When I limited the size of the PST in my lab the mailbox stopped receiving email, but Exchange did not send a "Mailbox Full" email to the sender. Trying to send an email gave the user a "Your Mailbox is Full" message.
Looks like I've done something wrong in my testing since the OST of others wasn't affected. ________________________________ From: William Lefkovics [mailto:will...@lefkovics.net] Sent: Monday, March 23, 2009 12:36 PM To: MS-Exchange Admin Issues Subject: RE: OST's & PST's >> However, this also affects OST files.

Phase one will be disabling the creation of New PST's, disabling Archiving AND not allowing email to be added to existing PST's. Using Outlook11.adm in Policies I can gray out the ability to create new PST's, disable Archiving and I can set the maximum size for existing PST's to 1 Meg, which effectively keeps users from adding emails to their PST's. However, this also affects OST files. Since we are using Caching to allow users the ability to use Junk E-mail, this solution isn't acceptable. (And yes, I don't like Caching...not my choice!) Is there a way to lock down adding email to existing PST's without also locking down the OST files? Have I missed something in my research? Larry C.
