We are having a challenge I'm hoping the community can help with:
Working to do a staged batch migration from SBS 2003 to Office 365. The migration tools will not connect as there isn't a 3rd party certificate in place...only the self-signed.
Question: Can we add a simple public CA certificate to the existing server in ADDITION to the in-place self-signed one? There are numerous remote stations connecting with RPC/HTTP and we do not want to break that process. We have not found any specific resources for adding another third party certificate (autodiscover.domainame.xxx) to IIS for this purpose. Is it possible and can you offer any direction?
In trying to create the CSR - the only option is to manipulate the self-signed; again we need to protect the integrity of RPC/http as it is now.
All mailboxes are moving; no federation - this is for a non-profit so resources are scarce :-)
Thank you in advance for your thoughts.
