Stop users from connecting to Exchange 2007

Hi all,
I'm busy with an Exchange 2007 mailbox migration and I want to prevent users from connecting to Exchange. I do however want to keep the critical Exchange services running required for the migration. What services do I need to stop on the Exchange server to prevent Outlook connecting to Exchange 2007? Thanks!

You could try removing the FullAccess right to the user "SELF" for each mailbox using exchange management shell. and add it back after your migration is finished.

To remove for every mailbox: Get-Mailbox | Remove-MailboxPermission -User "SELF" -AccessRights FullAccess
To add it back to every mailbox: Get-Mailbox | Add-MailboxPermission -User "SELF" -AccessRights FullAccess

Although if you migrate from exchange 2003 to 2007 this wont be possible, but 2007 to another 2007, this will work.


While that may work, unless the store is bounced immediately after making the change, it will be two hours before the change is in effect. Then when it is undone, it will take another two hours to be fully active - again unless the store is bounced to get the change to take effect.
