Microsoft is experiencing a service disruption affecting Exchange Online / Outlook.com. This may affect Maileon customers as follows:

Email delivery: Emails sent to Microsoft-hosted mailboxes (e.g., Outlook.com, Hotmail, Microsoft 365 business accounts) may be delayed or temporarily deferred. Deferred messages will be retried automatically. Login / two-factor authentication: Users who receive their Maileon verification codes at an affected Microsoft mailbox may receive them late or not at all. If you cannot log in, please try again later or contact our support.

The issue originates in Microsoft’s infrastructure and is not related to Maileon. All Maileon systems are fully operational. We are monitoring the situation and will update this page as it develops.
