Migration status report - Error code 400

Question

Hi,

I'm trying to migrate few users from on-premise Exchange servers to O365. Exchange server is running in hybrid mode and I'm trying to access the Migration status/error reports. Basically both reports comes up with Error 400 - Missing or invalid query parameter when I attempt to download the report either from the Hybrid CP dashboard/ on-premise EAC dashboard or following the link from the e-mail box itself. The account I'm using has full permissions everywhere (both on-premise and cloud). Any help?

I'm not entirely sure why the migration itself fails eventhough the EWS tests from https://testexchangeconnectivity is successful.

Hi ExchBin,

Generally, admins can follow the steps in the link below to move users between on-premises and Exchange Online organizations in hybrid deployments.

Move mailboxes between on-premises and Exchange Online organizations in hybrid deployments

You can also use Troubleshooting migration issues in Exchange hybrid environment to check it.

If the issue persists after you try the steps in the link, I’d like to collect some information:

1.    I noticed that you had another thread and did the hybrid with multip-forests. May I know whether which forest you want to move to cloud? Can you provide more detailed steps?

2.    Do you use Exchange 2010 or 2013?

3.    Can you provide me with information on the average size of the mailboxes which are part of this migration batch?

4.    Please run the following PowerShell commands and provide the results.

Get-MigrationUserStatistics -Identity ******@domain.com | fl

Get-MigrationBatch -Identity "MigrationBatchName" | fl

Get-MigrationStatistics | fl

Get-MoveRequest -identity <name of the migration request> |fl

Get-MoveRequestStatistics -Identity “Email address“ -IncludeReport -Diagnostic -DiagnosticArgument verbose | Export-CliXml UserReport.xml

Hi ExchBin,

I understand that you have encountered issue when trying to download the migration error reports, and I have also checked the screenshots you included in the file you sent to Erick.

From one of the screenshots, I can see an error saying “Report might have been moved or deleted”, and the affected browser is Internet Explorer. I want to know if you have tried another browser to download the report. Does the same error occur to other browsers too?

Moreover, you can try if this KB could help you with the error from your Internet Explorer.

And about “why the e-mail reports are not accessible”, I do not see the screenshot after you click the download link in the email report. Can you please provide one?

Thanks,

Allen

Hi,

Thanks, my problem is not the migration itself. While I can look at the cmdlets output and troubleshoot the issues, on a large scale migration, running this for huge number of users would be a challenging task. I'd like to know why the e-mail reports are not accessible or the link from the migration dashboard comes back with an error message.

Hi ExchBin,

Sorry for the delay and thanks for your information in the private message.

Based on your error message (“A recipient wasn‎'t found for "*** Email address is removed for privacy ***" on the target. Create a recipient of the appropriate type for this migration on the target and try again”), I’d like to share a workaround. Please try the steps below:

1. Run Get-Mailbox -SoftDeletedMailbox to list the deleted mailbox users. If the affected users are included, run Remove-Mailbox -PermanentlyDelete to completely remove them.
2. Run Get-MailUser -Identity <user> | FL GUID to get the GUID of the user.
3. Run New-MoveRequest -Identity <GUID> -Remote -RemoteHostName 'mail.domain.com' -RemoteCredential $cred -TargetDeliveryDomain 'domain.mail.onmicrosoft.com' -BadItemLimit 10 -LargeItemLimit 20 to try a new batch to move the mailbox.

Note: please replace all the domain names included in the commands above.

Meanwhile, if this cannot work either, please choose an affected user and run Get-Recipient -Identity "Email address" | FL from both Exchange Online and Exchange on-premises. After that, you can provide the result in the private message.

Best Regards,

Erick
