I've had this problem. It had to do with office SP1. While I never fixed it, I got around it by removing office SP1 as I was unable to duplicate the problem on machines w/o office sp1. One of these days I'll come across the proper solution and put back SP1 Joshua Genin Director of Information Technology Manhattan GMAT * 212-721-7400 X- 25 / 800-576-4628 www.manhattangmat.com *GMAT is a registered trademark of the Graduate Management Admission Council, which neither sponsors nor endorses this test preparation service. -----Original Message----- From: Johnson,Scott [mailto:sjohnson@xxxxxx] Sent: Thursday, March 03, 2005 7:55 AM To: [ExchangeList] Subject: [exchangelist] RE: The messaging interface has returned an unknown n error. http://www.MSExchange.org/ I have tried it both ways.

I have a user trying to print a specific day from another users calendar. When she does this, she gets the message "The messaging interface has returned an unknown error. If the problem persists, restart Outlook." Well, she restarts and the same message comes back. She can print weekly or monthly calendar events without any problems. She is running Outlook 2003 attaching to an Exchange 2003 server. I couldn't find anything on Microsoft's website that addresses this issue.
