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: Validation of a server-side fix to change to the way the user cache is generated upon loading the affected mailboxes is complete and has begun deploying. Validation of a second client-side fix, on which mitigation for Outlook on the web is dependent, is progressing. We’re continuing to confirm the efficacy of the client-side fix, and we’ll provide a timeline for deployment once this process is complete.<\/p>\n

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