Exempt An Account

Whether it is a user or a functional account these may need to be exempted. 

If you are getting repeated notifications on the same user you can exempt them. Before exempting the account you should check if the User’s email address is listed in multiple locations and switch between primary and alias addresses.

New: User Mass Update – Exempt from Sync

We have improved the experience for managing user sync exemptions by allowing admins to directly add users to the sync exemption list directly from the User Management– Users page. Select the user accounts you wish to update. Then check the boxes to the left of the names(s) and then clicking the Mass Update button.

Then Click Update Users button. If you go and check in your Azure summary you will now find the account(s) in the exempted area.

2. Temporarily change the Sync Frequency to Never. (This stops unwanted syncing during these steps.) 

3. Click on Search now (AD) or Save and Run Sync Now (Azure).

4. In the AD or Azure Sync summary, Find the account(s) in the adding area. (This screen is also the same in both AD and Azure)

If the accounts are listed in that area, you can click on the check box to the left of the name(s) and then over to the right side click Exempt from Sync if just one account and Exempt Selected on multiple accounts.

5. If the account(s) are marked as a User account instead of a Functional account- then follow this article to convert it to a Functional Account Adding Functional Accounts Manually

6. Once that is done, you will find the accounts in the account in the deleting area. This is because AD or Azure AD is still seeing this as a user account. Expand the Deleting area and mark the box(es) with a check and either select on Exempt From Sync or Exempt Selected for multiple accounts. 

7. Remember to change the Sync Frequency back to desired interval. 

8. Save your changes. 

Once you mark an account Exempt it will no longer sync on a scheduled AD or Azure sync. It will remain in the state until you delete the account or change the status back to Add to Sync. That will then look to the AD system and follow whatever it says there.
