Clearing Apple Mail cache on IOS mobile devices for migrated accounts

In some cases after an email migration, your phone or mobile device may hold onto some cached information that makes it difficult to transition to a new Microsoft 365 account. 

These instructions are for iPhone and iPad users that have the Apple Mail app. If you use the Microsoft Outlook app, refer to the specific instructions here: Clearing Outlook app cache on IOS or Android devices

If Apple Mail still redirects you to an old account we may need to reset your Authenticator settings - please contact the VetEvolve IT
