Our Exchange has a UCC SAN CERT for mobile users. When the Cert expired, one of our admin deleted the Cert and purchased a new one. He did not add our local domain names to the Cert. Now, Outlook gives the error message stating the Name on the Cert does not match. The users say ok to the message and all is well until you open Outlook again (very annoying); however, the mobile users are working fine.
I have tried several of the articles on here to which you point the CAS, OAB, ActiveSync and so forth using the Exchange Mgmt Shell to the new cert; however, none have proven to resolve my issue.
Would the best solution be to get a new Cert with our local domain names added and install it?
Thank you for any help.
