A proxy address is not being "transferred" to the cloud mailbox from on-prem

We have Exchange 2010 and o365 in a hybrid environment.  We setup new mailboxes and migrate them to the cloud. We also migrate old mailboxes to the cloud.  

Currently, we need to add a SMTP address to an on-prem mailbox and for some reason, it is not being shown in the cloud.

If someone has an idea of what to check, please advise.  

Other SMTP addresses of the cloud mailbox are working.

Thanks.
