Unified Messaging with Lync 2010 and exchange coexhistence 2007 and 2010 not working RRS feed

  • Question

  • We are in the process of upgrading our exchange environment from 2007 to 2010.  we installed a new UM server for 2010 UM role installed and added the dial plans that are on the 07 server to this new UM.  now for some reason we are not able to call to check voicemail from teh lync clients and also have some sort of intermittent transferring issues not sure if that is associated to the UM server.  i've tried removing the dial plans from teh 2010 um server and restarted teh services but did not fix it.

  • i forgot to run a few steps, needed to request a local certificate and assign the UM services to that certificate on the 2010 server than everything worked!  Microsoft helped out and said after everyone is migrated over to 2010 and before i remove the exchange 2007 um server to run this command then remove the server.

    Pratap:set-umdialplan -identity "name of the dial plan"

    Pratap:set-ummailboxpolicy -identity "name of the mailbox policy"

    Pratap:set-umautoattendant -identity "name of the Auto Attendant
