#550 5.6.0 STOREDRV.Submit: The Microsoft Exchange Information Store service reported an error. The following information should help identify the cause of this error: "MapiExceptionPropsDontMatch:16.18969:48000000, 17.27161:0000000022260000000000000000000000000000, 255.23226:00000000, 255.27962:22000000, 255.27962:09000000, 255.27962:08000000, 255.31418:0A000000, 4.18457:19050000, 0.21761:00000000, 4.29953:19050000". ##

The Exchange 2007 troubleshooting assistant yielded no answers as to the problem nor is there any reference in the Exchange Server event logs.

After some investigation it seems this particular problem is isolated to the particular email the user is attempted to forward – it has one attachment. Forwarding the email without the attachment works and saving the attachment from the original mail to a local drive then reattaching it to a new mail also works.

Running performance monitoring shows a high number of pages/sec on memory and the Exchange Service. The server has 32GB and a 35GB paging file although the recommendation is 48GB – I have upped the paging file to see if that bring the number of pages/sec down. The recommendation for paging file, with memory above 8 GB, from Microsoft is the amount of memory plus 10 MB or the amount of memory multiplied by 1.5. On the memory note it is worth mentioning the recommendation for memory for an Exchange Server 2007 with multiple roles is 8 GB of memory with with ideally an additional 5 MB (between 2MB for light users and 5MB for heavy users) per mailbox up to a maximum of 32 GB per sever. For more information on how memory and the page file are affected by Exchange 2007 see the article Understanding Exchange 2007 Memory Usage and its use of the Paging File.

My current thinking is the problem could have initially been caused by back pressure on the Exchange Server however I also plan to take the mail stores offline and run the Exchange utilities on them to be sure no corruption has crept in.

I will post more updates on this issue as I find them.
