- Device & OS
- not provided
- Scenario
- Managing contacts and groups in a hybrid Exchange and Azure AD synchronization environment.
- Observed behavior
- The Distribution groups option is missing for specific users, while new users in the same environment can see it without issue.
Verify that you have administrative access to the Microsoft 365 admin center and confirm the role assignment policies are correctly configured for the affected users.
Investigate Hybrid Exchange and Azure AD Attributes
Compare Exchange attributes and synchronization status between affected and unaffected users in your hybrid environment to isolate the cause.
In a hybrid Exchange environment, discrepancies in user interfaces like Outlook on the web often stem from synchronization issues between on-premises Active Directory and Azure AD. Identifying differences in backend attributes is the key to resolving missing options.
Ensure that the affected user's mailbox type perfectly matches that of a user who can currently see the distribution groups option.
Double-check the role assignment policies in the Exchange Admin Center to ensure no custom or conflicting policies are hiding the distribution groups.
Review the Azure AD synchronization logs to verify that all user attributes are syncing correctly between your on-premises Exchange server and Microsoft 365.
If the discrepancy cannot be found locally, post your findings in the Microsoft Q&A hybrid Exchange forum to ask for specialized assistance from hybrid environment experts.
