Unrecognized internal error: 0x50b Error: 1025

I work in an office with an exchange server, there are 3 of us with Macs
who use Entourage 10.1.4 (everyone else uses Outlook).
We have had constant problems with our e-mails, most of which have been
solved by rebuilding the database.

We are currently recieving this error message everytime entourage runs
send and recieve:

Mail could not be received at this time.
The server returned the following error
Unrecognized internal error: 0x50b.
Error: 1025

- We are actually recieving mail ok on the whole.
- My inbox shows that there are 3 unread mails but actually there
aren't any there (nor on the server apparently)
- If my colleague clicks on a folder the folder and contents disappear
(!) and entourage crashes.

Our on-site support person doesn't seem to know anything about
Macs....
I've seen this error mentioned previously but haven't seen a solution.

Does anyone know what this is and what I can do about it?

(I've also reinstalled entourage with no joy)

Anyone?!!

I would be VERY grateful!!!

Thank you
