Dear Valued customers,
A worldwide Microsoft 365 incident (Microsoft reference EX1550543), which began on Thursday, November 12, is affecting Exchange Online. As a result, emails sent by our AI Agents may be delayed or not delivered, and replies sent may not reach us.
Microsoft has identified the cause and is reverting a recent configuration change while applying further fixes. Its latest update reports recovery in progress across regions, but service health remains variable and capacity has not fully returned to normal. Until Microsoft's recovery is complete, AI Agent email delivery may be inconsistent. Once Microsoft services recover, you may see a surge of delayed emails.
