Hi, I am attempting to search a long list of mailboxes that have email sizes greater than a specific size but I have a few questions. First, I do not want to export the email. I want to copy the email that is found to be the size or greater into another email account. Can I do this through the search-mailbox command or is there a better command? Second, there are a LOT of users I have to do this against. Instead of runnig the command below for each person how can I run the powershell script against a txt file or some other listing of the email aliases? search-mailbox -identity 'username' -SearchQuery System.Size:>100kb Thanks, Exchange_Dude

Hi, >>First, I do not want to export the email. I want to copy the email that is found to be the size or greater into another email account. Can I do this through the search-mailbox command or is there a better command? Of course, you can use Exchange Management Shell cmdlets or the ECP to create a multi-mailbox search. Search results can be copied to the discovery mailbox selected as the target mailbox for the search.

Instead of runnig the command below for each person how can I run the powershell script against a txt file or some other listing of the email aliases But Multi-Mailbox Search doesn't support regular expressions. So you can’t do it with advanced query syntax.
