MAPIMAIL File – What is .mapimail file and how to open it?

MAPIMAIL: A Versatile Email Transmission Format

The MAPIMAIL file format is a proprietary email transmission format that enables the exchange of email messages and attachments across various email clients and devices. It was developed by Microsoft and is primarily utilized by the Microsoft Outlook email client. MAPIMAIL files encapsulate email messages, including the email body, attachments, sender and recipient information, and other metadata.

The versatility of MAPIMAIL stems from its cross-platform compatibility. Unlike many email formats tied to specific email clients, MAPIMAIL files can be received and processed by most popular email clients, such as Outlook, Gmail, and Thunderbird. This interoperability enhances email accessibility and allows users to seamlessly transfer messages between different platforms. By leveraging the MAPIMAIL format, email exchanges can occur effortlessly, regardless of the client or device used.

Opening MAPIMAIL Files with Email Clients

MAPIMAIL files are email messages saved in a proprietary format used by Microsoft Outlook and other email clients that support the Messaging Application Programming Interface (MAPI). To open a MAPIMAIL file, you can use the following steps:

1. Locate the MAPIMAIL file: MAPIMAIL files typically have the .MAPIMAIL file extension and are found in the “Temporary Internet Files” folder on your computer.

2. Use an email client that supports MAPI: You can open MAPIMAIL files in email clients that support MAPI, such as Microsoft Outlook, Thunderbird, and Apple Mail. Double-click on the MAPIMAIL file to open it in your default email client.

3. Configure email client settings: If double-clicking on the MAPIMAIL file does not open it, you may need to configure your email client’s settings to associate MAPIMAIL files with the correct program. To do this, go to your email client’s “Preferences” or “Options” settings and navigate to the “File Handling” or “File Associations” section. Find the “.MAPIMAIL” file extension and associate it with the desired email client.

Using Third-Party Software

If you do not have an email client installed that supports MAPI, you can use third-party software to open MAPIMAIL files. Here are two popular options:

1. MAPIMail Viewer: This free software allows you to open and view MAPIMAIL files. It is lightweight and easy to use, making it a convenient option for occasional use.

2. Outlook Express Import Wizard: This free wizard can be used to import MAPIMAIL files into Outlook Express, another email client that supports MAPI. This allows you to view the email messages within Outlook Express and access any attachments that they may contain.

Purpose of MAPIMAIL Files

MAPIMAIL files are associated with the Microsoft Outlook email client and are used to send emails to multiple recipients directly from the desktop. These files contain a collection of recipient information, including email addresses, names, and other contact details. MAPIMAIL files simplify the process of sending emails by allowing users to create and save a list of recipients for future use. They are particularly useful for scenarios where emails need to be sent to the same group of people on a regular basis.

Structure of MAPIMAIL Files

MAPIMAIL files are structured using a XML (Extensible Markup Language) format. They consist of a series of nested elements that define the recipient information. The structure includes elements that represent the sender’s email address, the email subject, and a list of recipient email addresses. Additionally, MAPIMAIL files can contain optional elements for specifying additional information such as the email body and attachments. When a MAPIMAIL file is opened, Outlook automatically parses the XML structure and creates an email message with the specified recipient information.
