hi I would like to renew the self-signed in my exchange 2007 environment. Please let me know what permission required renewing the certificate. waiting for reply

Hi, You can renew certificate with permission Exchange Server Administrators on server where you want to do it. The Exchange Administrator role is essentially the same as the Exchange Full Administrator role although this role does not give the ability to grant permissions to other Exchange administrators I will advise you to go ahead with below detail for more detail about Exchange 2007 permission model http://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/exchange-2007-permissions-and-roles-part1.html Anil

Hi, I think the permission could be the same when you run new-exchangecertificate: To run the New-ExchangeCertificate cmdlet, the account you use must be delegated the following: Exchange Server Administrator role and local Administrators group for the target server To run the New-ExchangeCertificate cmdlet on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.
