Below are the steps you need to follow to Manually Configure message download preferences in Outlook: 2013:
- On the Send/Receive tab, in the Preferences group, click Download Preferences.
- Click one of the following options:
- Download Full Items: This is the default setting. All messages and attachments are downloaded.
- Download Headers and Then Full Items: After message headers are downloaded, downloading of message bodies and attachments begins. When downloading a large amount of items, this setting is useful so you can see message headers quickly and then choose a message to open without first waiting for all messages to be downloaded in their entirety.
- Download Headers: No message bodies or attachments are downloaded. This reduces the data transfer amount and connection time. When you open an item, the full item is then downloaded from the mail server.
- Slow Connections Download Headers Only: When a slow connection is detected, message bodies and attachments are not downloaded. If this option is not selected, the three previous choices determine what is downloaded regardless of the connection speed.
- In addition to Exchange folders, Cached Exchange Mode works with shared folders. Examples of shared folders include another person\’s Exchange folders when you are using Delegate Access, or SharePoint folders.

- On the E-mail tab, click the Exchange account, and then click Change.
