Thanks, Emily. Regarding Feedback, there's a thread like this regarding a message Outlook sometimes spits out, something like "Operation cannot be performed because the object has changed". Neither the offending operation nor object nor object change is identified.
This morning I clicked "send" on an email that had been sitting open all night. I got that message, as I do occasionally.
It presents under a variety of circumstances, e.g., if you try to move something from one folder to another. The thread started I think more than 5 years ago. Plenty of seemingly knowledgeable people have commented on possible causes. Some sound quite plausible.
In all that time, no one identifying as being with Microsoft has said boo. Feedback, even constructive feedback, goes entirely ignored. Microsoft's aloofness is irritating.
No need to answer. It might get you in hot water.
