Disable MTA service

My Exchange admin want to disable MTA service for all Exchanges, Unity UM,

Is there a reason why I cannot stop it?

For what purpose Unity uses that service?

I did it in my lab server and I get no error in EV regarding Unity only an Exchange error:

Event Type: Warning

Event Source: MSExchangeIS Mailbox Store

Event Category: MTA Connections

Event ID: 2000

Date: 06/01/2006

Time: 11:47:10 a.m.

User: N/A

Computer: BEATLES


Verify that the Microsoft Exchange MTA service has started. Consecutive ma-open calls are failing with error 3051.

Re: Disable MTA service

As far as I know that service is only used for message transport via x.400 to Ex55 servers in the site - there may be more to it than that, but I don't think so.

this doesn't have anything to do with Unity - those errors are probably the system monitor stuff - you might check under the Exchange System Manager (to to tools | Monitoring and Status | Status - right click on the server name in question and check properties) to see if the service is listed as required or something. You can remove it as a dependant service here but I'm not sure about that.

either way, you'll probably want to check with the MS folks about this, not us - this is outside the realm of Unity.


Re: Disable MTA service

One thing that does use the Exchange MTA is the Voice Gateway 2000. So if you're using AMIS, Bridge, VPIM or SMTP networking you don't want to disable this service on any server running the Voice Gateway 2000.
