Office 365 Import Service: Get-MailboxImportRequest and Get-MailboxImportRequestStatistics

Office 365 Import Service (currently in Preview and free) can provide PST files import via network copy and it is a two-step process, from copying the files to Azure and then importing the PST into Exchange online. Recently I've described how to throttle traffic during PST upload to Azure Storage account. Now I'd like to document issues we've got during Import process (Mailbox Import Request):

There are two PowerShell cmdlets you can use to control import process: Get-MailboxImportRequest and Get-MailboxImportRequestStatistics:

PS > Get-MailboxImportRequest

If you will try Get-MailboxImportRequest | Get-MailboxImportRequestStatistics you will end with:

PS > Get-MailboxImportRequest | Get-MailboxImportRequestStatistics
Couldn't find a request that matches the information provided. Reason: No such request exists in the specified index.
   + CategoryInfo : NotSpecified: (:) [Get-MailboxImportRequestStatistics], ManagementObjectNotFoundException

If you have some job failed you can try to fix PST file with scanPST tool and upload it again to Azure. Just like an Exchange migration, PST Imports are limited to the number of failed or corrupt messages that can be skipped in the process. The number is over 200 for an Azure PST Import and appears to be around 218 items. Downloaded Error Report information would be something like:

12/23/2015 8:45:30 PM A missing item was encountered: Missing Item () Subject:"", Folder:"Calendar"
12/23/2015 8:45:30 PM A missing item was encountered: Missing Item () Subject:"", Folder:"Calendar"

12/23/2015 8:45:31 PM Fatal error TooManyMissingItemsPermanentException has occurred. 

After another try to increase limit of corrupted items we've ended with another frustrating error:

PS > Get-MailboxImportRequest -Status Failed | Set-MailboxImportRequest -BadItemLimit 500
WARNING: When an item can't be read from the source database or it can't be written to the destination database, it will be considered corrupted. By specifying a non-zero BadItemLimit, you are requesting Exchange not copy such items to the destination mailbox. At move completion, these corrupted items will not be available at the destination mailbox.

So what's wrong here? If you are going to use Set-MailboxImportRequest or Get-MailboxImportRequestStatistics or similar import cmdlets make sure you are using -Identity switch and RequestGuid value from Get-MailboxImportRequest.

PS > Get-MailboxImportRequestStatistics -Identity b132acbb-1272-4959-bdc5-ebe1e0f72b76

Name                                   StatusDetail            TargetAlias  PercentComplete
----                                   ------------            -----------  ---------------
1efae770-5acb-47a4-94c7-aa9df7197407   CreatingFolderHierarchy      ckepes              5

Next PowerShell commands will work for single ImportRequest:

Set-MailboxImportRequest -Identity b132acbb-1272-4959-bdc5-ebe1e0f72b76 -BadItemLimit 500
Resume-MailboxImportRequest -Identity b132acbb-1272-4959-bdc5-ebe1e0f72b76

Next PowerShell commands will work for the few ImportRequests:

Get-MailboxImportRequest | % {Get-MailboxImportRequestStatistics $_.RequestGuid}
Get-MailboxImportRequest -Status Failed | % {Set-MailboxImportRequest  $_.RequestGuid -BadItemLimit 500 | Resume-MailboxImportRequest}
