Very annoying IMAP problem (cyrus + Outlook)

[Denis BUCHER]

Hello,

We have 50 people using Outlook on our IMAP cyrus server. It's
wonderful : fast, efficient, no problem, easy...

But for 4-5 days I have a strange problem only on one PC :
* Outlook has to reconnect to the server every 5 minutes because of
"Fatal error: word too long".

As far as I understand, the cause of the problem is :
* "Outlook is sending either a token or quoted string that is longer
than 8K bytes."

But how could I correct this problem either in Outlook or cyrus ???
* Can I simply delete the "offending" email in Outlook, but how to
find which one ?

Thanks a lot in advance for your help !
