OV9

When I try to delete individually or in multiples I get this message: The submitted form was invalid. Try submitting again.

I get the same.

Never tried to, but just experimented there and got “this message was successfully deleted” (or similar)

It's a GCHQ request I had to put in place for certain individuals.

I will take no further questions on this subject.

All your PMs are belong to us.

Works for me - must only be an elite subscribers feature.

Ah, if I go into the message in question and delete it from there it works.

If I try and select the messages in the inbox and use the delete option from the drop down menu then it doesn't work, as per above.
