These instructions are for sending emails directly through Salesforce - not Outlook.

1. In Salesforce, click your avatar/profile picture (top right) → Settings.
   
   
    
2. Left sidebar: Email → Email Settings (or My Email Settings).
   
   
    
3. Find the option that says:“Send emails without leaving Salesforce. Sent emails are logged in Salesforce and appear on the activity timeline.”
   
   
    
4. Change it to Salesforce / Salesforce Email Composer (not “Default Email Application” or “Outlook”).
    
5. Save, then test clicking a contact’s email again.
    

That should bring back the little Salesforce email popup with templates + logging instead of launching Outlook.
