So, to get full control, it is necessary to uncheck the “Use publisher’s recommendation” box, AND to create a custom Send & Receive group (or modify the settings of the default group). So, create a new Send & Receive group and in its properties, select the RSS feeds that you want to update at the higher rate.To do this, go to the File tab, click Options in the left column (its below Help), select Advanced in the Outlook Options dialog, and scroll down to Send and receive. The screen shot above shows a sample RSS feed being prepared for updates every minute.
I've had a miserable experience with RSS feeds in Outlook, especially with my feeds from the Trilogy sites.
By creating a send/receive group for RSS feeds, you can still update your RSS feeds when you have time to read them.
You can configure the Send/Receive behavior for your RSS feeds in a similar fashion as for your mail account.
Also, it seems that Outlook’s send/receive process is getting slower because of the amount of RSS feeds that I have.
As my mail is my main priority, is there a way to configure Outlook in such a way that it will only download RSS feeds when I want to?
