Latest Message<\/th>\nTitle: Some admins may be unable to perform tenant to tenant migrations and offboarding moves in the Exchange admin center<\/p>\n

User impact: Admins may be unable to perform tenant to tenant migrations and offboarding moves in the Exchange admin center.<\/p>\n

More info: While we work on developing a long-term solution, admins may use PowerShell for the affected migrations and moves with the following cmdlet against the affected mailboxes:<\/p>\n

Set-MoveRequest “user@yourdomain.com&quot<\/a>; -SkipMoving FolderRestrictions<\/p>\n

Next, the tenant admin may resume the move request using the cmdlet: <\/p>\n

Resume-MoveRequest “user@yourdomain.com&quot<\/a>; <\/p>\n

This will allow the affected move jobs to continue to make progress.<\/p>\n

Admins may run the following PowerShell cmdlets sequentially for migration batches:<\/p>\n

Set-MigrationBatch batchname -SkipMoving FolderRestrictions
Start-MigrationBatch “BatchName”<\/p>\n

Admins attempting to complete a tenant-to-tenant migration or an offboarding move in Exchange Online will be returned the following error
“PropTagToPropertyDefinitionConversionException”<\/p>\n

Current status: During the initial deployment of our solution into our internal validation environment, our testing determined that while it would address most of the problems admins are experiencing, it wouldn’t resolve the problems for any non-signature moves, and thus not be viable for remediating the impact. We’re developing a new solution to ensure that all tenant to tenant and offboarding moves are restored for admins in the Exchange Online admin center and expect more clarity into the timeline for its deployment by our next scheduled communication update. <\/p>\n

Scope of impact: Some admins attempting to perform tenant to tenant migrations and offboarding moves in the Exchange admin center may be affected. This information may be updated as our investigation continues.<\/p>\n

Root cause: A change introduced a code regression to Mailbox Replication Service (MRS), which causes intermittent failures for tenant-to-tenant migration actions or offboarding moves as the property tags needed to complete the request are not being properly configured.<\/p>\n
