All, We have disable "allow auto replies" in Default of remote domains (Running Exchange 2007). Due to some reason, we need to enable for some mailbox. Possible to enable for some mailbox ?? Not for all. thanks Keith

Hi Keith, Yes you can have different OOF Setting for users and the setting is controlled by the parameter -ExternalOOFOptions By default, all users are allowed to sent an external OOF so what you need to do is to change the setting on those users that will not be allowed to send external OOFs. For users that are not allowed to send external OOF Set-Mailbox USER -ExternalOOFOptions InternalOnly For users that will be allowd to send external OOF (Default Setting) Set-Mailbox USER -ExternalOOFOptions External Martina Miskovic

Hi Keith, If you want to control external OOF capabilities at a per-domain to meet your needs, I'm afraid you cannot do that. For more information, please see: Exchange Server 2007 Out of Office (OOF) http://blogs.technet.com/b/exchange/archive/2006/10/06/3395024.aspx Please remember to mark the replies as answers if they help and unmark them if they provide no help.

By Company email policy to restrict user to using auto reply to external by rule. Above solution look for the OOF, Is possible to grant the permission to a user ?? Hi Keith, Do you mean you want to restrict auto reply created by Outlook rule? If yes, you can try to use Transport rule. Please see this similar post: Allow Automatic Replies for several users only (Exchange 2007) http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/75dc37a8-f89c-47e6-af2f-110101e07e4bFrank Wang TechNet Community Support

Frank, Yes, correct but we have over 30000++ mailboxes and 4 Transport server. If I set the transport rule for scaning each mail, will it slow down the mail transfer performance ?? thanks

Hi Keith, You don't need to worry about performance too much for a single transport rule. As I know, Microsoft recommended a maximum of 1000 rules in Exchange 2007.Frank Wang TechNet Community Support
