We are in the process of taking over a small firm and proceeding with manual migration of mailboxes from this firm , currently we do not have full access to their environment and having a hard time depending on admins of their organization dealing over to exporting mailboxes and then importing them back to our exchange environment,  my idea is to rather provide a executable or batch script to user's of their organization get their mailboxes exported out directly from end users  so that we do not have to depend on remote organization's admins for every single user out there . is there a batch script or some executable code that end users can run to have their mailbox exported out direct

Hi

You would still need access to export them. your batch file would need to be run to include powershell snap-ins etc.

The best would be to grant you the relevant rights to export mailboxes to pst.

we do have access planned out for migration day itself , but my idea was to get this completed prior as a pre-migration task .. any suggestions apart shall be highly appreciated
