Hi guys!I have some strange problem with our new Exchange 2007 Server I couldn't find a solution for by myself yet.We are currently trying to migrate the usermails from our old linux- server using linux- based "IMAPsync".Syncing works fine, until there is a mail that comes with an attachment larger than 60 kb. As soon as such a messages is being synced, the process stops and a warning in the event log in Windows appears: Code Snippet Application: MSExchangeIMAP4 Code Snippet An IMAP client has specified a literal whose value (586524) is larger than the configured maximum of 60416.User: .........Client IP address: ........So, it seems like, there is a limit of 60 KB somewhere deep inside the configs, but unfortunately, I cannot find it.I appreciate any help on this!!Best regards from GermanySascha

Change the maximum receive size in your hub transport under both server and org config. Then you have to restart the IMAP Service. It will use the larger value
