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 -Identity admin | fl *name*,Id*
SamAccountName : admin56315-149665953
UserPrincipalName : firstname.lastname@domain.com
DisplayName : Firstname Lastname
SimpleDisplayName :
Name : admin
DistinguishedName : CN=admin,OU=domain.onmicrosoft.com,OU=Microsoft Exchange Hosted Organizations,DC=redacted,DC=PROD,DC=OUTLOOK,DC=COM
Identity : admin
Id : admin
See further below what all the other mailboxes look like.
Problem is that when I select that mailbox, i.e. in Exchange Admin Center to be added to a group or similar, I see not the DisplayName, but "admin".
Thanks
Dan

SolutionSimply 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 @Vasil Michev
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!
