I have been using Office 2007 since Beta 1 and have had no real issues with the product (stability at the start, but that is much better in the final release). I have been using the RSS features which are really cool but just this morning Outlook is not updating my RSS feeds. On further investigations Tools|Account Settings|RSS Feeds no longer contains a list of RSS Feeds. I now have to delete each RSS and re-add it manually (I didn’t have an OPML file – doh!).
For those of you that are using Office 2007 and the RSS feed feature, I recommend using the Import and Export feature to create an OPML file of your feeds occasionally (then you wont loose them like I did).
If anyone else has experienced this issue then let me know and if I find a fix to this issue I will update this post.
