Microsoft Teams August 2025 Updates

I typically forget to look at the monthly Microsoft Teams blog posting they do every month.  There are always several new features can capabilities being introduced each month.  Here are a couple that caught my eye.

• New filtering for messages in chat and channels.
• Save messages view.  You have the ability to bookmark important chat messages and go to a centralized view that will show you everything you have booked marked across Teams chats.
• Multiple emoji reactions….yes I can finally many, not just one.
• Personal meeting templates allows you to create meeting templates that are based on your preferences for external meetings, internal 1:1 meeting, partner meetings, etc.
• Organizers can now message attendees in the lobby before letting them in.  For instance, “hey we will let you admit you in 2 mins we are running late”.

Microsoft Copilot Chat now has GPT-5

GPT-5 is now integrated into M365 Copilot, representing a notable advancement and fulfilling Microsoft's commitment to incorporating the latest OpenAI models into M365. With GPT-5, Copilot can process prompts using a real-time router that selects the most appropriate model to generate a response. Furthermore, Copilot is designed to deliver rapid replies for efficient user experience. For complex and open-ended inquiries, Copilot identifies when advanced reasoning is necessary and utilizes GPT-5’s enhanced reasoning capabilities.

M365 Copilot Memory

M365 Copilot continues to evolve with new capabilities. M365 Copilot Memory will be introduced in July 2025 and will be enabled by default. This feature allows Copilot to retain key information about users, such as preferences, working styles, and recurring topics, thereby tailoring responses accordingly. Copilot will analyze relevant details and interactions to understand user preferences and requirements. Additionally, users can instruct Copilot to remember specific items of interest and define desired interaction styles, such as requesting more formal communication. These enhancements are designed to further improve the assistant's usefulness.

Users maintain control over their data, with the option to disable memory, as well as view, edit, or delete individual memories at any time.

Furthermore, memory training is available. Users may prompt Copilot to ask questions—such as five questions regarding writing style or ten questions covering workplace preferences—to refine its understanding and responsiveness.

M365 Copilot Chat GCC Release

Microsoft Copilot Chat is now available in the GCC cloud and has been rolling out, with completion expected by the end of June 2025. This release provides Copilot Chat to all users without requiring an M365 Copilot Add-on license.

By default, web-grounding is turned off in GCC tenants. If web-grounding is enabled, users can use Copilot Chat with data from the Internet. The query leaves the GCC boundary, but all necessary internet data required by Copilot to provide a response is brought back and processed within the GCC compliance boundary. Therefore, the risk for organizations is minimal and comparable to users using a public Internet search engine to find answers. Additionally, organizations may benefit from increased security as all user interactions with Copilot Chat are discoverable and comply with Microsoft’s Enterprise Data Commitments.

If web-grounding remains disabled, users will still have access to a basic ChatGPT offering with Copilot Chat. Users can utilize files with Copilot Chat, but no additional Internet data will be available. Users are limited to a maximum file size of 512 MB per uploaded file and a maximum of three file uploads per day.

New M365 Copilot Tuning

Microsoft 365 Copilot Tuning is a new feature currently in preview. Microsoft 365 Copilot's large language model (LLM) is a general model used by all Microsoft 365 tenants. This LLM is not specific to any customer, and it is not a learning model. When users interact with Microsoft 365 Copilot, the general LLM along with Microsoft 365 data is used to generate responses. While this setup functions adequately, the responses are not entirely tailored to an organization's unique knowledge or approach.

With Microsoft 365 Copilot Tuning, users can now create fine-tuned models that perform domain-specific tasks related to their organization's knowledge. These models can be trained on a subset of data, such as authoritative documents in a library. Once created using domain-specific data from your tenant, these models can be utilized by a Copilot Studio agent. The tailored model remains within your tenant and does not revert to the generic Microsoft 365 Copilot LLM. Therefore, results provided by an agent leveraging a fine-tuned model created with your organization’s data will be more accurate and comprehensive. These models are low-code solutions that are straightforward to create using Copilot Studio.
