Solution

To resolve this issue, follow these steps:
  1. Connect to Exchange Online in Office 365 pre-upgrade by using�remote PowerShell. For more information about how to do this, go to the following Microsoft website:
    Connect to Exchange Online Using Remote PowerShell
  2. Run the following cmdlet to collect information about the user. This includes the user's primary email address and distinguished name. This example collects information about john@contoso.com.
    Get-mailbox john@contoso.com | FL DisplayName,PrimarySmtpAddress,Name,DistinguishedName
    Here's an example of what the output of the cmdlet might look like:
    DisplayName: John Smith
PrimarySmtpAddress: John@contoso.com
Name: Admin@contoso.microsoftonline.com
DistinguishedName:CN=Admin@contoso.microsoftonline.com
    Note In this example, the output shows that the user's PrimarySmtpAddress parameter differs from the Name parameter.
  3. If the output of the cmdlet shows that the PrimarySmtpAddress parameter differs from the Name parameter, start the Windows Azure Active Directory Module for Windows PowerShell, and then run the following cmdlet to change the user's user principal name (UPN) so that it's the same as the PrimarySmtpAddress parameter. 
    Set-MsolUserPrincipalName -UserPrincipalName John@contoso.com -NewUserPrincipalName John@contoso.com
    After you change the user's UPN, it may take 15 minutes for the changes to propagate and take effect.
