How To Install Prospect Mail on Linux Mint 22

Linux Mint users who rely on Microsoft Office 365 for email often face challenges finding a native email client that works seamlessly with these services. Prospect Mail offers the perfect solution as an unofficial Outlook client specifically designed for Linux systems. This comprehensive guide will walk you through installing and configuring Prospect Mail on Linux Mint 22, providing you with a familiar Outlook experience without leaving your Linux environment.

What is Prospect Mail?

Prospect Mail is an unofficial Microsoft Outlook client built using Electron technology. It essentially takes the Outlook Web App (OWA) and wraps it into a standalone desktop application, providing a dedicated email experience for Linux users.

As an Electron-based application, Prospect Mail delivers a consistent experience across different Linux distributions, including Linux Mint 22. The application offers core Outlook functionality including:

• Email management with a familiar interface
• Calendar integration for scheduling
• Contact management
• File access and attachment handling

Important limitation: Prospect Mail works exclusively with Microsoft/Office 365 accounts and is not compatible with personal Outlook.com accounts. This makes it particularly valuable for professionals and students who need to access organizational email on Linux systems.

It’s worth noting that Prospect Mail has no direct affiliation with Microsoft – it’s developed and maintained by independent developers who aim to bridge the gap between Microsoft services and Linux operating systems.

Benefits of Using Prospect Mail on Linux Mint 22

Installing Prospect Mail on your Linux Mint 22 system provides several significant advantages:

• Native Office 365 Experience: Get a dedicated application for Outlook rather than keeping browser tabs open. This provides better focus and integration with your desktop environment.
• Desktop Notifications: Receive real-time alerts about new emails and calendar events directly through your Linux Mint notification system.
• Calendar Integration: Access your Office 365 calendar directly within the application, making it easy to manage appointments and meetings.
• Streamlined Workflow: Having a dedicated email application separates your communication from browser activities, potentially improving productivity.
• Familiar Interface: The application closely resembles the web version of Outlook, making it easy for users transitioning from Windows to Linux Mint.

Compared to accessing Outlook via a browser, Prospect Mail generally offers better resource efficiency, improved desktop integration, and a more focused email experience.

Prerequisites for Installation

Before installing Prospect Mail, ensure your Linux Mint 22 system meets these requirements:

System Requirements

• Processor: 1 GHz or faster
• RAM: At least 2 GB (4 GB recommended for optimal performance)
• Disk space: Minimum 500 MB free space
• Active internet connection

Updating Your System

Start by updating your Linux Mint 22 system to ensure all packages are current:

sudo apt update
sudo apt upgrade -y

Depending on your preferred installation method, you may need to install additional package managers. For Snap installation, verify that the Snap package manager is available:

sudo apt install snapd -y

For .deb package installation, ensure you have the necessary utilities:

sudo apt install gdebi-core -y

It’s also helpful to install these potential dependencies:

sudo apt install libappindicator1 libindicator7 -y

Method 1: Installing via Snap Package Manager

The Snap package manager provides one of the simplest methods for installing Prospect Mail on Linux Mint 22.

What is Snap?

Snap is a package management system that allows applications to be packaged with all their dependencies and run in an isolated environment. This ensures consistent operation across different Linux distributions.

Installing Snap Package Manager

Although Linux Mint 22 is based on Ubuntu, it doesn’t come with Snap pre-installed. Open a terminal and run:

sudo apt update
sudo apt install snapd -y

After installation, it’s recommended to log out and log back in or restart your system to ensure all Snap paths are properly updated.

Installing Prospect Mail via Snap

Once Snap is configured, installing Prospect Mail is straightforward:

sudo snap install prospect-mail

The system will download and install Prospect Mail along with all its dependencies.

Verifying Installation

After installation completes, verify that Prospect Mail was installed correctly:

snap list prospect-mail

Launching Prospect Mail

You can launch Prospect Mail in two ways:

1. From the application menu: Navigate to the menu in Linux Mint 22, search for “Prospect Mail,” and click its icon.
2. From the terminal: Simply type:

   prospect-mail

Troubleshooting Snap Installation

If you encounter issues with the Snap installation:

1. Snap path not recognized: Ensure Snap’s bin directory is in your PATH:

   export PATH=$PATH:/snap/bin

2. Permission issues: Use sudo with Snap commands that require elevated privileges.
3. Connection errors: Verify your internet connection and check if Snap services are running:

   sudo systemctl status snapd.service

Method 2: Installing via .deb Package

For users who prefer traditional Debian package installation, the .deb method offers better system integration.

Downloading the .deb Package

First, download the latest Prospect Mail .deb package from the project’s GitHub repository:

wget https://github.com/julian-alarcon/prospect-mail/releases/download/v0.5.4/prospect-mail_0.5.4_amd64.deb

Note: Check for the latest version number on the GitHub releases page.

Installing the Package

Once downloaded, install the package using dpkg:

sudo dpkg -i prospect-mail_0.5.4_amd64.deb

dpkg -l | grep prospect-mail

Launching Prospect Mail

After installation, launch Prospect Mail through:

1. The application menu: Look for Prospect Mail in your applications menu.
2. The terminal: Type:

   prospect-mail

Troubleshooting .deb Installation

Some users have reported issues with spaces in directory names. If Prospect Mail fails to launch, check for path-related errors:

sudo mv "/opt/Prospect Mail" /opt/ProspectMail
sudo ln -sf /opt/ProspectMail/prospect-mail /etc/alternatives/prospect-mail
sudo chmod 4755 /opt/ProspectMail/chrome-sandbox

Method 3: Browser-Based Installation Options

For users preferring a lightweight approach, browser-based installation provides an alternative:

Chrome/Chromium Browser Installation

1. Open Chrome or Chromium browser.
2. Navigate to https://outlook.office.com
3. Log in with your Microsoft/Office 365 account.
4. Click the three dots menu in the top-right corner.
5. Select “More tools” → “Create shortcut…”
6. Check “Open as window” and name it “Prospect Mail”
7. Click “Create”

This creates a desktop shortcut and adds Prospect Mail to your applications menu.

Firefox Browser Installation

2. Navigate to https://outlook.office.com and log in.
3. Click the three-line menu in the top-right corner.

5. Customize the name and click “Add”

Advantages of Browser-Based Installation

• No additional software installation beyond your existing browser
