Hi Guys, Having recently installed a new copy of Exchange Server 2003, I keep getting this error in the event logs: Event Type: Error Event Source: MSExchangeSA Event Category: MAPI Session Event ID: 9175 Description: The MAPI call 'OpenMsgStore' failed with the following error: The attempt to log on to the Microsoft Exchange Server computer has failed. The MAPI provider failed. Microsoft Exchange Server Information Store ID no: 8004011d-0512-00000000 The exchange infomation store is running. I get this error when I try to mount the exchange store: An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both. ID no: c1041724 Exchange System Manager I have tried all the KB articles I can find, they're still not working. Thanks

If your exchange 2003 server is running perfectly then this error can be ignored . it describes about a failed MAPI session .

Hi When you use Microsoft Exchange System Manager to mount a mailbox store, you may receive error c1041724: An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both. ID no: c1041724 Exchange System Manager The following event ID messages may also be logged in the Application event log: Event Type: Error Event Source: MSExchangeSA Event Category: MAPI Session Event ID: 9175 Description: The MAPI call 'OpenMsgStore' failed with the following error: The attempt to log on to the Microsoft Exchange Server computer has failed. The MAPI provider failed. Microsoft Exchange Server Information Store ID no: 8004011d-0512-00000000 -or- Event Type: Error Event Source: MSExchangeIS Event Category: General Event ID: 9546 Description: Failed to create the Event Registration Mailbox for Database First Storage Group\Private Information Store (servername). Error - 0xbf69. -or- Event Type: Error Event Source: MSExchangeIS Event Category: General Event ID: 9519 Description: Error 0x80004005 starting database "First Storage Group\Private Information Store (servername)" on the Microsoft Exchange Information Store. CAUSE This behavior can occur when a System mailbox object that is created for this mailbox store exists in the System Objects container. When you try to mount the mailbox store, an Exchange 2003 computer may create another object. Only one System mailbox object can exist for each mailbox store. RESOLUTION To resolve this behavior, delete the System mailbox object that exists: 1. Start the Active Directory Users and Computers snap-in. 2. On the View menu, click Advanced Features. 3. Locate the Microsoft Exchange System Objects container, locate the System mailbox object that was created for the mailbox store that you are trying to mount, and then delete it.
