Mail and Calendar, formerly known as Windows Mail, is an email client developed by Microsoft for its Windows operating system. It should not be confused with Outlook, another popular email application developed by Microsoft. Microsoft Mail and Calendar allows users to manage multiple email accounts from a single app, making it easier to monitor and organize their emails.

Microsoft's Mail and Calendar app are multi-functional tools that assist users in keeping up with their email correspondence, scheduling events and appointments, and staying connected with friends and family. These app are tailored for both professional and personal use, allowing for efficient communication across all email accounts. They are compatible with several accounts, including Office 365, Exchange,, Gmail, Yahoo!, and other commonly used email services.

Mail was first released in 2005 for the Windows Vista operating system, and it was a groundbreaking app at the time. It introduced advanced features such as improved security, junk email filtering, and email attachment blocking, among other notable functionalities.

Since then, Microsoft has continued to support Mail, making it available on all subsequent versions of Windows up to the latest Windows 11 operating system. Windows users should be familiar with Mail as it comes preloaded on their devices.

Main Features
The rationale behind using an email client is to manage multiple email addresses from a single app. Instead of downloading different apps or opening separate tabs on a web browser, the user can add multiple accounts to Microsoft Mail and Calendar and monitor all their emails from it.

After launching the app, the first step is to add an email account. The app supports emails from Outlook, Google, Yahoo, iCloud, an in-house Microsoft Exchange server, or any other email service using the Internet Message Access Protocol (IMAP) or Post Office Protocol (POP).

The user can choose whichever email provider they use, and the app will redirect them to an in-built browser pane where they’ll log in and permit it to access their emails. The login process works smoothly if the user has valid credentials. Afterward, the user can wait for the emails to sync and begin using the app.

The user can check their Inbox to see any unread mail they have. After reading, they can reply from the app or forward the email to other email addresses. The user can also Archive emails to store them somewhere outside their inbox and retrieve them later.

Microsoft’s Mail app uses Bayesian spam filtering to protect users from suspicious emails. This technique works by correlating the use of specific words with spam and non-spam emails and then applying a mathematical formula to calculate the probability of an email being spam or not.

Any new email flagged as spam gets sent automatically to a Spam folder, where it’ll wait for permanent deletion after 30 days. This waiting period is because the spam filters aren’t perfect and may flag a valid email as suspicious. Hence, the user can always go to the Spam folder if they expect an email but can’t see it in their inbox. It could be that the app’s filters sent it to the spam folder. If so, the user can restore it to the original inbox.

To compose a new email, the user can look for the New mail button and click on it. It’ll open the composition panel, where they can type the text they want to send. The user can send mail to a single address or multiple addresses simultaneously.

The user can attach documents like photos, videos, and PDF documents to their emails. However, this app has a maximum file attachment size limit of 25MB. To circumvent this limit, the user can upload the file to an external cloud storage service (e.g., Dropbox or OneDrive) and link to it on the message panel.

This app lets the user insert tables, pictures, or emojis into emails. Likewise, the user can add a virtual drawing canvas and use their mouse as the drawing pencil to create diagrams. This feature is a unique one that they’ll hardly find in a typical email client.

To ensure the user doesn’t miss important emails, it lets them enable notifications for each account. If they do that, they’ll get an automatic alert anytime a new email arrives in their inbox even if the Mail & Calendar app isn’t currently open. They may include a notification sound to get their attention when they’re not operating their PC.

MS Mail and Calendar lets the user assign signatures for each of their email accounts. These signatures are text that’ll appear at the end of every email they send, similar to signing a letter. They make the sender look professional and thus are common in corporate settings.

The user can create automated replies for every email that arrives in their inbox. This feature is often used to tell people that they won't be responding right away to their emails and to inform them if they’re on vacation or personal leave. It’s beneficial in workplace settings so the user doesn’t leave people waiting for a response without knowing they’re not on duty.

User Interface

The user interface of this desktop app is considered one of the best for an email client. It has a minimal and uncluttered design, which makes it effortless for any user to navigate. Users can easily experiment with the app's settings and features.


Using the Mail & Calendar app is completely FREE of charge. You can simply download it from the Microsoft Store or FileHorse and take advantage of all its features without any cost.
