Converting a shared mailbox to user mailbox [ Exchange 2013 & Office365 ]

Recently I was working on a migration from on-premises Exchange 2010 servers to Office365 . As Office365 is based on Exchange 2013 I decided to created the multi-accessed mailboxes as a shared mailboxes rather than user mailboxes.

After a while a request was raised requesting changing one of the shared mailboxes to a user mailbox ( as it will be used for an authenticated application )

The conversion is doable using PowerShell , as follow :

  • Connect to Office365 using remote PowerShell using the following steps
    • Store your Office365 credentials , as follow


    • At the credentials popup enter your credentials and hit Enter
    • Create a remote session using the following PowerShell cmdlet

$Office365Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $Office365Cred -Authentication Basic –AllowRedirection

    • Then import the remote PowerShell session

Import-PSSession $Office365Session


  • Once the session is completely imported you can do conversion as follow :
    • First , make sure that the mailbox is a shared mailbox using the following PowerShell cmdlet

Get-Mailbox –Identity “Shared Mailbox Display Name” | fl Name,RecipientType,RecipientTypeDetails


    • Perform the conversion using Set-Mailbox cmdlet , then verify as above :

Set-Mailbox –Identity “Shared Mailbox Display Name”  -Type:Regular


Now you have successfully did the conversion Winking smile
