latest updates and have all mailboxes in Exchange online.
I only have my archive mailbox attached to my outlook,
Thanks!
