Microsoft to Drop Most Azure Communication Services

Azure ECS and HVE Services.

Microsoft has announced that it will retire most Azure Communication Services offerings on September 30, 2028. Among the affected services is Email Communication Services (ECS), leaving Microsoft without a dedicated cloud service for high-volume external email. Exchange Online’s High Volume Email (HVE) service currently lacks that capability, but Microsoft could choose to fill the gap with a new pay-as-you-go HVE offering aimed at bulk email workloads.

Microsoft Cancels Exchange Mailbox External Recipient Rate Limit

Exchange Mailbox External Recipient Rate Limit Canned.

After considering customer feedback, Microsoft cancelled the mailbox external recipient rate limit for Exchange Online. The idea behind the new limit was simple – it makes life more difficult for spammers to use Exchange Online as a platform. Unhappily, customers didn’t like losing the ability to send relatively small amounts of external email for different reasons. C’est la vie.
