Using Outlook for Android in business environments for email and scheduling
Microsoft outlook rutrenly forces users to re input passwords for IMAP account and non Microsoft accounts such as gmail and yahoo, bot not Outlook or Hotmail accountd especially after upgrades. This is intentional and NOT a program error ! This is industry contemp for competors and NON Microsoft environments that you wont find with Google apps. Just like Microsoft forces apps and programs to Microsoft perfered defaults after upgrading. They will not stop these practices and ruteenly makr elaborate excuses and reinstall based fixes. If you have an Android phone use the gmail app. This will require 2 separate apps. One for MS based mail and one for your others. Quicken app for Android often request repeat password input , they are to lazy to write a finger print login option or tablet friendly scrolling and fonts. Microsoft is their own worst enemy...
