Droid 4 syncing corp email with Exchange Active Sync using the native email client. I receive emails with txt attachments from my nightly server backups(Backup Exec). When i open the email on the Droid, the txt attachment shows unsupported file type...BUT...if i take the same email in Outlook and forward to myself then the phone will open the txt attachment with Quick Office. I also tried forwarding the email to myself from the phone but the attachment still shows unsupported file type..The txt file is only about 20kb so it isnt a size problem..
