We are aware that some Netlify Support email responses to customers using Microsoft 365 and Outlook-hosted mailboxes are experiencing delivery delays. These delays appear to be related to an ongoing Microsoft Exchange Online service disruption, with some messages being temporarily deferred by Microsoft's mail servers. Our Support team continues to process and respond to tickets, but affected customers may experience delays receiving our replies. We are monitoring email delivery and will provide an update as Microsoft's service recovers.
