Exchange 2013 cu10
it could be related or not. not sure. but i have another thread on the same certificate https://social.technet.microsoft.com/Forums/en-US/431ec4b6-8a81-461b-b22a-76ab3599626d/cas-uses-invalid-certificate-error?forum=exchangesvrgeneral#55171a03-28cb-48b6-a774-27b1c28141bc
whenever users would start Outlook, they are prompted by this popup box:
but on CAS01 there is no such prompt.
CAS01 and CAS02 uses the same SSL certificate. certificate from CAS01 was exported and imported to CAS02. IMAP, POP, IIS, SMTP services are enabled for both CAS server's certificate.
now looking at the last line regarding the name, should i have included the CAS02 in the SAN? from my readings it is not recommended so how to fix this problem then?
