用户RSS功能异常：Outlook报0x800C0008、IE提示下载中断求助

Based on the symptoms you described—isolated to a single user on the device, failures in both Outlook (error 0x800C0008) and Internet Explorer, and no issues with a local test RSS feed—the problem is almost certainly tied to user-specific profile data, settings, or cache corruption. Here are targeted steps to resolve this:

1. Clear Outlook's RSS Feed Cache #

Outlook stores cached RSS data that can become corrupted over time. Let's reset this:

• Close Outlook completely (check Task Manager to ensure no OUTLOOK.EXE processes are running).
• Navigate to the user's RSS cache folder: %USERPROFILE%\AppData\Local\Microsoft\Outlook\RSS Feeds
• Delete all files in this directory (they'll automatically rebuild when Outlook restarts).
• Next, locate the RSS database file: %USERPROFILE%\AppData\Local\Microsoft\Outlook\Store\RSSStore.dat (path may vary slightly by Outlook version). Rename it to RSSStore.dat.old to force a fresh database creation.
• Restart Outlook and attempt to subscribe to an RSS feed again.

2. Reset Internet Explorer's RSS Configuration #

Outlook relies on IE's underlying RSS engine, so resetting IE's RSS settings often fixes cross-application issues:

• Open Internet Explorer as the affected user.
• Go to Tools > Internet Options (or click the gear icon > Internet Options).
• Switch to the Content tab, then click Settings under the Feeds and Web Slices section.
• In the Feeds Settings window, click Reset to restore default RSS configurations.
• Clear IE's temporary files: Go to the General tab, click Delete under Browsing History, check Temporary Internet Files and Cookies, then click Delete.
• Close IE and test accessing an RSS feed URL directly again.

3. Check User-Specific Registry or Group Policy Settings #

It's possible a user-specific policy or registry tweak is blocking RSS functionality:

• Open Registry Editor (regedit.exe) as the affected user.
• Navigate to HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Feeds
• Compare the values here with those from a working user on the same device. Look for flags like DisableFeeds set to 1 or restricted feed URL lists.
• If you find non-default entries, reset them to match the working user's setup, or delete the entire Feeds key (it will be recreated when IE/Outlook launches).
• For Group Policy: Run gpedit.msc as the user, navigate to User Configuration > Administrative Templates > Windows Components > RSS Feeds, and ensure no policies are enabled that block RSS feeds.

4. Repair or Recreate the User's Outlook Profile #

A corrupted Outlook profile can cause unexpected RSS failures:

• Open Outlook as the affected user.
• Go to File > Account Settings > Account Settings.
• Select the user's email account, click Repair, and follow the wizard to fix profile issues.
• If repair doesn't work, create a new profile: Go to Control Panel > Mail > Show Profiles, add a new profile, set it as the default, and test RSS feeds in the new profile. If it works, migrate data from the old profile to the new one.

5. Rule Out User-Specific Security Software Restrictions #

In rare cases, antivirus/firewall software may apply user-specific rules blocking RSS access:

• Temporarily disable the security software for the affected user (with appropriate caution) and test RSS functionality.
• If the issue resolves, adjust the security rules to allow Outlook and IE to access RSS feeds.

Since other users on the same device work fine, focusing on user-specific data and settings should resolve the problem.
