Renew Exchange Account
We have added some new enhancements to Exchange and Office365 support, including calendar and contact sync.
For these to work well, you may need to remove and re-add your account as Exchange ActiveSync.
To remove your account, please tap More… | Various Account Settings | Select the account you would like to remove | Edit Account and then Remove Account.
When re-adding the account as ActiveSync please select Add Other Account | Exchange | ensure the ActiveSync checkbox is enabled and continue to add your account.
