Hello Everyone,
I have used the Anit-spam auto-forwarding policy to disable the auto-forwarding which is working as expected but the only problem is if anyone whose forwarding is not enabled sending email to the person whose forwarding is enabled getting NDR don't know why.
Why the sender is getting informed about the recipient auto-forwarding is disabled. The emails are getting delivered to the recipient (whose forwarding is enabled) but getting NDR at the same time why?????????????
It means when any internal or external user sending email to the person whose auto-forwarding is enabled getting NDR. (Confused)
Tried under my test tenant but it's the same behavior which actually Microsoft needs to look into.
Why is the SENDER is informed that the RECEIPIENT is not allowed to forward their e-mails?
