Mail, RSS feeds, settings for target folder are lost, Outlook 2013, Windows 8

Hi :)

I am using Outlook 2013 on Windows 8 (on one computer I am administrator, on second using user account).

On both computers I've changed in Mail Setup, RSS Feeds destination folder for RSS feeds to go into local folders into local.PST.

When I exit from Mail Setup and return all settings for RSS destination folder are reverted and RSS feeds are directed to go into folder onto Exchange server. Still worse, after each run of Outlook on Exchange server in RSS folder are created new one folder i.e (Technet blogs on first Outlook run, Technet blogs (1) on second Outlook run... etc.)

Any suggestion ?

Best regards
