How to change a Mailbox Id,Identity, Name ?

For whatever reason, one mailbox in an Office 365 tenant has the name/Id/Identity/CN set as "admin". I would like to change that to be like the other mailboxes. How can I do this?    Get-Mailbox -I...

    Simply use the Set-User cmdlet, Set-Mailbox should also do. Or if you are synchronizing from on-premises AD, make the changes there.

    Thanks a lot VasilMichev 

     

    Set-User -Identity firstname.lastname@domain.com -name firstname.lastname

     

    did it! All the fields are now set correctly:

    Name :               firstname.lastname
DistinguishedName :  CN=firstname.lastname,OU=redacted.onmicrosoft.com,OU=Microsoft Exchange Hosted Organizations,DC=redacted,DC=PROD,DC=OUTLOOK,DC=COM
Identity :           firstname.lastname
Id :                 firstname.lastname

     

    Many thanks!
