I am using the Outlook 365 app for Android on a Samsung Galaxy 3 s for a work email account. It was working fine until yesterday, when it got stuck in offline mode and won't go back to online mode despite data and Wife connections. Any suggestions would be appreciated. The Outlook 365 app is working fine on my desktop and on my laptop. The problem appears to be isolated to the phone. Thank you. -- Keri L. Heitner, PhD . All Aspects Research .
