SEFAUTIL service in a hybrid solution

SEFAUtil (secondary extension feature activation)

I installed Sefautil server and I hade problem to run the powershell commands set-csuserforwarding -sipaddress……
My server has two domain1.com and domain2.com.
The second fact is that the solution is running in an hybrid solution with some users in Office 365 and other user on the local server.
With a hybrid solution you need to point your sip.domain.com to the ip-address on your edge server.
If this isn’t done, your “onprem” users cannot have full dialog between onprem and online users.
My solution two get both domain1.com and domain2.com working great with sefautil server was to add sip.domain1.com and sip.domain2.com to my local frontend server host table with the IP-address to the local FE-server

Without this quickfix I got the error when I ran the command
Set-CsUserForwarding : The server was unable to process the request due to an internal error.  For more information…

After the host table was updated sip.domain1.com and sip.domain2.com pointing to local FE-server,
I just restarted sefautil service and Voila it worked like a dream.
