Hi We are running Exchange 2007 SP2. We're going to be having a large number of users leaving our company to work for a partner company, about 300. We'll need to export their mailboxes from our Exchange 2007 system to a PST file. The mailboxes sizes are varying up to 1GB. I know there is a command to Export to PST, but I'll need to run this on multiple mailboxes at the same time. I was going to have a CSV file with the list of users, but how many maiboxes will it export at the same time? We're hoping to have the export completed over a coupleof days.

Hello Thanks.....if the list contains 300 mailboxes ,will it process only one mbx at a time? is there a way for it to export multiple mailboxes at the same time?

Hi So you think I can run an Export-Mailbox for these 300 mailboxes over a couple of nights? Couple of questions - i. Is there any where to make the Powershell window run more than one Export at a time ii. Is there any reason not to run multiple Powershell windows running on the same server running exports iii. When the export commands are running on the Utility server, will this have a neglible performance impact on the server where the mailboxes are being hosted? Or does the Utility server running the export take the performance hit? Thanks for the help

Hi You can open two or three EMS at the same time, but I am not sure the speed will go up or not. CheersZi Feng TechNet Community Support
