what happens if i forget to run setup /preparelegacyexchangepermissions
I followed PeteNwtLive http://www.petenetlive.com/KB/Article/0000234.htm and there is no mention of setup /prep and I did not run these steps. Can I run them after the fact? Can I uninstall 2010 and start over? What do I do now? I migrated one user and tested. I can receive but not send in Exchange 2010.
