Hello, and thanks in advance for your time. I currently have Exchange 2000 Server running with a Blackberry Enterprise Server. Some months ago I learned of the secret mailstore 16Gb size limit. Well, I have come to a point where pruning the database and forcing users to dump mail is no longer effective. I have just ordered the Exchange 2000 Enterprise server, which has no mailstore size limit. The question is this: Is there anything I need to be aware of in upgrading from 2000 to 2000 Enterprise? Has anyone else done this? Shouldn't I just be able to copy the public and private stores into the appropriate directory after upgrading the product? Thanks for any information I can get on this...
