Changing "retention type" on an existing retention label in MS Purview

Hi K-dub,

Thanks for the question! Here is a link to the documentation about modifying existing labels: Create retention labels for exceptions - Microsoft Purview (compliance) | Microsoft Learn

"Most settings can't be changed after the label is created and saved, which include:

• The retention label name and the retention settings except the retention period. However, you can't change the retention period when the retention period is based on when items were labeled."

So, you can change the retention period for a label, but nothing else. If you'd like to change the other settings, the best process is to create a new label and use PowerShell to replace it 1:1 with the old label.

Please let us know if you have other questions.

Thanks!
