Convert a Mailbox
Applies to: Exchange Online, Exchange Server 2013
Topic Last Modified: 2017-04-26
Converting a mailbox to a different type of mailbox is very similar to the experience in Exchange 2010. You must still use the Set-Mailbox cmdlet in the Shell to do the conversion.
You can convert the following mailboxes from one type to another:
User mailbox to resource (room or equipment) mailbox
Shared mailbox to user mailbox
Shared mailbox to resource mailbox
Resource mailbox to user mailbox
Resource mailbox to shared mailbox
Note: If your organization uses a hybrid Exchange environment, you need to manage your mailboxes by using the on-premises Exchange management tools. To convert a mailbox in a hybrid environment, you might need to move the mailbox back to on-premises Exchange, convert the mailbox type, and then move it back to Office 365.
Estimated time to complete: 5 minutes.
You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Recipient Provisioning Permissions" section in the Recipients Permissions topic.
This example converts the shared mailbox, MarketingDept1 to a user mailbox.
Set-Mailbox MarketingDept1 -Type Regular
You can use the following values for the Type parameter:
For detailed syntax and parameter information, see Set-Mailbox.
To verify that you have successfully converted the mailbox, run the following Shell command:
Get-Mailbox -Identity MarketingDept1 | Format-List RecipientTypeDetails
The value for RecipientTypeDetails should be UserMailbox.
For detailed syntax and parameter information, see Get-Mailbox.
