O365 Delivery

Incident Report for SMTP2GO

Update

We are getting reports back from MS that show delivery is improving on a per IP basis. The full effect should be felt over the next 14 hours. In the meantime we recommend allowlisting our IP addresses. Below is a KB listing all the outbound ranges. If you have a dedicated IP, you will only need to allow list that one IP address.
