Exchange Server 2003 on Windows Server 2003. No permission changes made. 1) User from Outlook 2003 SP1, sends an email to another local Exchange user 2) Sender attempts to recall email, but is presented with a permission denied error - contact your systems administrator (me). 3) The user (like all users) has full mailbox access, read permissions and associated external account. Has anyone seen this before? Thank you, ...D
