How to change the Recipient Type of a Mailbox in Exchange or Office 365

/

If you need to change the purpose of an existing Exchange Mailbox, for instance changing a User Mailbox to a Shared Mailbox or maybe the other way around, changing a Shared Mailbox to a User Mailbox.

Could also be changing to a Room or Equipment.

This an relative easy task to change. Make sure your running the Exchange Management Shell or are connected Office 365 (see previous post).

Change a mailbox to a Shared Mailbox, using the following PowerShell command:

Get-Mailbox -Identity [email protected] | Set-Mailbox -Type Shared

The different Recipient Types you can set on a Mailbox are:

  • Regular
  • Room
  • Equipment
  • Shared

Show a list of mailbox and their Recipient Type, using the following PowerShell command to validate your configuration settings:

Get-Mailbox | ft Name, RecipientTypeDetails

Output (example):

The above commands works fine on Exchange 2007, Exchange 2010 and with Office 365.

  1. Hi,

    I want to set a transport rule in my Exchange 2013 where every e-mail comes to a recipient will be CC to the recipient’s manager.

    How to do that?

    Thanks a lot for the answer.

    Regards,

    Harwianto

  2. Thanks! I couldn’t figure out the field names (I was using field names with spaces which didn’t work).

  4. Hi Can we change mailbox type from Linked mail box to remote mailbox?
    Object Type RecipientTypeDetails (Decimal Value)

    Linked Mailbox 2

    Remote User Mailbox                                                                   2147483648         

    • It is not as simple as just changing type. You would have to move the exiting mailbox to a Remote User Mailbox, which it often referred to as the Office 365 Mailbox of a user. Hope that answers your question.
