How to remove Office 365 completely

Hi Macgeek, I would not use composer to package a script. Jamf has a script section so use Jamf to handle it since it runs as root anyways. Here is my MS Office uninstaller script:

#!/bin/bash

consoleuser=$(ls -l /dev/console | awk '{ print $3 }')

echo "logged in user is" $consoleuser

echo "Kill Microsoft Office Process..."
pkill -f Microsoft

folders=(
"/Applications/Microsoft Excel.app"
"/Applications/Microsoft OneNote.app"
"/Applications/Microsoft Outlook.app"
"/Applications/Microsoft PowerPoint.app"
"/Applications/Microsoft Word.app"
"/Applications/Microsoft Teams.app"

I'm confused as  to why you are using composer to install a script? Any script can run direct from within a policy. I use this one, to remove Office files. It does not remove Teams, I've not ammened it, but other than that it does a good job. The creators name is in the script.

#!/bin/bash

if [[ $EUID -ne 0 ]]; then
echo -e "
ROOT PRIVILEDGES NEEDED!
You have to run this script as root.

exit 1
else
echo -e "

You may need to reinstall Microsoft Silverlight.
You can now remove icons from Dock (if any!).

Take a look at this webpage:

https://office-reset.com/macadmins/

There is a package for a complete removal of Office. This site is run by Paul Bowden from Microsoft. His tools are top notch. 

Refer to this official article provided by Microsoft Office: https://support.microsoft.com/en-us/office/uninstall-office-from-a-pc-9dd49b83-264a-477a-8fcc-2fdf5dbf61d8

Echoing what @Tribruin says - the Office Reset packages work great.

Thanks Tribruin,

The removal script on that website does a good job and is very fast. However, it still doesn't completely remove/change all of Microsoft Office. When I install our regualar version of MS Office and Word is launched you see places that allow you to sign in. If you try to sign in you only get a blank page.

When I install Office 365 and login to register my ID I don't get the same results. I remove Office 365, reinstall our regular version with our serial number and at first launch I'm presented with a sign in button. If I try to sign in I am able to. 

In Windows we are allowed to change that correctly so the user cannot log in after 365 is removed and our version with the serial number is installed. It appears that can only be done correctly using Windows.

I tried this using the instrustions for Jamf Pro but it didn't work.  seemed straight forward.  I set it for the login trigger but no dice.
