First off, I will apologize for cross posting. This was originally posted in a Lync forum, but I think it might be more of an Exchange question. ( http://social.technet.microsoft.com/Forums/en-US/d040894d-a09f-46ae-ad1c-adcc82d3a944/exchange-200720102013-um-coexistence?forum=ocsvoice )
We currently have an Exchange 2007/2010 environment in production along with Lync 2010 (UM provided).
I have installed a number of Exchange 2013 server and will be migrating ( over a LONG time ) to the new system.
In the meantime, I need to have all services co-existent across all three Exchange versions.
It looks like I have everything working now except UM for Lync 2010.
I tried adding the Exchange 2013 servers into the existing 2007/2010 dial plan and am having issues.
Here is what i did.
( Following the steps on
http://technet.microsoft.com/en-us/library/dn169227(v=exchg.150).aspx )
My actions, step by step, following that article.
- Step 1 – Done
- Step 2 – Did nothing. No custom announcements
- Step 3 – Certificates set
- Step 4 – UM Startup set on CAS
- Step 5 – UM startup set on MB
- Step 6 – Noting done. Dial plan already exists
- Step 7 – Nothing done. UM IP gateways already configured
- Step 8 – Nothing done, No hunt group needed
- Step 9 – Nothing done, UM Auto Attendant already configured
- Step 10 – Nothing done. UM Mailbox Policies already in place
- Step 11 - Nothing done. Wanted to verify UM still worked for 2007/2010 MB users before testing Exch 2013 users
- Step 12 – Same as step 11
- Step 13 – Nothing reasoned that Lync is pulling UM information from AD
- Step 14 – Nothing. Leaving in co-existence
- Step 15 – Nothing. Leaving in co-existence
Waited an hour for replication and found that Lync now fails to send voice mail to my Exch 2007/2010 users. (did not test 2013 users)
Lync fails to send calls to voice mail, giving me events 45024 and 44022 on the Lync FE stating that Lync could not connect to the Exch 2013 MB servers and the attempt to connect to UM failed.
I dis-associated the dial plan from the Exch 2013 CAS and MB servers, waited an hour, and VM started workign again for my 2007/2010 users.
Does ExchUCUtil.ps1 need to be rerun on the Exchange 2013 servers?
This utility creates the UM IP Gateway. Does it create for Exchange in general, or does it create it for specific versions of Exchange?
In the Exchange 2013 EAC, I enter the Unified Messaging / UM IP Gateways screen and see the UM Ip Gateway links that are in use for by Exchange 2007/2010 and was hoping that that would suffice for Exchange 2013.
Is there anything else I missed?
If I do need to run ExchUCUtil.ps1, and after reenabling the dial plan in Exch 2013 VM fails. How does my backout plan change? Do I need to run ExchUCUtil.ps1 on one of my legacy Exchange servers again?
Thanks!
Tom
