I have been getting the following error since i have added my new domain to office 365.
I am trying to use a current user with the new domain which was added with no issues.
the error i get - "You can't use the domain because it's not an accepted domain for Exchange System yet. If the domain is newly added, it usually take a few hours for the domain information to propagate. Please wait at least 4 hours to try it again."
its been more then 24 hours after i have added it and still the same error.
