Host runtime requirements in your app manifest.Add Microsoft 365 channel for your appIn Microsoft Teams, a message extension consists of a web service that you host and an app manifest, which defines where your web service is hosted. The web service takes the advantage of Bot Framework SDK messaging schema and secure communication protocol through a Teams channel registered for your bot.For users to interact with your message extension from Outlook, you need to enable the Microsoft 365 channel for your Azure bot resource of the message extension app.NoteIf you've previously enabled the Outlook channel for your bot, you'll need to enable the Microsoft 365 channel for your message extension to function correctly in Microsoft Outlook. The Outlook channel is no longer used for message extensions running in Outlook and can be disabled.Go to Microsoft Azure portal or Bot Framework portal (if you've previously registered there), go to your bot resource.From Settings > Channels.Under Available channels, select Microsoft 365 channel.Select Apply.Confirm that your Microsoft 365 channel is listed along with Microsoft Teams in your bot's Channels pane.Update Microsoft Entra app registration for SSONoteYou can skip this step if you're building an app for Outlook using Teams Toolkit, as the scenario doesn't involve Microsoft Entra single sign-on authentication.Microsoft Entra single sign-on (SSO) for message extensions works the same way in Outlook as it does in Teams. However, you need to add several client application identifiers to the Microsoft Entra app registration of your bot in your tenant's App registrations portal.Sign in to Azure portal with your sandbox tenant account.Select App registrations.Select the name of your application to open its app registration.Select Manage > Expose an API.In the Authorized client applications section, ensure all the following Client Id values are listed:Microsoft 365 client applicationClient IDTeams desktop and mobile1fec8e78-bce4-4aaf-ab1b-5451cc387264Teams web5e3ce6c0-2b1f-4285-8d4b-75ee78787346Microsoft 365 web4765445b-32c6-49b0-83e6-1d93765276caMicrosoft 365 desktop0ec893e0-5785-4de6-99da-4ed124e5296cMicrosoft 365 mobiled3590ed6-52b3-4102-aeff-aad2292ab01cOutlook desktopd3590ed6-52b3-4102-aeff-aad2292ab01cOutlook Web Accessbc59ab01-8403-45c6-8796-ac3ef710b3e3Outlook mobile27922004-5251-4030-b22d-91ecd9a37ea4Upload your custom app in TeamsUpload your updated message extension (app package) into Teams.

What is the Website tab?The Website tab allows you to pin and load a website in a Teams chat or channel. You can do this today by clicking on the plus (+) button in a chat or channel on the Teams desktop or web app. After selecting the “Website” app, you will be asked to give your tab a name and enter a URL. Once the website is pinned, you can see the website loading in the Teams app.The website tab is different from the Teams tab apps in which developers can embed webpages in Microsoft Teams, Outlook, and Microsoft 365 using the Teams JavaScript client library.What are the upcoming changes for Website tabs?Starting July 2024, Microsoft Teams will be changing how the Website tab works in the new Teams client. Instead of loading the website link inside Teams, we will be opening the website link in a new browser tab. This is to better align with emerging best practices in web security and privacy while also improving the reliability of websites opened through this feature.Why are we making this change for the Website tab?The new Teams app was designed to use web standard best practices and to provide the recommended security and privacy that comes with it. Both the classic and new versions of Teams rely on the powerful and flexible Chromium rendering engine to power these experiences and to embed Website tabs. However, the underlying web standards in Chromium are evolving [1] to provide better security to these websites that are being embedded in Teams. Because of this, many websites are preventing themselves from being embedded in other sites, such as Teams, for valid security and privacy reasons. Users will see a blank screen when this happens but can choose to click the “Open in browser” button in the banner to open the website in a new browser tab [2].This does not occur for Teams tab apps, such as the Planner, SharePoint Pages or Jira apps, etc., because they are built on the Teams Platform using our developer tools to provide secure experiences to end users.What’s the new upcoming experience?Due to changes to the underlying web standards, we are changing how the Website tab works to better evolve with changing web standards. Instead of opening links inside the new Teams desktop or web app, we will be opening these links in a new browser tab instead. The Website

Hi all,My name is Koen and I am working with Microsoft Teams in a Dutch government organization. We like to offer our staff the ability to work from home, especially during the COVID-19 crisis. We already have enrolled Microsoft Teams in our desktop (it came out of nowhere and we are replacing the default web-downloader with the MSI file)For the record: We are using a non-persistent environment with VMWare Horizon Client and thin clients in the office, and mostly the web client when users are working from home.All of our users are having a profile where we store the temp files like caches and stuff. Also %AppData% is located in that profile. This data is presistent and will be availible on every boot, when they authenticate. But, we are looking for a way to change the Microsoft Teams cache location. We have limited disk space on the 'profile' disk. The problem is, that Microsoft Teams uses the folder %AppData%\Microsoft\Teams\Service Worker\CacheStorage as location of some caching files. The size of the folder is at least 200MB, and some other users are having a folder with at least 500MB cache. We have 200+ users, so when I calculate this ( 200(users)x200(MB) : 40.000MB/40GB for only the smallest caches. And the profile disk is only 100GB (for example)This is why we want to replace (or totally disable) the cache.I already looked in the newest Administrative Templates (for Office 365, 2016 and 2019) and the desktop-config.json - but I can't find the right way to do this.Does anyone know how to solve this issue?
