Using New Outlook on Windows for professional communication and productivity
I have this same issue, and I use OneDrive, however, because I have two OneDrive accounts on my computer, both a personal account and a work account due to being a remote worker, it only shows me files saved to my personal account rather than my work account, which is useless since I only use Outlook for work, but it won't show me my work files.
It used to work fine when it was recent files because then it didn't matter which one drive account was used, it just showed me the most recently saved or edited files. I am always editing files and emailing them to people for work, and this useless change has slowed down my workflow considerably.
Please change it back or at least give us the option to choose which One Drive account to suggest files from. Otherwise, you are penalizing people for using multiple One Drive accounts. This is terrible design.
