My Mail will not open
My mail will not open - I see I have a mail (1) but when I ask it to open, I am getting just the outbox window, not the full Mail
iMac 21.5″ 4K, macOS 12.3
Press and hold a Shift key while launching the Mail app again. That will launch the Mail app in windowed mode (not full screen) with no message selected.
If that does not resolve the problem, please refer to If you can’t open Mail on your Mac - Apple Support.
