Here is something I'm seeing a lot in my event viewer:\n\nProduct: Exchange\nEvent ID: 9175\nSource: MSExchangeSA\nVersion: 6.5.0000.0\nMessage: The MAPI call 'value' failed with the following error: error code\n\n\nThat even ID 9175 is all over my event viewer - probably about 20 instances\nof it right after I reboot the comput. I think I've narrowed down the\nproblem to - I can't mount my Mailbox Store in my First Storage Group for\nExchange.\n\nI also get this in my event viewer:\n\nProduct: Exchange\nEvent ID: 455\nSource: ESE\nVersion: 6.5.0000.0\nMessage: process name (process id) file nameError %5 occurred while opening\nlogfile error code.\n\n\nI think both of these events - at least the problem that reports these event\nID's has caused my exchange server to just die (well, more precisly, nobody\nin my company can send/get email).\n\nA lot of what I've read so far says to make sure store.exe is running as a\nservice (it is). Check permissions on certain folders (permissions are all\ngood) - but right now, my exchange box is just dead w/nobody being able to\nconnect via outlook or send/get email. Yesterday it was working great -\ntoday, just walked in to work and poof - stops working. Nobody has played\nw/the exchange box - I'm the only person in the company with access to it.\n\nI figured there was a problem when outlook 2003 was reporting: Task\nMicrosoft Exchange Server reported error (0x8004011D)\n\n\nDoes anyone know what's going on?? Thanks in advance all.\n\n\nI also read this page and all the links - but nothing helped:\n[URL]http://support.microsoft.com/search/default.aspx?Catalog=LCID%3D1033%26CDID%3DEN-US-KB&Product=OFF2003&LN=EN-US&SD=OFFN&Query=0x8004011D[/URL]\n\n\nThanks.
