Motorola Razr M, Android version 4.1.2.
Using the Email app that came with phone, Roadrunner Email, have used both Auto Detect and Manual to enter email settings. However, whenever I "Reply All" within email, the message gets caught in the Outbox and hangs. Troubleshooting - I have already: Deleted and reinstalled the Email Account a half-dozen times; I have restarted phone, turned off and back on, etc... This only occurs with "Reply All", "Reply" works fine.
