Change a user's email address (0:22)

Renaming a mailbox gives a user a new email address and login, without deleting their mail. Use it for a name change, a spelling fix, or when a role address like info@ should become sales@. It is different from editing a mailbox, which only changes the display name or the size limit.

Rename the mailbox

You need a domain admin account other than the one you are renaming.

1. Log in to webmail as a domain admin, then click Domain Settings, then Accounts.

2. Click the user you want to rename to open their page. Rename is not in the … menu on the list itself.

   

3. On the user’s page, click the … button, then choose Rename. You cannot rename the account you are logged in with. To rename the admin account, log in with another admin account.

4. The Change Username dialog shows the Old Username. In New Username, type only the part before the @, for example sales (not sales@yourcompany.com). Click Save.

   

After the rename

Do these straight away, because the old address stops working the moment you save.

• The old address stops receiving mail immediately. Right away, create an alias with the old name pointing to the renamed mailbox, so messages still sent to it are not lost.
• Every phone and computer app signed in to this mailbox must sign in again with the new address as the username. Server settings stay the same: mail.officeniaga.com, port 993 (IMAP), 995 (POP3) or 465 (SMTP).
• Colleagues in your company will see the new address in the Global Address List once it is saved. Tell customers and suppliers yourself, because they cannot see it there.

Use Impersonate User to check the renamed mailbox works before telling the user.

Common issues

What happens to mail sent to the old address after a rename?

It stops arriving right away. Create an alias for the old address that points to the renamed mailbox, so nothing bounces. See Create an alias or mailing list.

Do phone and computer email apps keep working after a rename?

No. Every app must sign in again using the new address as the username. See Move your email to a new phone or computer.

Is this the same as changing a display name?

No. Renaming changes the email address and login itself. Changing only the display name or mailbox size uses a different screen. See Change display name and mailbox quota.
