Write-up for issue #77, and index it A Microsoft 365 mailbox could only ever collect mail from Inbox. Covers why it was never a regression (Graph accepts seven well-known folder names in a path and treats everything else as an identifier, so reading a folder BY NAME had never worked), why the screen contradicted itself (the move-to field had the resolver and a Verify button, the read-from field had neither), what changed, and what remains unproven -- a successful nested match, and the app-only combination. Adds the row to Bugs-Resolved and the sidebar entry.
