To set up Mac Mail to check your Office 365 email account follow these steps:
1. open Mac Mail as normal and from the Mail menu choose Accounts.
2. choose Exchange from the list. If you have an existing email account already configured, click the Plus button under the list of accounts to add your office 365 account.
3. Enter your name (first name and last name) and then department email address and then your SSO password (created at account activation, the one tied to your email account).
4. Click Sign In and wait while loading
Note: if you see the following dialogue box click the Next button
then enter the following details:
- email address: firstname.lastname@example.org (normal University email address)
- username: enter just your Single Sign On (SSO) in the format abcd1234 plus @OX.AC.UK (this address is case sensitive!)
- internal server address: https://outlook.office365.com (depending on which version of OS you're using, you may need to try the address with or without the https:// in front of it)
- external server address: leave blank.
5. click on Sign In
6. choose which features you want to sync. For example, if you want to bring over your contacts and synch Apple Calendar with your exchange calendar, select those options from the list in addition to email.
7. click Done to complete the set-up process.
To add your proper email address go to Mail/preferences/accounts/email address and drop down to edit email addresses, click on the plus sign (+) and add your proper sender address as email@example.com
Finally, when you compose a new email, the From address has a drop down menu where you can chose your proper address (eg firstname.lastname@example.org)
