IOS outlook apps can't sign in O365 suddently
Hi John,
It can take up to 3-7 days after deleting the Outlook for iOS app on your mobile devices to clear the cache completely.
TechNet describes the following three options:
Option 1: Initiate a Remote Wipe for each user who has used the Outlook app for iOS and Android to connect to Office 365 or Exchange.
Option 2: Have all users delete the Outlook app. All data will be removed in approximately 3-7 days.
Option 3: Have each user remove their account from the Outlook app, and then delete the app from their mobile devices. To remove an account, have users follow these steps:
In the Outlook app, in Settings, tap Account Settings.
Tap Select an Account, and then, with the account selected, tap Remove Account.
Tap Device & Remote Data.
