SSO for a Python Teams Bot (M365 Agents SDK + FastAPI) — Single-Tenant, Multi-Tenant, and UAMI
We're building, a Teams bot (Python / FastAPI) that uses the M365 Agents SDK (microsoft-agents-hosting-fastapi + microsoft-agents-authentication-msal, v0.8.0) with a CloudAdapter and MsalConnectionManager. The bot is currently scoped to personal only and runs behind an Azure Bot resource. We are trying to implement SSO to authenticate users, so far we are not successful. The main blocker is that we failed to authenticate users from tenant different than the Azure Bot resource of our app. If anyone has successfully managed to authenticate users on Teams using a setup similar than ours please do share your experience. We would love to learn from your experience. So far this was our main source of documentation: https://learn.microsoft.com/en-us/microsoftteams/platform/bots/how-to/authentication/bot-sso-overview Many thanks
Teams - Camera and screen share issue
Hi, Since yesterday we have been having firm wide issues with camera usage and screen share in Teams calls. When user 1 calls user 2, user 1 can see user 2s camera and screen share. User 2 cannot see user 1s camera or screen share. It seems to be that the recipient cannot see camera feed or screen share, but the original caller can see incoming camera feeds and screen shares. We have tried fully reinstalling and nuking local cache, but no luck. Before we start looking a bit deeper, has any others had this at all. Many thanks guys
Teams Planner Duplication
Does anyone know if you can duplicate Microsoft Teams Planners for onboarding tasks? I am trying to create an easily replicable Teams Planner with links to files in Sharepoint folders, for example. I want to be able to copy this planner for each new hire and have a copy of all the files and planner tasks in the new copy. Any advice or expertise would be much appreciated!External sharing recommendations?
Our Teams environment is fairly restrictive when it comes to external sharing. We do not permit OneDrive external sharing, and Teams sharing is disabled except for guest accounts that IT creates. That has become a bit of a pain when we need to provide access to external entities that might need just a one-time access for files. Creating a guest account for a one-time/short-term use takes time and seems administratively cumbersome. Anyone have any suggestions for these sort of needs?
Group email addresses for Teams sometimes contain “+” or “/” characters
We are using Microsoft Teams in our organization. When creating multiple Teams with exactly the same team name, using ASCII alphanumeric characters only, we occasionally see that the automatically generated group email address contains unexpected characters such as “+” or “/”. I would like to know whether this behavior is expected or if it is specific to our environment. This issue seems to have been occurring since around August 2025. We manually create Teams using the Windows Teams client. For example, if we create several Teams with a simple name such as “example2026”, the corresponding group email addresses are generated in the following format: email address removed for privacy reasons However, in some cases, the XXXXXX portion includes characters like “+” or “/”. When creating around 50 Teams, this issue appears in a few of them. This causes two problems for us: A “+” character interferes with plus-addressing behavior. When a “/” is included, we cannot create events inside the Team. Has anyone else encountered this issue or knows why this happens? Any insights would be appreciated.
Student chat disabled?
Hi there, I’ve started testing and setting up Teams for my education customer. I’ve gotten reports that teachers have a “This chat has been disabled. You can’t send send a message , but can view past messages.” Message when going to message a student. I have tried re-assigning policies but nothing that I’ve tried has worked. Any resolutions? Help is greatly appreciated. Thanks, Jessie M. Hadaller EDIT: This issue only appears on the iPad app version of Teams. Version#:3.10.0Best External Access configuration
I’m looking for guidance on the best Microsoft Teams configuration for the following goal: Objective Prevent random external domains from: Looking up users in Teams Sending 1:1 chats Making direct audio/video calls At the same time: External users invited to Teams meetings should not appear as AnonymousUpcoming change: disabling Teams meeting recording expiration notification emails
Hello, We wanted to share an important update regarding email notifications for expired Microsoft Teams meeting recordings. Based on valuable feedback from our community, we’ve decided to make a change to how notifications are handled. What’s changing: Starting June 1st, we will stop sending email notifications for expired Microsoft Teams meeting recordings. We are making this change due to complaints we received from many customers about the high volume of notifications which they deemed low value. This change allows us to respect your preferences while ensuring critical communications remain accessible. Recording expiration and deletion policies remain unchanged and items that expire will be deleted even when notifications are not being sent. How to keep receiving notifications: For those customers that would like to continue receiving email notifications, we will create a new setting and make it available before June 1st. This will be a per-tenant setting. We will send another message center post once this setting is available and update our documentation in this discussion and on our support page. After June 1st: If you didn’t change notification settings before the deadline, you can still re-enable them at any time by running the PowerShell command. Note: Our original message center post incorrectly asked recipients to fill out a survey and failed to include a link to the survey. We are committed to providing options that work for your organization, and we would like to hear from you. If you have questions or additional feedback about this change, please complete this survey and join the discussion: Teams Meeting Recording Notification Changes – Fill out form Thank you for being part of our community.
