If you run Exchange 2007 SP1 with an antivirus program like Trend Micro ScanMail 8.0, the following event may occur in your eventlog:
Event Type: Warning
Event Source: MSExchangeIS
Event Category: Virus Scanning
Event ID: 9874
Date: 8/4/2008
Time: 8:34:47 AM
User: N/A
Computer: %
Description:
Unexpected error 0×80040109 occurred in “EcProcessVirusScanQueueItem” during virus scanning. Mailbox Database: %/cn=Microsoft Private MDB
This Warning is a known error in SP1 and you can ignore it. So far, there has not been released a hotfix for it. Maybe SP1 Rollup 4 will come with a solution (as I’m wrting this, only Rollup 3 has been released, which does not fix the problem)
Update december 11, 2008: tested by myself and one of my blog readers, Rollup 4 does not fix the EcProcessVirusScanQueueItem – problem. Maybe I was too optimistic when I wrote this post in August :(
Microsoft Release Roll up 7 but there is a BUG on it,After installing Rollup 7 Exchange Outlook Web Access is not functioning.i have remove the rollup patch then my OWA start functioning again.
