i have Outlook 2010 and 2007 Client PCs that are not deleting emails from the server.
Their accounts are now as big as 4Gig on the server but all the emails on the server are also in their outlook clients on their PCs. im not using email Quotas.

They do not receive duplicate emails as what others in the forums where saying.
All other users have outlook 2010 and 2007 Clients but their server accounts have nothing since im using POP3.

Im using ZCS OpenSource 6.0.10 on CentOS 5.4 64bit
