I am desperately missing one feature of Classic Mail in the new system. In the old system one could review attachments (pdf-files, Excel files etc, Scans) in the draft version in a final check before sending them out. The new system does not allow that anymore.
That is very problematic. Do you plan to fix this?
It was one of the reasons I kept using the classic version. As you are closing classic mail on Jan31,2019 this becomes urgent now.
I send it to myself first then if it's ok send to addressee you want to receive it.
