Hi,
We have exchange 2010 server setup with office 365 in hybrid mode. We moved some users mailboxes from exchange server to office365. Now we have some DL on exchange server that have some users (mailboxes on prem.) and some users (mailboxes on office365). When we send the mail to that DL, we received error "Your message can't be delivered because delivery to this address is restricted."
How can we resolve this issue? Please help me.
Thanks & Regards,
