Mailbox originally created in Exchange Online
1. Start the EMC on your on-premises Exchange hybrid server or management
computer.
2. Check if the ExchangeGUID property on the on-premises remote mailbox is set by
entering the following command. Figure 12-35 shows an example of the output as a
result of issuing the command:
Get-RemoteMailbox <alias of cloud mailbox to migrate back on-premises> |
Format-List ExchangeGUID
Figure 12-35 Checking the value of ExchangeGUID .
3. If the return value for ExchangeGUID is not all zeros, as shown in Figure 12-35, then
ExchangeGUID is set. You can immediately initiate a remote mailbox move back to
on-premises Exchange by following the steps outlined in the “Mailbox originally
created on-premises” section.
4. If the return value for ExchangeGUID is all zeros, then ExchangeGUID is not set. On a
separate computer, start the Windows Azure Active Directory Module for Windows
PowerShell and connect to Exchange Online. Do not use the Exchange Management
Shell. As a reminder, you can use the following syntax to connect to Exchange Online
through remote Windows PowerShell:
Import-Module MSonline
$cred = Get-Credential
Connect-MsolService -Credential $cred
$Session = New-PSSession -ConfigurationName Microsoft.Exchange-ConnectionUri
https://ps.outlook.com/powershell/ -Credential $cred -Authentication Basic
-AllowRedirection
Import-PSSession $Session -AllowClobber
5. Enter the following command to retrieve ExchangeGUID for the Exchange Online
mailbox, and write down the returned value:
Get-Mailbox <alias of the cloud mailbox to migrate back to on-premises> \
Format-List ExchangeGUID
