The N8 comes with Nokia's Mail for Exchange software built in, providing push-based bi-directional synchronisation of mail, contacts, calendar and notes information with Microsoft Exchange 2003 SP2 or later.
The N8 also supports multiple concurrent Exchange email accounts.

Select Start:

Enter in your Exchange email address and your Active Directory password, the same password you use to log into your office PC. Select Next:

Select Mail for Exchange as the type of email account and then Next:

Add your username and domain. Again the username will be the same as that used to log into your office PC. If you do not know the domain information, contact your IT department, but it will be the same as that contained in the "Log Into" field on your PC when you log in, beneath the username and password fields. Select Next:

The client will then attempt to determine the details of the Exchange server from the email address, if it is unable to determine the information automatically, you will be prompted to enter in the name of the mail server:

Enter in the name of the server, again if you don't know this information you should contact your IT department, but if you access your email via a web browser it will be the same address as this, normally in the form "mail.company.com"

If the Exchange server uses a self-signed, or non root-trusted certificate, you will be warned:

Select Options:

Select the option to Accept Permanently to avoid having to confirm the certificate warning on each connection, you will be prompted to confirm this selection:

Select Yes, then enter the name of the Exchange server.
