Q: How do i do this ->"To actually perform the rebase you must have an account with send as and full mailbox access to each mailbox."
A: The VBScript will give your account FMA & SendAs. For exporting the time zone data you can run it as a regular exchange admin, OR go into ESM and grant your account (which you ran the VB script versus) "Administer Information Store" privileges on each MDB.
