Mattermost Desktop
Mattermost Desktop 6.2.2 is a Windows, macOS and Linux client for Mattermost servers, with multiple server profiles, notifications, files and team collaboration.
What Mattermost Desktop does
Mattermost Desktop connects to one or more Mattermost servers and provides team channels, messages, notifications and file operations. The server controls accounts, teams, permissions, retention and stored content; the desktop application is not a standalone chat server.
Platform and architecture boundaries
Version 6.2.2 includes Windows x64 and ARM64, macOS Intel and Apple silicon, and Linux x64 and ARM64 packages. Choose the package that matches the processor and operating system instead of relying on a compatibility layer.
Server and account boundaries
Confirm the organization-provided server address, certificate, login method, proxy and client-server compatibility before signing in. Separate personal and work accounts, and treat local caches and server profiles as sensitive on shared computers.
Upgrade and file retention
A desktop upgrade does not replace a server upgrade. Messages and files remain subject to server storage, permissions, retention and size policies. Keep important files in the organization-approved archive rather than relying on a local cache.

Mattermost Desktop 6.2.2 installation and server connection guide
Confirm the organization server and login method, install the matching architecture, verify a test team and file, then document notification, logout and upgrade behavior.
Before you start
- Select Windows x64 or ARM64, macOS Intel or Apple silicon, or Linux x64 or ARM64 as appropriate.
- Prepare the server address, account method, proxy and certificate requirements from the organization administrator.
- Use a test channel and a small non-sensitive file to verify messages, notifications, upload, download and logout.
Installation steps
- 01
Install the matching package
Use MSI or ZIP on Windows, the matching DMG on macOS, or TAR, DEB, RPM, AppImage or Flatpak on Linux.
- 02
Add the server profile
Enter the organization-provided address, verify the domain, certificate and login page and then complete account authentication.
- 03
Verify a team and file
Enter a test team and channel, send a message, upload a small file and check notifications, permissions, download behavior and a second login.
Quick start
- 01
Separate multiple organizations
Give each server a clear name and notification policy, keep work and personal accounts separate and review the saved server list regularly.
- 02
Configure notification and cache behavior
Tune channel and time-based notifications, then log out on a shared computer and clear local cache according to the organization policy.
- 03
Record an upgrade rollback
Note the desktop version, server version and custom launch options before upgrading. If sign-in or notification behavior changes, reproduce it in a test profile first.
Usage tips
- A desktop upgrade does not replace a server upgrade. Connection problems can come from server version, certificates, proxy rules or organization policy.
- File and message behavior depends on server storage, permissions, retention and size limits. Archive important material according to the organization process.
- Custom packages and preconfigured server addresses must follow the client license, branding and distribution rules.
Troubleshooting and uninstall
Why can I not sign in after entering the server address?
Check protocol, domain, certificate and the organization login method, then compare browser access and the desktop log to separate a server issue from a local network issue.
Why do messages work but file upload fails?
Check channel permission, file size, server storage and proxy limits with a small test file, then contact the server administrator instead of repeatedly uploading a large file.
- Sign out of every organizationExit each server profile, record addresses and approved account recovery details and archive important files according to the organization process.
- Uninstall and clear cacheRemove Mattermost Desktop through system application management and clear local cache and logs only after checking audit and retention requirements.
Frequently asked questions
Does Mattermost Desktop include a chat server?
No. It connects to a Mattermost server, while accounts, teams, messages, files and permissions are controlled by that server.
Can I connect multiple servers at once?
The client supports multiple server profiles, but keep organization accounts, notifications and cache policies separate, especially on a shared computer.
Which Windows package should I use?
Match x64 or ARM64 to the processor, and also match Intel or Apple silicon on macOS. A mismatched package can fail to install or run through a compatibility layer.
