JavaMail & MS Exchange Server

[mark evertz]

Hello all,
we have the following problem using JavaMail with MS Exchange and Pop3.
After fetching mails from the server we want to delete marked mails (on the server).
In the documentation I read that this can be achived by calling folder.close( true );
Getting mails works, but mails will not be deleted afterwards.
Has anybody experienced similar problems and maybe knows a solution for this?
Greetings,
Mark
