When you subscribe to an RSS Feed, Outlook periodically checks for updated postings.
RSS Feed publishers can specify the maximum frequency at which a check for new postings should occur. For example, an RSS Feed might have a maximum polling frequency of 60 minutes — this means don't check for updates multiple times per hour.
After you add a Really Simple Syndication (RSS) Feed, you do not have to change any other settings.
However, if you want to customize your RSS Feeds, Microsoft Office Outlook 2007 offers several customization options.
The delivery mechanism for RSS content is known as an RSS Feed.
By saving RSS Feeds to an Outlook Data File (.pst) on your computer, your RSS Feed content doesn’t use your server space allotment.
When you use Windows Internet Explorer 7 or later and Microsoft Outlook 2010, you can view and maintain the same RSS Feeds subscriptions list in either program.
You do so by sharing one RSS Feeds subscription list via the Common Feed List in Microsoft Windows.
If you decide to keep RSS Feeds in an Outlook Data File (.pst) file, you'll only have access to those items on the computer where the file is located.
RSS Feeds that save items to a folder that is located within your Exchange mailbox are available from any computer that has Outlook and connects to your Exchange account.
