Built in profile maintenance (shrink etc) in the Azure portal, should simply need to target the relevant share and attach a schedule
SteveDMSFT Ideally this should be included in the solution - FSLogix/Invoke-FslShrinkDisk: This script will shrink a FSLogix Disk to its minimum possible size (github.com)
Either allowing to be run on a schedule against a particular share or run automatically against a profile after the disk is unmounted.
