New Teams Download Link has changed from MSTeams-x64.msix to MSTeamsSetup.exe between 17/8/24 and 11/9/24

Question

On https://www.microsoft.com/en-us/microsoft-teams/download-app we were able to download MS Teams desktop app for Windows devices which pointed to MSTeams-x64.msix on statics.teams.cdn.office.net/production-windows-x64/enterprise/webview2/lkg/MSTeams-x64.msix this was causing issues with devices on our estate as users were unable to install msix files due to security restrictions we placed on the estate, this msix file was still downloading as late as the 17th August 2024, all of a sudden today the file is now MSTeamsSetup.exe instead on https://statics.teams.cdn.office.net/production-windows/1.7.00.18901/MSTeamsSetup.exe, when was this changed and why have Microsoft decided to suddenly go against their guidance of installing teams via msix files as per their guidance on the bulk deployment site, I cant find any info on when this decision was made and why

Hello mattswan,

Good day. Thank you for posting in the community!

Microsoft changed the installation file for the MS Teams desktop app from MSTeams-x64.msix to MSTeamsSetup.exe. Unfortunately, there is no official documentation that indicates when this decision was made. This transition appears to be a response to ongoing compatibility issues that users faced with MSIX file installations, particularly in environments with stringent security restrictions that prevented users from installing MSIX files.

As a part of the community team, we are here to assist you in troubleshooting and providing information on the availability status of features. However, it's important to note that our community team and the Microsoft product development team operate independently. These decisions are made by the Microsoft product development team.

It might be beneficial to contact Microsoft support for finding the root cause why have Microsoft decided to suddenly go against their guidance of installing teams via msix files as per their guidance on the bulk deployment site. This could provide more detailed insights about the circumstance.

We recommend that you contact your Microsoft 365 administrator and follow the steps in this article https://learn.microsoft.com/en-us/microsoft-365/admin/get-help-support?view=o365-worldwide&tabs=online#online-support to create a support ticket to Microsoft.
