Microsoft Teams update: QR code protection for messages from external users
Microsoft Teams is adding extra security to protect users from phishing and fraud. QR code images sent by external users will be hidden by default. Users can choose to reveal the image before viewing or scanning the QR code. Rollout schedule Targeted Release: Beginning in October 2026 General Availability (Worldwide): Beginning in late October 2026 Impact on your organization Who is affected Organizations that allow communication with external users in Microsoft Teams. Users who receive Teams messages from external senders. Teams administrators and support teams that manage external collaboration policies. QR code images sent by external users will be blurred by default in Teams messages. Users can reveal the image if they trust the sender and want to scan the QR code. A blurred image does not mean the QR code has been identified as malicious. This protection will be applied automatically to QR codes received from external users. No admin configuration or policy changes are required. The feature will be enabled by default during the rollout. Action required and recommendations No admin action is required before rollout. Inform users that QR code images from external senders may appear blurred by default. Remind users to verify the sender before revealing or scanning QR codes. Review existing user education materials related to phishing awareness, QR code safety, and external collaboration. Update internal help desk documentation to reflect the new user experience. https://www.linkedin.com/feed/update/urn:li:activity:7520938452184408065/
Microsoft Teams transcription language settings
Hi! With a Microsoft 365 Business Premium license and a Copilot license, I can use transcription during a Teams meeting by setting the spoken language to Auto Detect. However, the transcription is sometimes inaccurate. Is there a way to limit the language detection scope? For example, is it possible that I select only English and Chinese, and Auto Detect is restricted to those two languages instead of also attempting to detect languages such as Spanish or French ?
Architectural Limitation: Move LBR from Gateway to Voice Routes for Shared Trunks
The Problem: Currently, Location-Based Routing (LBR) in Microsoft Teams is hard-locked to the root OnlinePSTNGateway object (e.g., via -GatewaySiteLbrEnabled). This creates two major administrative roadblocks: Derived Trunk Limitations: For organizations utilizing multi-tenant partner architectures and derived trunking models (such as AudioCodes Live Pro/Express), the underlying global gateway configuration is owned and managed by the provider. Because administrators lack root modification rights over these shared gateway objects, they cannot enable or configure LBR. https://imgur.com/a/RzTE4nu Managing gateways via the Teams Admin Center (Voice > Direct Routing > SBCs) results in restricted or failing LBR configurations. Rigid Global Enforcement: Forcing LBR as a strict hardware-level switch creates deployment roadblocks, such as entirely blocking unmapped or remote workers. This is overly restrictive in regions like North America, where strict anti-toll-bypass compliance is not a legal mandate (unlike regions like India). The Proposed Solution: Decouple LBR from the Gateway Object: Shift LBR evaluation away from the root hardware gateway switch toggle and allow it to occur at the Voice Route, PSTN Usage, or Calling Policy layer. Support Derived & Shared Trunks: This decoupling will instantly make LBR compatible with multi-tenant SBC models, allowing enterprises to manage geographic routing via distinct voice routes (which are already peered with gateways), bypassing the need for root gateway property access. Regional Flexibility & Compliant Enforcement: Enable regional flexibility so enterprises can bypass unnecessary toll-bypass blocks in regions where they aren't mandated (like North America) without breaking calls for "Unknown" network sites. Crucially, for heavily regulated regions like India, system-enforced policies should automatically lock LBR on to strictly maintain local country regulations without relying on manual overrides. Business Impact: This enhancement will unlock advanced routing flexibility for thousands of enterprises utilizing modern cloud-hosted and derived trunking architectures. It bridges the gap between legacy PBX design constraints and modern multi-tenant cloud voice management, significantly reducing deployment friction for global organizations.
Meeting setup in teams Channel is not allowing me to update the Agenda and send updates
I am interested to understand why when I have setup a meeting from A channel I am not able to change the invitation to all the team members. When I go into teams Calendar ,. I update the agenda description, the send updates at the top right view shows up when I do the changes , however , When I click it , the changes don't take effect.
Shared Channels: @Channel mentions fail to trigger activity notifications for team-shared members
Hello everyone, I am facing a persistent issue regarding notification behavior in Microsoft Teams Shared Channels that I hope someone can clarify or help with. Scenario: We have a Shared Channel that is shared with multiple teams (e.g., 17 teams in total). Note: I know that this way of communicating is not the recommended way, but we are not allowed to use any Viva products etc. Users accessing the channel are members of those shared-in teams, but they are not listed as direct individual members in the Shared Channel's own member list. Users have their channel notification settings correctly configured to receive notifications (e.g., "All new posts" or standard banner/activity settings). The Problem: When someone uses a channel mention (e.g., @ChannelName) in this shared channel, the users who have access via the team-sharing mechanism do not receive any activity feed notifications. The workaround/oddity: They only receive the activity notification if we explicitly add each user as a direct individual member to the Shared Channel. The dilemma: Since the channel is shared with 17 teams, adding hundreds of users manually or via scripts as direct members creates massive redundancy and clutters the UI (users see the team and the channel redundantly). Inconsistency: We noticed that in older shared channels created some time ago, channel mentions worked across team shares without needing direct individual memberships. It seems newer shared channels behave differently and strictly require direct membership to trigger activity feed notifications for @Channel mentions. Questions: Is this a known design limitation or a recent backend change in Microsoft Teams for newer Shared Channels regarding how @Channel mentions resolve indirect team members? How are organizations supposed to utilize @Channel mentions effectively in large-scale collaborations involving multiple shared teams without bloating the direct membership list? Any insights or workarounds would be greatly appreciated. Thank you!
Security loophole in Private Channels?
We came across an interesting use case in our organization today. We have a Team and a private channel within that Teams team. Within the private channel a subsite was created. I am not an owner or member of the Team nor am I a member or owner of the private channel. However during creation of the subsite I was able to be invited with unique permissions to the subsite and I was successfully able to access it. After the initial creation of the subsite, our admin was not able to add or remove or effect any additional permissions on that subsite. Is this a loophole? I expected that without being a member of the private channel I would have absolutely zero access to any items associated with the private channel and site. Which has remained true (when I go to the private channel URL I get denied access) except that I do have access to this specific subsite. My instinct is that the reason permissions cannot be changed after the fact is that this is a genuine loophole and permissions weren't intended by Microsoft to be able to be granted at all on the subsite. This is due to the fact it is under the private channel and permissions should only be able to be changed via the admin UI or from the Teams application. Has anyone come across this in their work? Any guesses or explanations for why the subsite access would be initially available? Is this just genuinely a loophole in the permissions architecture?
Cannot deploy Custom backgrounds for Teams in VDI environment
We have detected (or so we think) a malfunction in Teams on VDI when attempting to deploy Teams backgrounds that should be available to users for their video calls. The only article that documents how to do this is the following: https://learn.microsoft.com/en-us/microsoftteams/custom-meeting-backgrounds It clearly states that the path where custom Teams backgrounds are stored is in the user profile, specifically in the folder: %LOCALAPPDATA%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\Backgrounds\Uploads Expected Process The process is not direct, but it is straightforward. Using a script, a UUID is generated, which is used to create two image files (JPG, BMP, or PNG format, depending on the original image). For example, if the original is a JPG: UUID.JPG UUID_thumb.JPG These two files are copied to the path above, and on the next Teams session startup they should be available to the user. ✅ This works correctly in physical (non-VDI) environments. Tested many times without issues. What We Have Observed in VDI Even when the file pair is copied to the correct path within the user's FSLogix profile, the image does not become available in the Teams client — even after restarting Teams multiple times or even the VDI session itself. After each restart, the files are confirmed to be persistent and located at the correct profile path.[ %LOCALAPPDATA%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\Backgrounds\Uploads folder contents] When a background image is added manually through the Teams UI, a folder is created in OneDrive called "Microsoft Teams User Custom Video Backgrounds". If additional images are manually added to that OneDrive folder, they do not appear as available in Teams. This leads us to believe that the upload process performs additional operations in the registry or other configuration locations beyond simply copying the file. A ProcMon capture was performed, but after an initial superficial inspection, it was not possible to determine exactly what is happening under the hood.
Setting app page is not getting localized in windows server OS 2025 with official language pack ISO
We created a VM on ESXi with Windows Server 2025 and installed the language packs offline using the official language pack ISO for Windows Server 2025. Most of the UI was localized successfully, but the Settings app was not localized. We tested this with the Japanese language pack and also tried installing it using both PowerShell and DISM. Is this a known issue? Has anyone else encountered the same behavior? If so, is there any known solution?
