My organization just switched to the Droid Razr Maxx, one of the phones is having an issue with adding a corporate sync email account. Whenever we try to add the account it says that it can't add because of duplicate account "Null". I don't see this "Null" account anywhere, so i can't seem to remove it. I'm not really sure what we can do, besides doing a reset and would only do that as a last course of action. We are running android version 4 and using office 365 exchange.

Try clearing Cache and Data for the following apps under Settings -> Apps -> All (tap on each app and then tap Clear data and Clear cache buttons where available):

  • Email
  • Exchange Services
  • Google Account Manager

This should clear all the accounts (including the GMail one), and should allow you to add the Corporate account.
