Exchange 2010 -> 2016 Public Folder migration - ERROR: MapiExceptionJetErrorTableDuplicate

Question

Hello,

I have a migration issue where the migration crashes to 15 percent and then reports a MapiExceptionJetErrorTableDuplicate error. Using the command:
Get-PublicFolderStatistics -ResultSize Unlimited | Where {($ _. Name -like "* \ ") -or ($ _. Name -like " / *")} | Format-List Name, Identity
I only get system public folders

Name : EX:/O=ORGCORP/OU=EXTERNAL (FYDIBOHF25SPDLT)
Identity : 000000001A447390AA6611CD9BC800AA002FC45A03003068891511E94749BB7AD4FF52FEC2280000000004160000

Don't I need to edit these folders?

Any idea where the problem might be?

thank you very much for your help

Hi @HanakJ

Using the command: Get-PublicFolderStatistics -ResultSize Unlimited | Where {($ . Name -like " \ ") -or ($ . Name -like " / ")} | Format-List Name, Identity

Since you are migrating to Exchange 2016, I think migrating these system public folders isn't necessary.
Because Exchange 2016 will use the availability service for free/busy information and only use web-distribution for Offline Address Book.

Have you checked the following two links in the similar situation?
Public folder migration from 2010 to 2016 failed with "Transient error MapiExceptionJetErrorPageNotInitialized has occurred"
Public Folder Migration - MapiExceptionJetErrorTableDuplicate

According to the answers, the possible cause of this issue may be some corruption in the public folder database.
