We've got several other policies. Only one of them is an e-mail address policy, but it doesn't have FaxMaker either. So I tried preparing AD again and got the same error. What gives? Thanks.

Ah yes. I forgot to mention that I have seen that. I looked at each of our recipient policies and there are no disabledGatewayProxy entries.

Ah yes. I forgot to mention that I have seen that. I looked at each of our recipient policies and there are no disabledGatewayProxy entries. Hi mhashemi, Do you mean there is no disabledGatewayProxy Attribute displayed, or the value of disabledGatewayProxy is <Not Set> ? If the former, please clear "Show only attributes that have values". And if you add the FaxMaker( ESM -> Recipients -> Recipient Policies -> Default Policy -> Properties ) again, can you see the value in ADSIEDIT.MSC? If yes, please try to remove it as the KB said.
