Silently removing WebEx Productivity Tools

I'm looking for a good method to remove WebEx Productivity tools, preferably silently. So far, all I am finding is Cisco's page to have the user run the uninstaller.

https://help.webex.com/en-us/WBX32304/How-Do-I-Uninstall-Webex-Productivity-Tools

The reason for this removal is those tools will be blocked in May 2021 for macs: https://support.microsoft.com/en-us/office/outlook-for-mac-%e2%80%93-planned-update-for-injection-based-plugins-dc6f9490-da7d-4d35-8793-835636b954d5?ui=en-US&rs=en-US&ad=US

I don't have any experience with installing or uninstalling WebEx, but for other applications that I've wanted to silently uninstall on my fleet, I've successfully been able to build (or rebuild) the installer package/dmg, make sure that I've indexed the package/dmg in Jamf Admin, which then allows Jamf Pro to silently uninstall the software via a policy. Obviously, you'd need to test this and if your software has already been deployed/installed (which is sounds like), this process may not work...so YMMV. But it's the route I'd go -- basically use Jamf Admin to index the WebEx installer which then enables the uninstall option in Jamf Pro.

One thing that's not clear -- I'm almost certain that this uninstaller functionality relies on a package receipt being installed on a system. But if WebEx was installed prior to all of this, then the package receipt won't be understood or parsed by the jamf binary that's doing the uninstall work. So you might have to jump through some hoops like: 1) index the WebEx installer to create the uninstall option (or, even repackage the WebEx installer using Composer) 2) re-install WebEx silently on all your client machines so that the package receipt exists 3) then use a jamf policy to execute the uninstall command.

Yeah, a lot of work and hoop-jumping, but it's a route I'd explore were I in your shoes. Google's not showing me any Mac tools for (natively) silently uninstalling WebEx (I suspect that it doesn't exist).

@thefishyfew If the Webex Productivity Tools are installed there should be a folder with that name in /Applications which contains an uninstaller. You can call that directly, say via an Excute Command line in a Files & Processes payload, with this: "/Applications/Webex Productivity Tools/Uninstall.app/Contents/MacOS/Uninstall"

@damienbarrett I can't speak for removing the Cisco WebEx Meetings app itself. Given how non-silent the install is I doubt the un-install would be any better. BTW, when you do try uninstalling it don't forget the remove the Library/Application Support/WebEx Folder from each user's home directory. It appears that every time a Cisco Webex app (Meetings, Meeting Center, Training) updates it leaves a copy in that folder.

That's good to know that there's a silent uninstall option for Webex. I couldn't find any documentation for this when I was Googling (but perhaps my GoogleFu was just off).

Provided there's a silent uninstaller that can be triggered with a policy, it should be very simple then to also write a bash script that can delete any leftover files and settings, and even Apps themselves. Thanks.

It's not completely silent but I think it's good enough. Also I highly recommend indicating spaces very specifically when executing a command in Files and Processes.

/Applications/Webex Productivity Tools/Uninstall.app/Contents/MacOS/Uninstall

@darthmaverick @damienbarrett I have a payload-free package for removing Webex Productivity Tools at https://office-reset.com/macadmins/ ....this invokes the native Uninstall routine, then cleans up the parts that are left behind.

@pbowden you continue to be the :goat:. Thank you for that amazing resource!

I wrote this for our internal use but it was vetted by the Webex PT team so customers could use it as well. Does not handle closing Outlook so it is silent but a restart of Outlook is required to fully complete the removal.

has anyone figured out the WebEx scheduler? I want to see about deploying this. I believe it's just O365 Tenant driven

@wmateo That is correct. Configured in your tenant
