Outlook - Certificate has been revoked

Hi,

We're experiencing the same issue as @Amir Jafarian 

Fully patched msi version of Outlook 2016. Connecting to Exchange online. Sporadic Digicert certificate warnings across the org. Seems to happen most commonly when waking a device from sleep. I'd agree it looks like issues checking the CRL but can't find the cause.

We've got tickets open with Microsoft and our proxy vendor but not getting anywhere fast. We've had our proxy solution in place for some time without issue and nothing has changed.

I'll post if we find anything.
