Outlook is available on multiple platforms already including the web, iOS, and Android. But today, without much fanfare, Microsoft seems to have made its new Outlook extension for Edge available for the public, albeit with a "preview" tag. The name of the extension is "Microsoft Outlook" but the "preview" iconography can be seen its store listing.

The extension, which can be downloaded from the Microsoft Edge Add-ons store here, essentially allows you to use Outlook directly in any tab of the browser without opening a new window. After you download it, an icon for Outlook will be visible on the address bar, and when you sign in, you'll be able to get a view of your emails, calendar, contacts, and tasks, among other things. The features mentioned in the store listing are as follows:

• Access work or personal accounts
• Read, send, and manage email and get new email notifications
• Create events, view upcoming ones, and join online meetings
• Create, track, and manage tasks
• Manage contacts

It is important to note that the extension can only be downloaded on Microsoft Edge and is not compatible with other browsers like Google Chrome.

The store listing indicates that the extension was last updated on June 14, 2021, so it's currently unclear whether it has just been made available to the public or if it's only been discovered now. Given the lack of an official announcement from Microsoft as well as the fact that it doesn't pop up in search results, any possibility is equally likely. Although some users have reported they have already started seeing ads for the extension in their Outlook clients. We'll let you know when Microsoft officially announces the extension but in the meantime, you can take it for a spin on Edge here.
