Latest Message<\/th>\nTitle: On-premises and tenant-to-tenant mailbox migrations initially fail to complete, then complete after restarting<\/p>\n

User impact: On-premises and tenant-to-tenant mailbox migrations initially failed to complete, then completed after restarting.<\/p>\n

Final status: Our telemetry shows that instances of this issue occurring after our fix have significantly dropped and this issue is resolved. While this issue was primarily affecting a specific folder, in which our fix was applied to address, there are some rare instances where other folders may see this error and be impacted. Due to the infrequent nature of this, the errors potentially affecting different folders cannot be predicted, and we recommend reaching out through our support channels for additional assistance. Please note that while the errors may occur, migrations are still expected to complete after the restart is done.<\/p>\n

Scope of impact: This issue may have impacted any admins doing on-premises or tenant-to-tenant mailbox migrations.<\/p>\n

Start time: Tuesday, April 18, 2023, at 10:00 AM UTC<\/p>\n

End time: Thursday, April 27, 2023, at 12:00 AM UTC<\/p>\n

Root cause: A recent change altered the source where the migration service selects a specific folder for copying during migrations, causing the incorrect folder to be selected and the copy job failing.<\/p>\n

Next steps:
– We\u2019re reviewing our validation and update procedures to detect and prevent issues like this prior to deployment in the future. <\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
