Add a Microsoft Office 365 Calendar

Follow one of the following two procedures. They work for me:

Autodiscovery: (currently not working)

1. Select the autodiscovery checkbox.
2. Enter as the mailboxname: <username>@<mycompany>.onmicrosoft.com
3. Enter as the username: <username>@<mycompany>.onmicrosoft.com
4. Press the “Perform autodiscovery” button and when the URL select box pops up select the right server.

Manual entry: (tested last on may 3rd 2013)

1. Log on to the webmail for your Microsoft Office 365 account.
2. Click on the little settings wheel in the upper right corner direct after your name.
3. Click on “options”.
4. On the “account” page click on the “Settings for POP or IMAP access…” link. A new window should pop up.
5. You will see three settings (pop, imap and smtp) and for all three the “Server name:” field is the same. Probably “outlook.office365.com”
6. In Lightning create a new calendar and fill in the fields as follow:
7. Server URL: https://<server>/ews/exchange.asmx  (replace <server> with what you found in step 5)
8. Mailboxname: <username>@<mycompany>.onmicrosoft.com
9. Username: <username>@<mycompany>.onmicrosoft.com
10. DomainName: <leave empty>
11. Click the “check….” button. When it asks your password and username fill in the password and check the remember checkbox.
12. Select as Folder base “Calendar folder” and for the path below base “/”.

Finish the create dialog.
