Hi, Is it correct that the 2007 mailbox server role caches AD permissions and refreshes every 2 hours? We have an environment in which Send As permissions need to take affect almost immediately. Thanks, Rudi

yes see below. http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/5ad3f5ca-9e44-4dcc-bda6-7dbba97f52e7Sukh

Hi Rudi, Yes, The Send As permission is not granted until after replication has occurred. Replication times depend on your Microsoft Exchange and network configuration. To grant the permission immediately, stop and then restart the Microsoft Exchange Information Store service. You can know more clear from these: How to Grant the Send As Permission for a Mailbox http://technet.microsoft.com/en-us/library/aa998291(EXCHG.80).aspx Needed to reboot Exchange for updated mailbox permission to take effect http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/bd3f0b5b-5fe8-457a-904f-2d34b8c057b1 Thanks, Evan Liu TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

If you want to use this function for temporary purpose, then you can create a Domain Admin account, will have immediate effect on send as permission and can share the domain admin account to user temporarily, who needs to send mail as SEND AS. Advantage: No need to restart the server or restart IS (no need to wait for >120 min) Disadvantage: you need to change the Domain Admin account password, every time you share with user. ( you can manage this by simply disabling the account will do the job ) Hope this helps. Satish Mekala satish21267@gmail.com
