Office 365 (Apple Mail / Calendar) - Configure Apple Mail / Calendar on Mac OS 10.9

Best Effort Support Only

This document contains instructions on using a non-Microsoft email client, such as Apple Mail or Thunderbird. Microsoft does not recommend these clients for use with Office 365, and there are often significant limitations in client functionality as a result.

Because of this, the DoIT Help Desk is only able to offer best effort support for these clients, and certain issues may require the use of a Microsoft client in order to be resolved. For more information on Office 365 client support, please see: Office 365 - Which clients/protocols will be supported?.

This document explains how to connect to the Office 365 service.

  9. One final step is required for Apple Mail users: disable client side spam filtering. After starting Apple Mail, it is very important that you disable this feature before using Apple Mail.

Note: If your original WiscMail/WiscMail Plus account was configured on this device, use the following instructions to remove the account: Apple Mail / Calendar - Removing an account.

Important: Depending on the size and amount of emails you have in your account, Apple Mail may require some time to completely download all of your mail (and other data) the first time you load Apple Mail after configuring your account.

Configure Access to the Campus Directory (Whitepages)

Remember: the Global Address List (GAL) will only contain Office 365 accounts. Therefore, you may still need access to the Campus Directory (Whitepages) to find the person you are searching for.

Use these instructions to configure the Campus Directory (Whitepages) within this client.
