[A] To pause account access of a particular user, you can remove all permissions for that user.
[B] In TranZact if a user belongs to a team, their permissions cannot be changed independent of the team.
[C] In this case we can create a new team with that user as the only member. By removing the permissions of this newly created team, you can remove permissions for that user.
[D] In order to do that go to the Settings module and select the Users tab. Click on Add Team.
[E] Fill in the team name and description and click Save Details.
[F] After the new team is created, go to the user whose account is to be paused. Click on the edit icon next to their name.
[G] In the Team field, change their team to the one that you just created.
[H] Under the Teams tab, go to the recently created team.
[I] Go to Permissions(1) and deselect all the permissions. But as you can see, by default all the permissions are deselected. Click on Save(2). Now the account of the user is paused.
