Restoremailbox positional parameters

Edit online

Positional parameters immediately follow the restoremailbox command and precede the optional parameters.

original-mailboxname
Use this parameter to specify the name of the mailbox to restore from. The mailbox name can be either the mailbox-alias, the mailbox-display name, or the mailbox globally unique identifier (GUID). The original-mailboxname parameter is required.

To specify more than one name, separate them by commas.

If any mailbox name contains blanks, enclose the entire mailbox name in double quotation marks.
