Your Office 365 email is held in a Microsoft Exchange mailbox and it is a straightforward process to add an account to any device using autodiscover. The only information you should need is your email address and the password for your account.
The exact process will vary according to the device but in general, you need to:
- Find out where to manage mail accounts and choose the option to add a new account
- Choose 'Microsoft Exchange' or 'Office 365' as the account type.
- Enter your email address and password
- The device should now find the details for your account
- Finish the process by adding any additional information, such as name for the account.
If you are asked to re-enter the password at any point, e.g. with Microsoft Outlook, do that and tick the box that asks to save the password.
