This mailbox exceeded the maximum number of corrupted items that were specified for this request

While trying to migrate mailboxes to Office 365 within a Hybrid configuration, we have run across this error:

This mailbox exceeded the maximum number of corrupted items that were specified for this request”

 

The default number of ‘corrupted items’ or ‘large items’ is 10 per mailbox. Once this is reached,  the migration will fail.

You can overcome this problem by 2 ways:

1- Run the migration from the Office 365 portal:

  1. Open the Office 365 portal and browse to the Exchange Admin Center
  2. choose Recipients
  3. Then choose Migration
  4. Then press press on the + sign
  5. Choose migrate to Exchange Online then press next as below1
  6. Choose Remote move migration then next
    2
  7. Then select the users you want to migrate , press the  + sign
    3
  8. Search for the user ,choose it then press ADD
    4
  9. In the next page , just press next
    5
  10. Choose the name of this migration
  11. Choose the domain , by default it will be domainame.mail.onmicrosoft.com
  12. You can move the mailbox and its archive or only move the archive
  13. Then you can decide the number of the Bad Item and the large item limits
    6
  14. Choose the recipient to receive the alerts and reports related to this migration batch
  15. You can start to start this migration patch manually or automatic
  16. You can also decide to finalize this script manually or automatic
  17. Then press new
    7
  18. You can now watch the migration batch Syncing or Completed
    8

 

2- The other way to do that is using the Power shell commands

  1. Find Power Shell ,right click to ‘Run as Administrator
  2. $cred = Get-Credential ( Enter your Office 365 credentials)
  3. $s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic -AllowRedirection
  4. $importresults = Import-PSSession $s -AllowClobber
  5. $RemoteCredential= Get-Credential (Enter your on premise Exchange credentials)
    1. New-MoveRequest -Identity <username or mailbox identity here> -Remote -RemoteHostName <hybrid Exchange FQDN> -TargetDeliveryDomain <your target domain e.g. domainname.mail.onmicrosoft.com> -RemoteCredential $RemoteCredential -BadItemLimit 999 -LargeItemLimit 999
