The Manage installed applications option leads to a screen where you can manage all Exchange content installed in your domain. This screen shows you key information to decide what to do with the content installed in your domain, such as the latest version available or the date it was installed.
You can filter by type or introduce your own filtering criteria in the search box at the top, which will be used to find matches in any of the fields.
Clicking the name of the content opens the content card with all the details.
Click the Uninstall/stop button if you want to remove the content from your domain for all users. An Update button will appear for each item that has a new version available (see Managing content versions for more info).
For alert packs you will see the Manage button instead, which opens the content card for you to manage the included alerts individually or in bulk.
