It's the last time the user accessed a specific feature, such as email, calendar, groups, etc. But it gets updated once a week, or even slower... I'll remind the Microsoft folks to publish more details on this.
Hey Vasil, Thank you very much for your reply. I have even checked your blog post regarding these attributes but did not find enough information. I would appreciate if you could request Microsoft to update us with adequate details. Appreciate your assistance and Thank you.
I recently played with those attributes and published in a blog. But it seems Microsoft has removed most of these attributes. There is no document when those attributes are introduced, and there no notification when those attributes are removed. Do you know the reason for these attributes removal?
