After running the Microsoft Remote Connectivity Analyzer, we received a connectivity test fail while testing the certificate:
Testing the SSL certificate to make sure it's valid.
The SSL certificate failed one or more certificate validation checks.
Certificate trust is being validated.
Certificate trust validation failed.
The Microsoft Connectivity Analyzer is attempting to build certificate chains for certificate CN=...
A certificate chain couldn't be constructed for the certificate.
Additional Details
The certificate chain has errors. Chain status = NotTimeValid.
Any idea on how to fix this?
Hello,
Is that certificate expired?
Thanks,
Manu
We had a certificate expire a few months ago, and we replaced it on the ad fs servers.
The one we are using right now should be valid until 2022.
Is is possible the Exchange online is still using the old one?
Hi,
Please check Using Powershell
Get-MsolFederationProperty -DomainName "your domain name"
If it shows expired certificate, you can update it as follows:
Update-MsolFederatedDomain –DomainName "your domain name"
And check again with the first cmdlet

Thanks for the help so far.
