Install custom MS Teams background images

I do this a different way without the need of a script.
I just create a DMG using composer of the Teams background images in the required path location and just use Jamf's FEU & FUT package feature in policies to deploy straight in to each users account.

@garybidwell Thank you. I've never used that option. I will test that out for sure. Any "gotchas" with using FUE & FUT?

not really, its pretty simple to use as long as you remember it only works on DMG and not PKG. I like to set the permissions within Composer myself just as force of habit making PKG's all the time, but with the DMG FUE & FUT options it make it irrelevant as Jamf does all this automatically as part of the install process.
You just need to set your deployment frequency to "Once per user per computer" to ensure it deploys to every user account on every device.

How does JAMF know where to put the image for FUE/FUT? Microsoft kind of buried it in /Users/username/Library/Application Support/Microsoft/Teams/Backgrounds/Uploads? I could see doing that for a standard wallpaper, but I'm just not understanding how the FUE/FUT function works.

The path dropped into composer essentially becomes a static variable for everything after "/Library/Application Support/Microsoft/Teams/Backgrounds/Uploads". Everything before that is then a blank value that is just iteratively filled in when rolling through user account or language templates and permissions updated accordingly.

I copied your extact script but here this

Script result: /Library/Application Support/JAMF/tmp/Teams background: line 16: Support/Microsoft/Teams/Backgrounds/Uploads/: No such file or directory
/Library/Application Support/JAMF/tmp/Teams background: line 19: Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper: No such file or directory /Library/Application Support/JAMF/tmp/Teams background: line 22: Teams.app/Contents/Resources/icon.icns: No such file or directory Path is missing, creating required folders /Library/Application Support/JAMF/tmp/Teams background: line 28: : command not found mkdir: Support: Read-only file system cp: Support/Microsoft/Teams/Backgrounds/Uploads is not a directory chown: Support/Microsoft/Teams/Backgrounds/Uploads/*.*: No such file or directory

Hi All that script stopped working for us. Instead of repairing it, we moved to a package and use Jamf's FEU & FUT option. 

I followed below process and it worked for me-

- Uploaded Teams PNG file in /Private/Temp

- Drag that location to Jamf Composer

- Create PostInstall script as below -

#get current user
currentUser=$(/bin/ls -l /dev/console | /usr/bin/awk '{ print $3 }')

#Check if the images package was installed
sourceFiles=/private/tmp/Teams

#Check if Teams background & uploads folder exists
teamsPath=/Users/"$currentUser"/Library/Application\\ Support/Microsoft/Teams/Backgrounds/Uploads/

#jamfhelper path
jamfHelper=/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper

#set icon
#icon=/Applications/Microsoft Teams.app/Contents/Resources/icon.icns

if [ ! -d "$sourceFiles" ]; then
echo "Missing source files, script will fail, did not display messsage."
else
#Tell the user that the backgrounds are available.
"$jamfHelper" -windowType hud -windowPosition ul -title "Your title here" -heading "Microsoft Teams" -description "Check it out! New Teams video backgrounds are available now. We hope you enjoy them!" -icon "$icon" -button1 "OK" &
fi

#if teamsPath exists copy background images to the Uploads folder and set permissions, else quit
if [ -d "$teamsPath" ]; then
cp /private/tmp/Teams/*.* /Users/"$currentUser"/Library/Application\\ Support/Microsoft/Teams/Backgrounds/Uploads
chown "$currentUser":wheel /Users/"$currentUser"/Library/Application\\ Support/Microsoft/Teams/Backgrounds/Uploads/*.*
else
echo "Path is missing, creating required folders"
mkdir -p /Users/"$currentUser"/Library/Application\\ Support/Microsoft/Teams/Backgrounds/Uploads
cp /private/tmp/Teams/*.* /Users/"$currentUser"/Library/Application\\ Support/Microsoft/Teams/Backgrounds/Uploads
chown "$currentUser":wheel /Users/"$currentUser"/Library/Application\\ Support/Microsoft/Teams/Backgrounds/Uploads/*.*
fi

- Build as PKG

-Upload in Jamf and it works. No need of FEU and FTU

Hope it helps

I followed the same thing, however with the new teams client this needs to change a little here is my sample script 

#!/bin/bash

# Created by Brian LaMantia 6/1/2020
# Move FIS background images from /private/tmp to the current user's Uploads folder in Teams.
# Run after the images are deployed to the tmp folder then displays a message to the user.
# If the package fails, do not display a message.
# If you make this better, post a copy for me!

# get current user
currentUser=$(/bin/ls -l /dev/console | /usr/bin/awk '{ print $3 }')

# Check if the images package was installed
sourceFiles="/private/tmp/Teams backgrounds"

# Check if Teams uploads folder exists
teamsPath="/Users/$currentUser/Library/Containers/com.microsoft.teams2/Data/Library/Application Support/Microsoft/MSTeams/Backgrounds/Uploads"

# jamfhelper path
jamfHelper="/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper"

# set icon
# icon="/Applications/Microsoft Teams.app/Contents/Resources/icon.icns"

if [ ! -d "$sourceFiles" ]; then
echo "Missing source files, script will fail, did not display message."
else
# Tell the user that the backgrounds are available.
"$jamfHelper" -windowType hud -windowPosition ul -title "Teams Backgrounds Updated" -heading "Microsoft Teams" -description "Check it out! New Teams video backgrounds are available now. We hope you enjoy them!" -icon "$icon" -button1 "OK" &
fi

# If teamsPath exists, copy background images to the Uploads folder and set permissions, else quit
if [ -d "$teamsPath" ]; then
cp /private/tmp/Teams\\ backgrounds/*.* "$teamsPath"
chown "$currentUser":wheel "$teamsPath"/*.*
else
echo "Path is missing, creating required folders"
mkdir -p "$teamsPath"
cp /private/tmp/Teams\\ backgrounds/*.* "$teamsPath"
chown "$currentUser":wheel "$teamsPath"/*.*
fi

exit 0 ## Success
exit 1 ## Failure

Recently i have deployed teams background on macOS Sequoia and its working on both versions of teams like New Teams and Team Classic versions.

I have moved the images to following locations and set the permissions as suggested but it was not working for some reason. So i have directly uploaded all the images manually from teams app and noticed imaged are imported into following locations automatically (for one image two files will be added like thumb.jpeg and sourcefile.jpeg) and once required images are imported, i have drag and drop the "Uploads Folder" to composer and build the "DMG with FUT & FEU" for the deployment.

New Teams: "/Users/<username>/Library/Containers/com.microsoft.teams2/Data/Library/Application Support/Microsoft/MSTeams/Backgrounds/Uploads"

Teams Classic Teams Version: "/Users/<username>/Library/Application Support/Microsoft/Teams/Backgrounds/Uploads"
