Certificate configuration between UM and HUB to avoid error 1423 RRS feed

  • Question

  • Hi everyone,

    I have two physical exchanges servers:

    -> One with hub transport (esx-webmail.xx.lan) with this own certificate for smtp service

    -> One with UM (exum.xx.lan) with this own certificate for um part

    The Um works fine with Lync but doesn't transfer voice mail on the hub. And I have the errors 1423 and 1446.

    I check the different solutions:

    -> SETSPN.EXE –l  all is ok

    -> New connector for UM with auth exchange --> ok

    -> Fqdn for hub -> ok

    I just have a question for the last part, the certificate. It's not clear if it's a single certificate with differents san that I have to export from UM to HUB, or it's a single for each...

    If someone has a solution, it will be very nice. I'm working on it for 2 days...
