URLs for the latest production build of Microsoft Teams were updated yesterday, but the date there is 3 weeks ago

Hi
Thank you for this project.

I manually check https://github.com/ItzLevvie/MicrosoftTeams-msinternal/blob/master/defconfig if I need a link to the latest version.
Today I noticed, that URLs for the latest production build of Microsoft Teams were updated yesterday, but the date there is 3 weeks ago (October 12). https://github.com/ItzLevvie/MicrosoftTeams-msinternal/blame/master/defconfig
Does it mean that the date is wrong?

Latest production builds are out of date in defconfig

E.g.:

https://teams.microsoft.com/desktopclient/installer/windows/x64?ring=general returns https://statics.teams.cdn.office.net/production-windows-x64/1.4.00.8872/Teams_windows_x64.exe

However, defconfig lists:
1.4.00.7174 (win-x64) - published to CDN on Friday, March 12, 2021 at 3:39 PM with 104 MB: https://statics.teams.cdn.office.net/production-windows-x64/1.4.00.7174/Teams_windows_x64.exe

Just a question....difference between defconfig and defconfig2?

I noticed that defconfig has newer electron builds and defconfig2 has a bit older electron builds but also new teams in it....why not just make 1 list?

Host sharing Desktop can't click own mouse when other person is controlling

When you share a desktop and give someone control of your desktop, you loose the ability to click your mouse, it works very sporadically, meaning you need to click 20 times before it actually clicks on something. You even can't take away the control rights, starts working fine when the other person releases control of your desktop.
This happens on all MS Teams builds, still not fixed.

How to read the 2.0 and 2.1 version number

Hi!
I tried to figure it out, but couldn't really. I can't find a pattern on my own, so I am asking:
For example this 2.1 version: 23095.300.1995.3049 <- how does one read that?

MS Teams v1.5 on Linux ?

Hello,

Would it be possible to get MS Teams v1.5 on Linux ?

Thanks !

Thank you for doing this! ❤

Thank you for creating this repo with the urls.

It helped me to update teams. 😅

macOS: headphone microphone not working after waking macOS

After waking macOS from screensaver or sleep, Teams is unable to pick up the headphone microphone (e.g. Plantronics C3220 USB-C). Only "New" Teams is affected, all other apps and the OS pickup sound from the headphone microphone, but New Teams is silent. Old Teams is unaffected by this bug. Restarting Teams fixes the problem but it's very annoying.

Webhooks not displaying new lines correctly in Windows clients

Looks like it has something to do with how the windows client is interperetting "/n" or '
'

More details and confirmation: https://answers.microsoft.com/en-us/msteams/forum/all/incoming-webhook-messages-not-displaying-in-latest/f42a0466-8a63-4523-a4c2-ee3d8463a0e3

MacOS-Arm64 - Videos Not Showing - Must Pin Videos to see them

Dropping this here as it was noted here by multiple users:

https://techcommunity.microsoft.com/t5/microsoft-teams-blog/announcing-microsoft-teams-optimized-for-apple-silicon/bc-p/3604649#M10970

• When running latest arm 64 builds the video preview does not show
• Have to “pin” video (host and attendees) to be able to see their video feeds
• Can consider video functionality broken
• Reproduced on Apple MacBook Pro M1
• Reported on M2 systems in thread above

Use GitHub Actions

You can use GitHub Actions to automatically update and commit the defconfig and defconfig2 files periodically instead of updating and committing it manually.

Android APK Versions

Hi, just wondering if there is the same kind of access for APKs as there is for Windows / MacOS installation files.

GCC/GCCH/DOD Builds?

MicrosoftTeams-msinternal/defconfig

Line 30 in 22068b0

URLs for the latest production build of Microsoft Teams:

This link doesn't appear to have the downloads provided for GCCH.

https://statics.teams.microsoft.com/production-osx/1.5.00.4683/Teams_osx.pkg
https://statics.teams.microsoft.com/production-windows-x64/1.4.00.32771/Teams_windows_x64.exe

Both URLs sourced from https://gov.teams.microsoft.us/download

I'm a GCCH user so not sure what the DOD/GCC build links are.

Feature Request - Publish a homebrew cask

Feature Request: Homebrew package

Could you create a homebrew cask and publish this, so that MSTeams can then be updated using the standard brew update command, rather than having to check every few days about new Teams updates.

Maybe have 4 different packages
production build: microsoft-teams-production
preview build: microsoft-teams-preview
exploration build: microsoft-teams-explore
continuous development build: microsoft-teams-dev

Thanks..

Would it be possible to include the same for the VDI client MSI installers for teams as well?

Teams Add-In for outlook not working with latest installation

With the installation of version: 23104.900.2020.2949
I no longer have the Teams add-in working in my Outlook installation.
The add-in shows in my installed add-ins, but all traces of functionality are gone from outlook[desktop]. I haven't checked with web.

Markdown broken in Mac edition

Markdown support on Mac edition is not functioning, and have had problems for quite some time.

If I want to type “`” and then a monospace command and then “`”, then it does not show as monospaced but as “`monospace`”.

But I can make Monospaced characters in the Paragraph menu, but it cannot format a paragraph as monospaced. This is totally reverse logic.

So typing ``` and then space, usually would allow me to type monospaced paragraphs, but not on Mac.

On Windows all of these seems to work. And as they are documented.

Also in the latest version of Teams, Paragraph menu has been moved to a submenu, but submenu does not even show it has submenus.

I hope these inconsistencies in the Mac version can be fixed, thank you!

Remove blank lines defconfig2 between non-msix and msix builds

Would it be possible to remove the blanks lines between the non-msix and msix builds ? I wrote a regex to capture the version and urls and with that blank line in between it makes it darn impossible.

macOS: WHERE are the login accounts / UPNs cached?

I spent a couple of hours trying to figure this out and eventually gave up.

When I launch Teams.app (currently using beta 1.6.00.10052 on macOS 13.3.1) I am greeted with a login/auth popup containing 7 accounts. I only currently use 2 of them. The others are related to test accounts that I used at some point in the distant past.

How can I clear this cache or remove these accounts from the chooser? I've traced every file that Teams seems to touch from launch leading up to that window appearing using eslogger. I also traced the HTTP traffic with Proxyman. I still can't figure out where in God's name this data is coming from.

Please help!
