[otrs] Emails via IMAP is fetched by server but never gets inserted to SQL(OTRS)

Hi, I have installed OTRS successfully and setup an IMAP account towards an Exchange 2003 server. This worked fine for a while but then stopped working. The IMAP service is running on the Exchange server. I've installed wireshark (network analyzer) to see that the email is fetched via IMAP protocol into the server when the cronw is running. I can see that it finds the new email, fetches it, deletes it from the Exchange server, but it never gets inserted into the SQL database. Anyone have any idea where I can search for the error? Server: Windows 2003 Server SP2 OTRS v. 2.3.4 CronW (for fetching emails) (uses crontab.txt) Best regards Daniel Tangen
