Re: Cutover Migration from Exchange 2016 to 365 - MigrationProvisioningPermanentException
A cutover Exchange migration doesn't support using a CSV file because all on-premises user mailboxes are migrated to Microsoft 365 or Office 365 in a single batch. https://learn.microsoft.com/en-us/exchange/mailbox-migration/csv-files-for-migration74Views0likes0CommentsRe: Cutover Migration from Exchange 2016 to 365 - MigrationProvisioningPermanentException
Quick update: The issue persists with several cutover migrations from German-language Exchange 2016 installations. We have since learned that the error is not unique to us. We would also like to point out that we and others have successfully completed numerous cutover migrations in the past. The cutover migration was started and completed as described here: https://learn.microsoft.com/en-us/exchange/mailbox-migration/cutover-migration-to-office-365 We are in contact with Microsoft Support. The cause of the issue is still unknown.64Views0likes0CommentsCutover Migration from Exchange 2016 to 365 - MigrationProvisioningPermanentException
We currently have several cutover migrations from Exchange 2016 to Exchange Online that result in the error message for all mailboxes: Error: MigrationProvisioningPermanentException: The operation couldn't be performed because object 'DEUxxx.prod.outlook.com/Microsoft Exchange Hosted Organizations/name-of-tenant.onmicrosoft.com/m.check' couldn't be found on 'FRxxx.DEUxxx.prod.outlook.com'. --> The operation couldn't be performed because object 'DEUxxx.prod.outlook.com/Microsoft Exchange Hosted Organizations/name-of-tenant.onmicrosoft.com/m.check' couldn't be found on 'FRxxx.DEUxxx.prod.outlook.com'. m.check is a test/dummy account. The migrations are performed as described here: https://learn.microsoft.com/en-us/exchange/mailbox-migration/cutover-migration-to-office-365 https://learn.microsoft.com/en-us/exchange/mailbox-migration/decide-on-a-migration-path#exchange-2010-2013-or-2016 When the migration batch is started in Exchange Online, the tenant is new and empty (except for one admin account). After starting the batch, we see that the mailboxes and user accounts are being created. After a few minutes, the error message appears for all mailboxes. For example, the information via PowerShell for a test account: Get-EXOMailbox -Identity ‘M.Check@…’ ExternalDirectoryObjectId: 021814bc-361c-4029-84ea-f8fbad37675a UserPrincipalName : M.Check@...

Of course, we don't rule out the possibility that the error lies on our side. But we don't currently see it. Some information about the error message can be found in the context of migrations from Google to Exchange Online. Inquiries to Microsoft have not yet yielded a response. Does anyone have an idea/approach? Thank you! Dieter Santesson228Views0likes3Comments
