MS Exchange Event ID 9175 Error

cmaohio asked
Medium Priority
Last Modified: 2012-05-06
I have a setup with one Back-end Server and two Front-end severs all running MS Exchange 2003 sp2.

I was reading that I shouldn't mount the stores on the front-end servers so i right-click the information stores on those two and dismounted them and then chose "Do not mount this store at startup".

Now ever since then I'm getting these event ID's 9175 every 30 seconds! The system is wanting to mount the store but it can't be. Why does it continue to bother me? How can I stop it!

Error codes on their own are useless. You need to post the full text.
Furthermore it is not always the case that you shouldn't mount the stores. If the server is receiving email as well as just doing HTTP traffic etc then the stores need to be mounted.

The complete Error is:

Source: MSExchangeSA
Category: MAPI Session
Event ID: 9175

The MAPI call 'OpenMsgStore' failed with the following error:
The Microsoft Exchange Server computer is not available.  Either there are network problems or the Microsoft Exchange Server computer is down for maintenance.
The MAPI provider failed.
Microsoft Exchange Server Information Store
ID no: 8004011d-0526-00000000

The two severs do not receive e-mail via SMTP unless you mean having it handed off to them to send e-mail out. That is it. They receive mail from the back-end for sending out. They are also OWA servers.  Incoming mail comes through a barracuda spam firewall.

If email is going through the server, in or out, then the stores need to be mounted.

That would account for the errors.

You can only dismount the stores if the server is being used exclusively for http traffic - so OWA, OMA, EAS or RPC Over HTTPS.

Ah, okay, I guess what I read before was wrong information. Thanks so much!
