If you can reliably reproduce the issue, open a support case so it gets properly investigated and fixed. In the meantime, you can try making the change via PowerShell as a workaround.

@Vasil Michevsorry.. can you please share the link where I can properly share the concern? Thank You

I'm moving this conversation to the Security, Privacy & Compliance space which I believe is a better fit for this content.

I am having exactly the same error when trying to edit an existing DLP policy.  I tried both IE11 and Chrome with the same result.  Sometimes (but not always), if I refresh the screen, the change I made before clicking save will actually have been made.


Note to Microsoft:  STOP trying to invent new navigation and edit widgets in admin tools.  I haven't got time to be your lab rat - I have real work to do and I just need the admin tools to work!!

The correct place to report this is via a support ticket, or by using the Feedback functionality in the SCC. And in the meantime use PowerShell instead to make the changes to the policy.

@JeffV I'm getting the same thing in trying to create a new (first) DLP policy in our system. I'm wondering if it's a licensing issue..
