Latest Message<\/th>\nTitle: Users may be unable to access some Exchange Online archive mailboxes<\/p>\n

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

More info: This issue occurs when routine mailbox database maintenance for archive mailboxes relocates the archive to a different portion of Active Directory infrastructure from the primary mailbox. Impact may persist both during the maintenance move and after the move. The problem impacts archive mailbox access through any Exchange Online connection method.<\/p>\n

Current status: We’ve completed the validations of our secondary fix and we’re deploying it to our internal test environment to further confirm its’ ability to safely resolve this issue. We expect that this validation process may take until Wednesday, September 3, 2025. Once confirmed, we’ll begin deploying the fix to all affected users and will provide an estimated timeline for that process once available.<\/p>\n

Scope of impact: Any user attempting to access their Exchange Online archive mailbox while may encounter this issue if their primary and archive mailbox aren’t located on the same portion of Active Directory infrastructure.<\/p>\n
