Hi Team, We are in a Hybrid Environment ( Office 365 ), we have a user validation issue for a specific user, for a user, user name and display name in Local AD is "FirstName LastName" , however upon checking GAL it shows as "Firstname.Lastname". User displayname in MSO is "FirstName LastName, However in EXO it is "FirstName.LastName" , How do i ensure that the displayname between EXO AND MSO matches? Please suggest how do i go about addressing this problem. Thanks.

    @MasterBlaster

    I would suggest you try to change one of attributes(Such as set a new display name for this account) for this AD account, then check from Office 365, whether the modify sync to AAD account. After modifing, you can use command below to manually force sync: 

    Start-ADSyncSyncCycle -PolicyType Delta

    If AAD account doesn't changed with the local AD account, it means there exist issue with the AAD Connect, you may need to check from the AAD Connect side. You can try to use hared match to match the local AD account with the AAD account

    Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

    If this change could sync to AAD account, I would suggest you check from details panel, sometimes, there exist a delay:

    Wait for a while, it show correctly:

    If it still not show correctly, you could create a service request to Office 365 to let them help you check from the backend: Ways to contact support for business products - Admin Help
