Office 365:Convert shared mailbox to user mailbox with Powershell

by 4 Comments

It’s easy to change the mailbox type in Office 365 with Powershell.

Using the Set-mailbox cmdlet there are four possible types of mailbox that you can set:

  • Regular
  • Room
  • Equipment
  • Shared

Examples to change the type of a mailbox:

PowerShell to change a mailbox type in Office 365

Use the form below to generate the PowerShell Required to change the mailbox type:

  • Fill in the identity value of the mailbox that you want to convert
  • Select the mailbox type that you want to convert it to.
  • Copy and paste the generated code to a PowerShell window.

Remember to set your PowerShell execution policy, otherwise the script will not run. Set the PowerShell execution policy to at least RemoteSigned.

If you are converting to a “Regular” mailbox, ensure that you assign a license after you have run the conversion.

If successful, you should get output like this:

  2. Hi Lucas,

    I get the exact same error since 20/10/2013 !
    I already converted hundreds of mailboxes this way, but apparently Microsoft introduced a bug this weekend on their Exchange Online infrastructure.
