EFA with O365 Hybrid

Post by SimonBryan »

Hi all
We have a Hybrid O365 setup, MX records point at oulr local Exchange Server and it forwards mail to O365
We have implemented EFA by pointing the firewall rule to EFA and then having it send the mail on to our Exchange Server.
Works brilliantly - however when we need to dot hings like migrate new users to O365 from the local Exchange server EFA blocks O365 online from connecting to the local server. So we have to bypass it, migrate the new users, then enable it again.

Any thoughts on how to get around this?

Cheers
Simon

OK, just ignore this, if we add he user from Exchange and choose O365 Mailbox it all works - the next AD synce creates the suer in O365 and we don't have to migrate anymore.
