If you're using the Outlook desktop add-in, you can configure your default options for the add-in, including switching your connected account, setting your default log and track settings, and managing your Never log settings.
To access your settings:
If you want the contact profiles sidebar to appear in your email account when sending emails to your contacts, select the Show Contact Profiles checkbox.
You can customize your default log and track preferences so the settings are applied each time you send an email.
Emails sent to an email address or domain included in your Never log list will never save to your CRM. Email tracking activity will also not appear on the contact's timeline.
When you're finished configuring your desktop add-in, click Save at the bottom.
