Outlook 2003 - The messaging interface has returned an unknown error

We have a client that was receiving the following error when trying to print a public calendar:

The messaging interface has returned an unknown error
Okay, a simple search turns up the following Microsoft KB articles, but they are not relevant: None of them applied.

Once, and only once did we get an error indicating permissions problems on the task list folder before the above mentioned error.

So, when printing the calendar view, we went to the Page Setup button, and disabled printing the tasks list.

It worked.

So far, we haven't been able to find out just where the permissions conflict is yet.

But, they are happy about being able to print out their calendar again.

Honourable mention to the following who provided the key to figuring out how to get things going again:

Experts-Exchange: The messaging interface has returned an unknown error.

MCSE.MS: The messaging interface has returned an unknown error.

I had the same message just creating a new email or replying, on our corporate email system - and followed the same journey. Your post got me to check the permissions on my Inbox and that was the problem - mysteriously, my entry as owner had gone. Even more bizarre - despite no longer having persmissions to send a new mail, it let me add myself as owner again, and after restarting Outlook, the problem was cured.

Thanks.

I was having the same issues, and repairing the OST didn't help me, but what did was just creating a new Outlook profile. Once I created it i was once again able to create emails and send/receive (which always returned the error message before)
