Tech Short: Office365 – Convert select on-premises mailboxes to mail-enabled users

When you convert on-premises mailboxes to mail-enabled users (MEUs), the proxy addresses and other information from the Office 365 mailboxes are copied to the MEUs, which reside in Active Directory in your on-premises organization. These MEU properties enable the Directory Synchronization tool, to match each MEU with its corresponding cloud mailbox.

Using the steps provided here I was able to export a list of only user mailboxes and leaving out other mailbox types

Run the following PowerShell command:

Get-Mailbox -ResultSize Unlimited -RecipientTypeDetails UserMailbox | Select PrimarySmtpAddress | Export-Csv -Path .\migration_users.csv -NoTypeInformation
