Unable to delete messages from MS Office 365/BT Connect account

[grahamhills]

I can't delete messages from my (MS Office 365) BT Connect account - when I try I receive a message saying "access denied - the entire error report is listed below" The list below just says access denied.

I appear to be able to send messages and forward them but can't get rid of them - quite bizarre.

Anyone know what's going on here?

My BT email appears to be working, yes, but I still can't delete or move emails on Outlook Web App. I am not convinced that the "Access Denied" error has anything at all to do with the recent Service Status troubles.
