Latest Message<\/th>\nTitle: Some users may be unable to access specific archive mailboxes<\/p>\n

User impact: Users may be unable to access specific archive mailboxes.<\/p>\n

More info: Specifically, during an archive mailbox cross-forest migration, some users may be unable to access the online archive mailbox when the primary mailbox is located in a different Active Directory forest from the archive mailbox.<\/p>\n

Current status: Our server-side fix to update the method that users\u2019 cache is generated upon loading the affected mailboxes has completed and saturated to affected environments, but also revealed additional code discrepancies that will need to be addressed by our supplementary fix. To ensure complete remediation, the internal validations for our secondary fix’s deployment has been delayed to allow for additional review and testing so we can ensure it doesn’t produce any unexpected problems in the service. We aim to provide a timeline for our secondary fix deployment and the remediation of impact at the time of our next scheduled update.<\/p>\n

Scope of impact: Some users attempting to access specific archive mailboxes during a migration may be impacted.<\/p>\n

Start time: Monday, June 23, 2025, at 1:00 PM UTC<\/p>\n
