Email addresses aren't assigned correctly to new Office 365 mailboxes that you create in the Exchange Admin Center

PROBLEM

In a hybrid deployment of Microsoft Exchange Online in Office 365 and your on-premises Microsoft Exchange Server environment, you create a new Office 365 mailbox in the Exchange Admin Center. To do this, you select Recipients, click Mailboxes, click New (A screen shot of the New icon ), and then click Office 365 mailbox. However, when you take this action, email addresses aren't assigned to the mailbox according to the email address policies that are set. 

CAUSE

By default, the Automatically update email addresses based on the email address policy applied to the recipient setting isn't enabled when you create an Office 365 mailbox in the Exchange Admin Center.

SOLUTION

After you create a new Office 365 mailbox in the Exchange Admin Center, update the mailbox to use the email address policy. To do this, you can use either Exchange Management Shell or the Exchange Admin Center in the on-premises Exchange server. 

Use Exchange Management Shell

  1. Open Exchange Management Shell. For more information, go to the following Microsoft website:
  2. Run the following cmdlet:
    Get-RemoteMailbox <name of mailbox> | Set-RemoteMailbox -EmailAddressPolicyEnabled $True 

Use the Exchange Admin Center

  1. Open the Exchange Admin Center. 
  2. Select Recipients, click Mailboxes, and then double-click the Office 365 mailbox that you want to edit.
  3. In the left navigation pane, click Email address.
  4. Select the Automatically update email addresses based on the email address policy applied to the recipient check box.
  5. Click Save.
