Amir Jafarian that looks like either a problem communicating with the CRL or there might be another issue with your system or an intermediate network device (like a proxy). Since you are connecting to Exchange Online you can raise a support ticket with Microsoft for troubleshooting assistance. You can also try running diagnostics with the SARA tool (https://diagnostics.outlook.com).
Other posters are complaining of certificate popups for on-premises Exchange server environments, which could be an entirely different problem with their server or certificate configuration.

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.
- HapJun 07, 2017Brass ContributorJust a quick note. We have the same issues, but no proxy in between. Doubt it is related to your (forward) proxy, or did you mean reverse?
