Remove files from MS Outlook
I'm assuming you're using MS Outlook 2016. If so, the location of your data will be within your user's Library folder.

To view this:


Go to Finder
Press and hold the option key
Click on the Go menu and select the Library option
You can let go of the option key now
Within the Library folder navigate to the Group Containers folder
Within the Group Containers folder look for a folder starting with "UB" and ending with .office
Open this folder and you will see the Outlook folder


Within this folder are located any profiles you created - you can delete these as you wish.
