SharePoint online was working fine, until i tried to install a web app. It crashed the site and now SharePoint (and OneDrive for business) is unavailable at our office. They both fully function at other locations like at home though which makes me believe that a network setting got changed here. Exchange is still working, but anything related to SharePoint will bring up a page that states " This webpage is not available". I have also checked all internet options, and nothing is being blocked.
I have been working with a "Microsoft support rep" the last two days and have gotten no where. Can someone please help me make sure there is nothing wrong on my end.
