Creation of new Exchange mailbox in CCP fails with the error:

E-mail address 'mailbox@domain.tld' is already registered for some mailbox (ID=1,234). E-mail address should be unique.


Such e-mail address has already been added to some mailbox as additional e-mail address.


If you need to create a separate mailbox with such address, it will be necessary to remove it from the list of additional e-mail addresses first.

It can be done in the following way:

  1. Find the e-mail address using the ID specified in the error message: in Customer Control Panel open the list of mailboxes for the subscription, filter them by ID (specify it without a comma)
  2. Click on Display Name of found mailbox and switch to Additional E-mail Addresses tab
  3. Remove the problem e-mail address from the displayed list.
  4. Try to create mailbox again.
