1. From your desktop, click your workspace name in the top left.
   
2. Select Settings &administration from the menu, then click on Manage members.
3. Click on the  three dots icon next to the account that you want to reactivate.
4. Click on Activate account.

Reactivated members can immediately sign in to the workspace. They'll also have access to any messages that they sent prior to their account being deactivated, but they won't be added back to channels that they were previously in.

Members that have been deactivated at the org level must be reactivated by an org owner or admin before they can rejoin a workspace. Members with active accounts within an org can be reinstated to a workspace by a workspace owner or admin.

Org level

Org owners and admins can reactivate any members who have been deactivated at the org level:

1. From your desktop, click on your workspace name in the top left.
   
2. Select Settings & administration, then click Organisation settings.
3. Click on  People in the left sidebar, then select Members. 
4. Select View deactivated members in the top right.
5. Tick the box next to any members that you’d like to reactivate.
6. Click Single-channel guest, Multi-channel guest or Member to select a role for and reactivate the selected members.

Reactivated members can discover and join workspaces in the organisation. Org owners can also add reactivated members to workspaces manually or through an identity provider.

Workspace level

Workspace owners and admins can reinstate members who have been removed from their workspace, as long as their member accounts are still active within the org. Here’s how:

1. From your desktop, click your workspace name in the top left.
   
2. Select Settings & administration from the menu, then click on Manage members.
3. Next to the search bar on the right, click on Filters, then choose Members removed from the workspace.
4. Click the  three dots icon next to the member that you'd like to reinstate.
5. Click on Add to workspace.

Reinstated members can immediately sign in to the workspace. They can also access messages that they sent before their account was removed from the workspace but won't be automatically added back to channels that they were previously in.
