Opens .msg files flawlessly while the Android Outlook app cannot.

★★★★★ Garry Cooper · Feb 21, 2024

New phone and couldn't open winmail.dat files. The frustration stopped when I downloaded Letter Opener. Worked perfectly.

★☆☆☆☆ St Marks Regents Park · Mar 28, 2024

Useless. It froze everything irretrievably.

★☆☆☆☆ Tony Wilcox · May 10, 2025

Didn't open the screenshot that it was installed for

★☆☆☆☆ Len Keck · Oct 6, 2024

Can't decipher Outlook calendar invitations

★☆☆☆☆ Shaun Phillips · Jul 20, 2025

Can't shrink the email to view without scrolling. The scrolling locks out too. Not good at all.

★☆☆☆☆ Trevor Fox · Apr 27, 2025

It's rubbish it doesn't give me the information I'm looking for.
