Dkim with multiple domains in Office 365
Hi, I´m about to implement DKIM and DMARC in to an orginzation with multiple domains (7). Every user uses the same domain name but it´s some shared mailboxes which can have different domain name...
Hi Martin,
No worries, glad I could help. If you did want to run a quick check you can run:
Get-Mailbox |Select DisplayName, GrantSendOnBehalfTo
It should give you an output like in the attached picture.
Take care,
Yes I remember the issue - SendAs works but SendonBehalfOf failed as the DKIM generation was incorrectly set. I believe this was raised to Microsoft and resolved - but I haven't seen any further information on it since. Do you have SendonBehalfOf utilised a lot in your Org?
As i know, they are not working with sendasbehalf, so it shouldn´t be any issue then!
Thanks for the clarification!
