Dear Coupled Resonators,
Greetings. Thank you for reaching out to Microsoft Community.
Generally, if you are finding Safe Sender's List in Outlook desktop app, do the following:
On the Home tab, click Junk, and then click Junk E-mail Options. You will see safe senders list on the Safe Senders tab.
(You can add your Contacts and other correspondents to the Safe Senders list to confirm you'll always receive their messages in your inbox.)
If above information doesn't meet your needs or you didn't find it, would you mind providing us a little more information to better assist you?
- l learn that you are using Outlook desktop app on a Windows version, but to fully understand your situation, we need to collect certain product information and version number of your Outlook, so, what version of Outlook do you have? Go to File>Office account, you will see product information and version number, kindly provide us a screenshot of that page.
l appreciate your kind cooperation and look forward to hearing from you. Have a good day!
Regards,
Tammy | Microsoft Community Moderator.
