Probably an easy question for most of you

We are running exchange 2003 stnd. in our company. I have a question I was hoping to have some help answering.

Here goes:

A user gets a daily email from a news agency with a 2MB attachement. Everyday, he forwards that message to his secretary for printing and then deletes it. So he has a copy of that message in his sent items and one in his deleted items. Does that count as 4MB now since there is two copies? Or is exchange smart enough to only have one copy of an attachement no matter how many folders it resides in.

Thanks

Thanks

It will only take 2MB on the server.

From Microsoft's website...
"If a message is sent to one recipient, and if the message is copied to 20 other recipients who reside in the same mailbox store, Exchange Server maintains only one copy of the message in its database. Exchange Server then creates pointers."

It will count as 4MB in any mailbox quota you have set up however.

The concept is called Single Instance Storage - google it.

If a user received a message, and then forwards it, those are two different messages. SIS doesn't apply. It's a 4MB hit on the mailbox size.

To clarify: Inside the Exchange database it takes up 2MB. In his quota / mailbox size, it is listed as 4MB.

Set up a rule to forward it and hard delete it then it doesn't matter. Or more obviously get the inbound email address changed to her address...

Pat's correct on this one.

The deleted email is the original. The one in the 'Sent Items' is classed as a new message (sender and recipient are different).

So both emails will take up 4mb of storage and 4mb of mailbox quota.
