need to create an auto-label policy for all sharepoint and onedrive

Jason_B1025 I believe in the future, there will be a Private Preview for an "all" option. From my understanding, they are going to get this more looking like a DLP policy where you have the option to just select "all." Because, to your point, it is unrealistic to expect an admin to type in thousands of URLs to include every SP site and/or every OD URL in their org. My company has over 85,000 employees, so we kinda laughed at the notion that we would have to type in every single one of those. You may contact and confirm this roadmap item with someone from Microsoft, but as I say, that is our understanding based on some recent meetings. For the time being, they'll suggest you look at your Content Explorer in the Compliance Center to see where your most sensitive sites are (aka the ones that house the most sensitive information or whatever) and just add those URLs. Sort of taking care of the biggest fish within the fewest amount of URLs.
