Outlook no longer letting me sign in

Hi! I am having issues signing in after the following issues (i am on a mac).

Logged in yesterday and could search my email at all, would see emails in my feed, search for that email and nothing would come up in any variety. I went online, and was told to delete the profile from this folder "~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/"

After that, out look would no longer let me sign in. I get errors such as this. 

I am not sure how to proceed and really need this to work for my job. 

I have tried restarting my computer, deleting the application and redownloading, restoring from back up(but I dont have a back up so this is not a solution).
