Add-ins or Plugins for Outlook lets you add additional features and integrations with other apps. Add-ins are available for a number of apps like Doodle, Salesforce, Zoom, and more.
Install Add-ins from Outlook Desktop
In Outlook, navigate to File > Info and select Manage Add-ins
You will be taken to Outlook Online. If you're not currently signed in to your Adler account, you will be prompted to do so. If you're currently signed in to another Outlook account, please sign out or use a different browser profile. Outlook Online will show you a list of Add-Ins for Outlook.
Search for the Add-in you want and select it. In this example, I'm adding the Salesforce Add-in.
Select Install or Add on the Add-in's page. Once you've installed it this page will say Added in the place of Install.
Outlook will notify you that the Add-In has been installed. Depending on the Add-in you install, the toolbar will have new items available related to the Add-in's features.
