Hi Guys I have given a user send as and full access permissions to 3 domain users, the send as permission has since stopped working, she still has full access to the mailboxies. I set the permissions throught the exchange managment console (exchange 2007) the permissions are still applied when i check in the emc and also in the security tab of each user in AD. I belive it is something to do with the Default global address list, it only shows four accounts in outlook but all accounts in owa. i'm showing some errors on the sbs.

Hi This is SBS 2008 which is running exchange 2007 v08.03.0083.000 the oab is distrubution is set to sbs defaults which is enable web based distribution from the sbs web applications vitrual directory and also enable public folder distribution is ticked. lots of space! basically if you set up a user with a new outlook profile the get the full GAL if you then download the GAL you end up with address book with only a few entries which in turn breaks send as!. i have created a new oggline address book and made it default this made no difference! Regards Justin

Hi Justin, In my opinion, the OAB issue and the sendas permission are different from each other. Could you please test the sendas permission through OWA and outlook, what is the result, what is the error? Regards!

This error was resolved by recreating the default OAB and restarting iis.
