Prevent connection to Public Folders on Exchange?

I would like to avoid trying to connect to public folders in my Outlook 365 (Version 1809, Build 1082.80181 Click-to-run). I saw a way to do this in older setups, which involved creating a 0-valued HasPublicFolders key in the registry under "HKEY_CURRENT_USER\Software\Microsoft\Exchange\Setup". But it seems that this registry key is no longer around.

The autodiscover.xml that my outlook gets from the exchange server is trying to connect me to a public folder to which I don't have access, so I keep getting prompts for credentials to connect. I asked my IT team about it, and they just wanted me to make sure I didn't have an extra profile for that public folder (which I didn't). I've done repairs, uninstall/reinstall, etc., but the phantom public folder credential prompts keep coming back. Is there a way to tell outlook not to look for those folders? Worst case, I guess I could turn off autodiscover, edit that xml file to remove the reference to the public folder. Any other ideas?

Thanks!

Apologies: I meant to say that under my "Exchange Account Settings", I have "Cached Exchange Mode" checked, but have always unchecked the options for "Download shared folders" and "Download Public Folder Favorites"

As far as I know, you can't block PF in current versions. You can try adding the Setup key and adding that value to it - i tried it, but its not working. However, it might only work if you add the account after setting the key.
