NM: Converting a mailbox object to a Room or Resource Object (4329140)

Issue

We provisioned and migrated our rooms and resource objects as user objects in O365, how do we convert these objects back to a room or resource?

Solution

To convert any regular (user) mailbox to a resource mailbox, use the Set-Mailbox cmdlet in PowerShell. You also need to provide the appropriate Type parameter, i.e. Room or Equipment, depending on the type of resource mailbox you want to get.

For example, the cmdlet below converts a regular mailbox to a room mailbox:

Set-Mailbox <mailbox_name> -Type Room

If you want to convert a regular mailbox to an equipment mailbox, use the following cmdlet instead:

Set-Mailbox <mailbox_name> -Type Equipment

Example

Set-ExecutionPolicy RemoteSigned
Set-ExecutionPolicy Unrestricted
$LiveCred = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection
Import-PSSession $Session
Connect-MsolService
Import-Module Msonline

Now issue the following command:

Get-Mailbox -Identity <objectname@mycompany.com> | Set-Mailbox -Type Room

Replace Room with your chosen recipient type to change its function:

Regular
Room
Equipment
Shared

You can find more information regarding these PS commands on the Microsoft web site.
