This article describes how to change the password for a Hosted Microsoft Exchange mailbox. Users can change their own password through the User Control Panel, and administrators can change the password for a user through the Cloud Office Control Panel.
- Applies to: User and administrator
- Difficulty: Moderate
- Time needed: Approximately 10 minutes
- Tools required: Users need their current mailbox password; administrators need Cloud Office Control Panel access
For more information about prerequisite terminology, see Cloud Office support terminology.
Note: If you are using an Office 365 Microsoft Exchange mailbox, see the Office 365 documentation for assistance with this task.
Change your password through the User Control Panel
Log in to the User Control Panel with your email address and current password.
Note: If you are unable to log in, try to log in at apps.rackspace.com. If you cannot log in to either site, you must contact your administrator to have your password reset.
Under Change Password, enter your current password, your new password, and your new password again to confirm.
Note: We recommend that you create a password that you have never used before and that remains unique from all your other passwords. Review Password Management and Best Practices for guidance on password creation.
Warning: After you change the password, you must update the password on all devices that connect to this mailbox. If you do not update the password on every device, the mailbox locks itself and you must contact your administrator to unlock it. Give your administrator the “Recover a locked mailbox”" instructions at the end of this article.
Reset a password through the Cloud Office Control Panel
Log in to the Cloud Office Control Panel.
In the Microsoft Exchange section, click Mailboxes.
In the mailbox list, find the mailbox you want to update and click the dropdown arrow by the Manage button.
Within the Change Password pop-up, enter the following information:
- Password: Enter a new password.
- Confirm: Enter the new password again.
Note: We recommend that you create a password that you have never used before and that remains unique from all your other passwords. Also, longer passwords provide better security for your account.
Click Change Password.
Warning: After the password has changed, the user must update the password on all devices that connect to this mailbox. If the password isn’t updated on every device, the mailbox locks itself and users can’t access their email.
Recover a locked mailbox
If a user’s mailbox locks, the administrator and user can follow the steps in this section to unlock it.
(User) Identify every device that connects to the locked mailbox.
(User) Remove the mailbox password from all of the devices, including mobile devices. Do not re-enter the password yet.
(Admin) Log in to the Cloud Office Control Panel and unlock the user’s mailbox.
(User) Log in at apps.rackspace.com. If you cannot log in, the admin must reset your password as outlined in the previous section.
(User) After you have successfully logged into apps.rackspace.com, manually enter your email address and password into each device that connects to the mailbox, one at a time.
