Managing Members

Inviting Team Members

If enabled by your System Admin, you can add people to your team in one of three ways: You can send a direct invite; you can share a public team invite link; or if they already have an account on the server, you can add them to the team yourself.

Direct Invites

Direct invites are invitation emails sent from your team’s server directly to the invited person’s email address. A link within the invitation directs them to an account creation page. Invitation links sent by email expire after 48 hours and can be used only one time. A System Admin can invalidate all active invitation links via System Console > Security > Sign Up > Invalidate pending email invites in prior versions or System Console > Authentication > Signup > Invalidate pending email invites in versions after 5.12.

To send a direct invite:

  1. Click your username, at the top of the Navigation Panel.
  2. Click Send Email Invite and enter the person’s email address along with their first and last name.
  3. To invite more than one person, click Add another.
  4. Click Send Invitation.


If you do not see the Send Email Invite option, confirm with your System Admin that System Console > Security > Sign Up > Enable Email Invitations is set to true in prior versions or System Console > Authentication > Signup > Enable Email Invitations in versions after 5.12.

Adding Someone to Your Team

If someone you want to add to your team already has an account on the server, you can add them to your team without sending an invitation.

To add someone to your team:

  1. Click your username, at the top of the Navigation Panel.
  2. Click Add Members to Team. The Add New Members window opens.
  3. Click the username of the person or people to add to your team. You can type in the search box to filter the list. If the people you want to add are not on the list, then they are either already on your team or they do not have an account on your server.

User Roles

There are five types of user roles with different permission levels in Mattermost: System Admins, Team Admins, Channel Admins, Members, and Inactive accounts. To view a list of users on the team and what their roles are, Team Administrators can go to the three dot Main Menu and select Manage Members.


This is the default role given to users when they join a team. Members have basic permissions on the Mattermost team.

Channel Admin

Available in Enterprise Edition E10 and higher

The person who creates a channel is assigned the Channel Admin role for that channel. People with the Channel Admin role have the following privileges:

  • Ability to assign the Channel Admin role to other members of the channel.
  • Ability to remove the Channel Admin role from other holders of the Channel Admin role.
  • Ability to remove members from the channel.

Depending on your system configuration, Channel Admins can be granted special permissions by the System Admin to rename and delete channels.

Team Admin

When a team is first created, the person who set it up is made a Team Administrator. It is a team specific role, meaning that someone can be a Team Admin for one team but only a Member on another team. Team Administrators have the following privileges:

  • Access to the “Team Settings” menu from the team site main menu
  • Ability to change the team name and import data from Slack export files
  • Access to the “Manage Members” menu, where they can control whether team members are “Members” or “Team Administrators”

System Admin

The first user added to a newly installed Mattermost system is assigned the System Admin role.

The System Admin is typically a member of the IT staff and has all the privileges of a Team Admin, along with the following additional privileges:

  • Access to the System Console from the main menu in any team site
  • Ability to change any setting on the Mattermost server available in the System Console
  • Ability to promote and demote other users to and from the System Admin role
  • Ability to deactivate user accounts and to reactivate them
  • Access to private channels, but only if given the link to the private channel

A System Admin can view and manage users in System Console > Users. They can search users by name, filter users by teams and filter to view other System Admins as well as inactive users.

User With Personal Access Token Permission

A System Admin can enable personal access tokens and give permissions for that account to create personal access tokens in System Console > Users.

In addition, the System Admin can optionally set the following permissions for the account, useful for integrations and bot accounts:

  • post:all: Allows the account to post to all Mattermost channels including direct messages.
  • post:channels: Allows the account to post to all Mattermost public channels.

Deactivating Users

A System Admin can deactivate user accounts by going to System Console > Users for a list of all users on the server. The list can be searched and filtered to make finding users easier. Click the user’s role and in the menu that opens, click Deactivate.

When Deactivate is selected, the user is logged out of the system, and receives an error message if they try to log back in. The user no longer appears in channel member lists, and they are removed from the team members list. A deactivated account can also be reactivated from the System Console, in which case the user rejoins channels and teams that they previously belonged to.

Direct Message channels with deactivated users are hidden in users’ sidebars, but can be reopened using the More… button or the Channel Switcher (CMD/CTRL + K).

Mattermost is designed as a system-of-record, so there is not an option to delete users from the Mattermost system, as such an operation could compromise the integrity of message archives.

Note that AD/LDAP user accounts cannot be deactivated from Mattermost; they must be deactivated from your Active Directory.

Removing a User from a Team or Leaving a Team

Remove from Team

Any Team Administrator has the ability to remove a user from a team by going to the three dot Main Menu > Manage Members, and selecting Remove From Team in the dropdown menu beside a user entry.

When a user is removed from a team, the team will no longer show up in their team sidebar. If they currently have the team open, they are redirected to the first team that appears on their team sidebar. If they didn’t belong to any other teams, the user is sent to the team selection page.

Removing a user from the team does not deactivate the account. The user will still be able to sign in to the site, and join other teams. They will also be able to rejoin the team they were removed from if they receive another invite, or if the team is set to “Allow any user with an account on this server to join this team”. If the user does rejoin the team, they will no longer belong to the channels they were previously a part of, and they will lose all Admin privileges if they had them previously.

A System Administrator can also remove users from teams by going to System Console > Users, and selecting the dropdown beside a user entry and clicking Manage Teams.

Leaving a Team

Users can also choose to remove themselves from a team, by going to the three dot Main Menu > Leave Team. This will remove the user from the team, and from all public channels and private channels on the team.

They will only be able to rejoin the team if it is set to “Allow any user with an account on this server to join this team” team, or if they receive a new invite. If they do rejoin, they will no longer be a part of their old channels.
