Hey Guys, I am using exchange 5.5 sp4. Following is the error i am getting in my event log. Can any one please help Event id - 12006 Source- MsExchangeIS Category - Content Engine Error 80004005-F2000233 occurred while processing message <RGryWtIIZ00015462@server.Meridian-tech.com> from 'postmaster@Meridian-tech.com'. The archive filename is 'MSYD1CN9'. Thanks in advance.

Are you getting a LOT of these? This may be an SMTP message that the Ex 5.5 server cannot interpret. Look in the IMS Archive folder for the MSYD1CN9 file, rename it to MSYD1CN9.EML and see if you can open with with Outlook Express (If I remember correctly, you can do this). Does it look like a valid SMTP message?

What is the version of Store.exe file?
