Additional RSS feeds appear in Outlook after a user signs in to Microsoft 365 on a new computer

Problem

Consider the following scenario. When a user signs in to Microsoft 365 on a new computer, the user's RSS feeds are transferred to the new computer. Additionally, the RSS feeds that are already on the new computer are also added to the user's account. If a second user signs in to Microsoft 365 on the new computer, the second user's RSS feeds are added to the new computer. Additionally, all the RSS feeds that are available on the new computer are added to the second user's account. This includes the RSS feeds of the first user. In this scenario, the following issues may occur:

• If you obtain a secure RSS feed when you log on to a computer, you may be prompted for your credentials every time that you use the account.
• The RSS feeds may contain personal data.

Cause

Windows Internet Explorer uses the common feeds list to check RSS feeds. A separate list for Microsoft Outlook is included so that the RSS feeds are displayed in Outlook instead of in Internet Explorer or vice versa. Outlook saves the RSS feeds to your Microsoft Exchange Online account. If you have multiple accounts on multiple computers, the RSS feeds propagate from one account to another.
