I have found that the outlook on my system has stopped updating the RSS Feeds from the Microsoft forums OK - Just to confuse the situation, it is still doing a couple of the feeds.
The only change to the setup - Basic win-10-Home, and Family 365
since it was working as wanted are: updates installed by Microsoft, and I went into "Accounts" "Accounts" and moved the top id entry down, so that instead of the Virginmedia.co.uk account, my gmail.com account was the default !
OK, I did setup the Outlook under an @virginmedia account, and was logged in using that when I added the RSS feeds, but should that matter with feeds from microsoft forums such as
"Outlook Blog articles"
And while entering this I also note that most of the feeds entries are not showing a folder, So I have changed the one to use a new folder in the .pst file, well, maybe that will gat a new post
