Office 365
Exchange hybrid
PROBLEM:
Office 365 users don’t see on-premise dynamic distribution lists in their Outlook Address Book.
CAUSE:
Due to architectural differences in local Active Directory/Exchange and Office 365, the on-premise Dynamic Distribution Groups do not get replicated to Office 365. This is by design.
SOLUTION:
In Office 365 Exchange online administrative console create mail enabled contact that points to the dynamic distribution list in the on-premise environment.
To create a contact in Exchange Online to represent the dynamic distribution group, follow these steps:
1) Login to Office 365 Exchange Online admin console.
2) Under Recipients/Contacts click on the Plus sign and select Mail Contact
Fill out the details. In the external e-mail address field enter the e-mail address of your on-premise dynamic distribution group. The change will be visible to clients after the next Offline Address Book rebuild (takes place once in 24 hours).
