You can block or remove a user from the business account:
When you block a user, the user's access to the account is revoked, but the user remains a member of the account and can be unblocked. You can use this functionality to temporarily block users when you need to perform maintenance of the account or some other similar task.
When you remove a user, they are completely removed from the business account. You can later invite the user to join the business account again if you wish.
To block or remove a user from the business account:
Make sure your business account is selected on the Dashboard and click Business Profile in the upper right.
Click Users in the upper right.
Click on a user name.
In the dialog that opens, click Block or Remove.
Click Save.
The user will receive an email with a message that their business account membership has been blocked or canceled. If you wish to unblock a user, repeat the steps above and click Unblock.
