An Exchange administrator wanted to know the best way to add addresses to the Safe sender
list for his users.
What is the best way to add to the safe sender list for a single user? We
already have some rules for domains we work with, but I really don't want to be creating rules for users.
The user can add addresses to the safe senders list by right clicking on a message list and choosing Junk, Never Block Sender or choose one of the Block options to add to the blocked lists.
If you need to add the address to the Safe Senders (or Blocked Senders) lists for all users or a group of users, you can use Group Policy to append entries to or replace the list on user’s computers. Create a text file containing a list of the e-mail addresses to append to or overwrite the list then add the path to the Group Policy Editor under Microsoft Outlook, Outlook Options, Preferences, Junk Email. (You'll need the Office group policy templates installed and in use, of course.)
If you are having problems with Exchange rejecting the messages, you’ll need to create a whitelist on the server and configure the rule to bypass spam checks.
- In Exchange Online, open the Exchange Admin Center
- Select Protection then select Spam filter
- Select the Default rule (or the desired rule, if using more than one) and click the pencil icon or double click to open the dialog
- Click the plus sign to add email addresses or domains to the Allow lists or Block Lists
