Using Outlook for iOS for personal email and calendar management
I am also having the same problem since last Thursday the 14th. I have also done everything that was stated above by Alyssa8. I've cleared my cash, restarted my phone, done the airplane mode on/off, deleted and reinstalled the app, etc. I am only having issues with the outlook app, and can still access my emails fine in a browser. Please get back to me as soon as possible to address this issue.
