Attensa for Outlook is optimized for performance. There is no impact from RSS subscriptions. Attensa for Outlook stores RSS subscriptions and articles in a separate file outside of Outlook. Your users get a uniform view of their email and RSS content (including the option of reading articles offline). They will not experience performance or storage issues related to the additional content.
