We setup a Retention Policy on all sites under the Information Governance section of the M365 Compliance center. It locked all sites from deletion and won't let users delete folders with files in them.
We turned this off last week and it still won't let us delete anything. How long does it take to get rid of the retention policy and unlock site deletion?
EDIT Do NOT Enable Retention in Compliance center. It is a can of worms that will cost you time and money. MS has a huge bug they are failing to address right now that is costing our organization tens of thousands of dollars and they will not escalate the ticket beyond simple support tier.
