Thank you for the feedback. I just wanted to let you know that we have started work on bringing the ability to Copy to another folder. I will keep this posting updated to let you know once we have shipped this feature out to everyone.
Again, thanks for the feedback!evan-104 commented
don't see the option to "copy message to other folder" like before --- used to be one of the "move" choices
Thank you for your feedback.
We are investigating different ways to make accessing older emails easier for our users. We will report back when we have an update to this. Thank you for your patience!
