Here is what happens:
When I open any application within Office 365 (Word, PPT, The new Office Android app, Excel,...etc.), I come across files that I haven't touched for years to be shown as (you frequently open this).
No matter how many times I remove these files from the Recent page, they show up again with the same label (You frequently open this).
This is quite annoying as it takes space away from the files that I really need to be in the Recent page or even the files that I actually open frequently.
Secondly, it makes me wonder if there is anyone with access to my files! although I have taken measures to make sure that these mislabeled files are not shared with anyone.
