Microsoft announced Agent 365 back in November 2025 at the annual Ignite conference. Right after the announcement, a trial version of the Agent 365 licenses was made available. A lot has changed since and this can lead to confusing experiences for customers. Such as this recent notification email saying “Your organization’s Microsoft 365 Frontier for AI teammates subscription has expired”:
To understand the situation better, let’s revisit what I wrote about Agent 365 licenses back in November. On the week of Ignite 2025, anyone could sign up for the preview and get 25 units of what was called Microsoft Agent 365 Frontier licenses available in their tenant. As the ToS dialog from that experience illustrates, there licenses were not meant for human users but AI agent instances only:
Later, we learned about the commercial strategy that Microsoft had landed on for the May 1st GA of Agent 365. Instead of licensing the product per agent, it was packaged into the hero SKU of Microsoft 365 E7 Frontier Suite at the sweet price of $99. You could also buy it separately, at $15 per user.
This caused confusion, especially since in their own Agent 365 product pages, Microsoft had earlier said that A365 will give tools like M365 apps (Word, Excel, Outlook) to the licensed agents. Then, at GA, these had disappeared and now Agent 365 was only about governance and observability. The explanation is that only a part of Agent 365 actually became generally available in May 2026. This earlier post covers the details:
In short, the A365 SKU launched alongside E7 was never going to provide all the agent tooling needed. Since there must have been immense commercial pressure for the M365 E7 hero SKU to be made available for MS sellers to meet their FY26 quotas, the per-user part was launched before the per-agent features were ready.
The Frontier program for Agent 365 has been said to continue alongside the GA part, covering especially the autonomous AI agents that are not tied to human worker identities. Initially, the trial license was extended all the way to December 2026. Or more specifically, a new license “Microsoft Agent 365 Frontier (no Teams) was silently issued in March for tenants participating in the preview program:
Now, in June 2026, that SKU appears to have been renamed “Microsoft 365 Frontier for AI teammates”. If we go to M365 Admin Center and open the license assignment UI, we can see the list of service entitlements included with this license:
There is no official documentation mentioning this new product name yet, apart from the single instance of it on the MS Learn page “Preview Microsoft Agent 365 features through the Frontier program”.
I don’t think Microsoft would have accidentally dropped the “Agent 365” part from this SKU name. Instead, it serves as further evidence that in addition to the Agent 365 licenses sold for all human users of the tenant, the AI teammates operating with their own identity will require an M365 style license of their own. This would be perfectly in line with Satya Nadella’s earlier statements of the future of Microsoft’s licensing model being about both per user and per agent:
These frequent changes in product naming and licensing terms indicate that the detailed implementation model of how to make that vision a reality is still being worked on. It can lead to surprises like the Agent 365 licensing terms being updated with new prerequisites only one month after GA, making M365 E5 level security features a requirement for eligibility to buy A365 licenses.
For Microsoft customers, there are more AI related licensing challenges to tackle than just Agent 365. The recent GA of Copilot Cowork introduced a new dimension of consumption-based licensing via Copilot Credits (see my online calculator at cowork.licensing.guide) that further increases the need for proactive planning in this space. As always, if you need one-to-one advisory on the Microsoft licensing topics, please do reach out and let’s have a chat.
