You have an on-premises Exchange organization. The organization plans to migrate to Exchange Online.
Users report that after their mailboxes are migrated to Exchange Online they are no longer able to send email to a specific dynamic distribution list. All other distribution lists work as expected.
You need to resolve the issue.
What should you do?
- A. In the Active Directory Synchronization Services console, change the connector filter to include dynamic distribution lists.
- B. In Office 365, re-create the dynamic distribution list.
- C. Run the following Windows PowerShell cmdlet: Set-DynamicDistributionGroup
- D. Reduce the number of members in the distribution list to fewer than 1,500 contacts.
