    Yes I thought of the same thing. I would think they would mention that in the current build release though...   :(

    We have not run any updates on our 2007 exchange server in about 5 years.  Anyone else in that same situation?  I'm wondering if it could be related to root certificates?

    We have not run updates recently either but the root cert for my CA is valid from 2009-2038. It must have been installed for years without issue.

    Unless it's been revoked and I'm the last to know.

    We're using DigiCert. One server is affected, the other one - not yet, though both are configured the same.

    We are using a Comodo certificate and have and have not run any updates on our 2007 exchange server in about 5 years.  Anyone else in that same situation?  I'm wondering if it could be related to root certificates?

    We have another 2007 mail server on a different domain that uses a GoDaddy certificate and no issues that I am aware of.

    If it's spreading with a lots of users affected, I hope that we can expect a resolution from Microsoft, in despite that Exchange 2007 is obsolete.
