Big Sur Email Problem
Upgraded to Big Sur. Mail All Trash has disappeared. In fact most of the "All" folders are not installed. My email sidebar is not sorted into an "All" section and an "On My Mac" section. The sorted "All" folders exist on my Time Machine. Specifically, the All Trash exists on my Time Machine with two subfolders: "freds101" and "On My Mac". The lost emails exist in "freds101", but there is no "freds101" in my sidebar. When I delete an email it does not show up in Trash (probably goes to "freds101 folder, wherever that is). In the "Accounts" section, my email is set that deleted emails go to Trash and that Trash is never emptied. Please help me get Mail functioning normally.
