Unity Conn 8.5 SU1 unified messaging

[panjwani80]

All,

I am building a new unity connection 8.5 cluster with single inbox integration with exchange. Current exchange enviornment has mixture of 2003 mailbox and 2010 mailbox (we are in a process of migrating mailboxes from 2003 to 2010 which could take few months). After reading thorugh unified messaging guide for unity connection 8.5 i think we have following options

First Option: Search for Exchange Servers (Preferable):

1) Create ONE (or two? one for each exchange server?) Unified Messaging Services Account in AD

2) Exchange 2010: Assigning the Application Impersonation Management Role to Unified Messaging Services Accounts AND Remove EWS Limits for the Unified Messaging Services Account

3) Exchange 2003: Granting Permissions to the Unified Messaging Services Account AND Enabling the WebDav Service on Exchange 2003 Servers

4) In Unity Connection configure Unified Messaging Service to "Search for Exchange Servers"

Second Option: Specific Exchange Servers

1) Create ONE Unified Messaging Services Account in AD for ALL exchange 2010 servers AND Create ONE Unified Messaging Services Account for EACH exchange 2003 server

2) Exchange 2010: Assigning the Application Impersonation Management Role to Unified Messaging Services Accounts AND Remove EWS Limits for the Unified Messaging Services Account

3) Exchange 2003: Granting Permissions to the Unified Messaging Services Account AND Enabling the WebDav Service on Exchange 2003 Servers

4) In Unity Connection configure Unified Messaging Service to access "specific exchange server".

The benefit of first option is when mailbox start migrating from 2003 to 2010 unity connection will automatically detect the changes.

What I would like to know if we go for first option and search for exchange servers, then do we need to create TWO Unified Messaging Services Account in AD (one for exchange 2003 and one for exchange 2010) OR can single Unified Messaging Services Account in AD can do the job??

Thanks

Hello,

I did this yesterday. You only need one account. The tricky thing is that the authentication needs to be the same for both Exchange 2003 and Exchange 2010. We are using 2003 and 2007 at the moment and what I am finding is that the 2003 server is set up for HTTP auth and the 2007 cluster is set for HTTPS. We tried changing 2003 to use HTTPS instead but I can't get Unity Connection to link up with it that way. So the way we ended up setting it up was 2 Unified Messaging services in Unity Connection. Both use the same account and are set to search for Exchange servers. Both are using the same AD service account. The only difference is that one of the services is set for HTTP auth (for Exchange 2003) and the other is set for HTTPS (for Exchange 2007). Unfortunately, this means if we migrate small groups of users to Exchange 2007, we need to manually change them to the Unified Messaging service with HTTPS auth. If we were able to do all the users in one shot, it would be as easy as just changing that option in the Unified Messaging service they are already assigned to. I tried to see if we could use bulk edit to make the change but the Unified Messaging option is greyed out...

HTH and good luck!

Thanks James much appreciated. In my case 2003 and 2010 exchange are setup for HTTP so I think I can get away with one unified messaging service account.

Cheers

Hi Guys, Im getting errors on HTTP with 2003.   When I test in the Serivce account setup, everything passes with flying colors.  When I go to a subscriber, and do a test for UM, i get the user@company.com fails and with "Null".

Any tips on this?  I have not doubled checked with the Exchange team IIS is configured correctly yet.... but that is my next move.

Thanks!

I'm getting the exact same message as Tommy when testing the Unified Messaging of a subscriber. If you get any insight, please reply back. We're using Exch

ange 2003 and Connection 8.5.1SR1.

So I see I the log files on Exchange that the account Im using is in fact logging in successfully when I run the test for UM Service. But when I run the test for my UM Subscriber and hit test, it fails. It seems like on the Subscriber test, its not using the correct account or something.

I get this error: CsWebDav/CsWebDavMbxClient.cpp:3193]: HTTP request failed with error: Bad response from server, HTTP code returned: 401, HTTP status code: 401, for WEBDAV URL:

Does WebDav not like my service account Im using?

Hello Tommer,

Were you able to resolve this issue?

I'm having the exact same problem and I see you had this a while ago.

Any advise would be really appreciated!

Hi Tommer,

According to microsoft support, seems like the user account has to be activated by logging in one of email client.

See URL below for detail and hope it is useful to your issue
