Download Only the Headers for Large Messages in Outlook
Here’s how to set up Outlook to automatically download only the subject, sender, and other minimal data for large messages that exceed a specified size:
Open Outlook Mail. Go to the Send/Receive tab. In the Send & Receive group, select Send/Receive Groups. Select Define Send/Receive Groups. In the Send/Receive Groups dialog box, choose the desired group. Select Edit. In the Send/Receive Settings dialog box, select a POP3 account from the Accounts list. Select the Include the selected account in this group check box. Under Folder Options, select the Inbox folder. Select Download complete item including attachments. Select the Download only headers for items larger than check box. Enter the desired threshold size. The default is set at 50KB. Repeat steps 9 through 12 for each folder that is set up to receive incoming email. Select OK.
Get the Rest of the Message
Now when you select Send/Receive, Outlook downloads only the header information for messages that exceed the threshold size. Getting the full emails is easy, as is deleting messages right at the server without downloading them in full.
