Notes:

• Users can manually remove entries from the safe senders list within their Outlook. If a user deletes a domain from the Safe Senders list and restarts outlook the item will reappear in the Safe Senders list if the policy remains in affect.

• If a user adds a new entry to the Safe Senders list in Outlook, the item will be removed if you are deploying the items for that tab by using Group Policy and if you also enable the Overwrite or Append Junk Mail Import policy.

• By enabling this policy, you force Outlook to overwrite items in the list with the items specified in the list for the corresponding policy.
