Auto replay from external email not working


When I'm setting my user as out of office, the automatic replies are not working for external recipients (outside of company). Internal users (company users) receive OOF notification.

I'm using smart host in sender connector configuration (SMTP server of internet provider) to deliver emails.
I'm using Exchange 2013, when i'm using the MX record associated with recipient domain the external recipients are receive OOF notification.

Any idea?

When you open the EMS run the following command...
Get-RemoteDomain | fl

Open in new window

Make sure that -AutoReplyEnable is True and also make sure that -AllowedOOFType is External.

If it is not you can use the below command to configure this. Exchange has these settings disabled by default for security purposes.

Set-RemoteDomain -Identity * -AutoReplyEnabled $True -AllowedOOFType External

Open in new window

The above command will set this option for all domains. If you want to specify specific domains you need to change the "*" to the domain name.

Sounds like your smart host doesn't like your OOF messages. Ask them if they have a quick solution, otherwise you might have a problem.

Hi Kimputer,

I also thought like you said, do you think there is another possible way to fix it without ask them(maybe some serivce that can handle this problem)
Mostly it's the format of your OOF email (maybe missing return-path in the header). In which case it's a bit hard (smart host doesn't want to change their filters, and you can't really change OOF procedures in Exchange, as it's hard coded).
Just capture your email traffic to find out exactly why it's being bounced.
