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: Our validation efforts are taking longer than initially anticipated, and we’re continuing to verify the efficacy of our secondary fix within our testing environment for an extended period. We expect to have a more substantial update by Thursday, September 25, 2025, and will provide an updated timeline as one becomes available.<\/p>\n

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

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