Hi, Here is the issue, i have a MS SBS 2003 DC with Exchange 2003 SP2.  Active Sync emails all seem to work fine, but every couple days it will stop working.  The following Events appear in the Application Logs in Event viewer:


Event Type:      Error
Event Source:      Server ActiveSync
Event Category:      None
Event ID:      3005
Date:            3/23/2011

Description:
Unexpected Exchange mailbox Server error: Server: [yyyy.xxxx.local] User: [marc@xxxx.ca] HTTP status code: [503]. Verify that the Exchange mailbox Server is working correctly.

and

Event Type:      Error

User:            N/A
Computer:      Server
Description:
The MAPI call 'OpenMsgStore' failed with the following error:

The MAPI provider failed.
Microsoft Exchange Server Information Store

What is wierd is that simple restart of Exchange System Attendant (it automatically restarts Information store, MTA Stacks, POP3 Connector.  I also restart IIS and all works fine for a couple days.  

This all started a few weeks ago when my C drive on server ran out of space (logfiles).  Please help.

Do you see any other events in the Application Log regarding the size of the Mailbox store? Prior to Exchange 2003, you could only have a store up to 18GB in size. You may be hitting that limit if you did not increase the size of the store after installing Exchange 2003 SP2. Here is an MS article that explains how to increase the limit,

And another article that gives some more complete information on the 18GB size limit issue,
