alrite...i did the rebase tool. and it went ok...it found about half of the users...with the correct time zone. and then errors list didnt have the time zone..however if you know what they are..you can just add it in..
i was actually shocked as to how easy it was ... it worked well..
now did anyone run kb926666..that was a pain.. killed my BES...only half the users were getting mail on their handheld.. and it was not the 'send as' permissions being revoked.. took me the whole day to fix it.. we needed to create a new service account.
and now it has killed some of shared resources..like to send from another mailbox...or open another users calendar... i thought i read this somewhere...but i dont remember..
i say if you can hold off on doing this update.. i would.. kb926666.. stay away... :) ....sorry Exchange team..
