We utilize Sharepoint Online for work documents and last week I was sent a new spreadsheet and couldn’t access it. I use IE for all work stuff and the browser was telling me that Sharepoint Online couldn’t find my user account. I fixed this by clearing all cache and cookies several times which didn’t work until I told IE not to remember anything. Apparently MS has an article out there saying to stop using IE. I’ve disliked IE since MS decided to kill off Netscape in the 90s. Honestly I wish I could get a MacBook for work but for some reason our management is trying to get rid of them in our department.
