| MC1048624 | (Updated) DNS Provisioning Change | Updated October 2, 2025: We have updated the timeline. Thank you for your patience. We're making some changes to DNS provisioning of A records for all new Accepted Domains provisioned after February 1st, 2025 (previously October 1st).

| MC1226222 | (Updated) Prevent/Fix: Guidance for On-Premises Connectors Configuration | We are reiterating the guidance for connector settings to ensure customers are using healthy configurations. The key problematic configurations we are seeing are: When a tenant has an Inbound connector of type OnPremises and the connector does certificate-based authentication using a certificate with a subject/SAN for a domain that is NOT an Accepted Domain of the tenant. When a tenant has an Inbound connector of type OnPremises and the connector does IP-based authentication, but the IP is used by other tenants. These anti-patterns typically occur when you are using a 3rd party service to relay email through Exchange Online but could also occur if your organization has a single on-premises Exchange Server connecting to multiple Exchange Online tenants. These configurations can cause incorrect mail flow because Exchange Online is a multi tenant service and relies on message attribution to determine which tenant an incoming message belongs to. When messages are received through an Inbound connector of type OnPremises, attribution is determined using the following priority order: The domain on the TLS certificate presented by the sending server The P1 MailFrom (envelope sender) domain The P1 RcptTo (recipient) domain |
