It works well for me. Besides 365, etc I also use Chrome on my Mac, and that works well for outlook.com and office.com. You can also download the MS Remote Desktop tool if you do any server admin or connect to any other desktops.
I'm reaching out to try to get you some more advanced help here. My only thought is to have you do a clean install with your windows 7 disk, IF you still have it. You will probably lose all your data, though.
You can post images via advanced options, OR using the picture frame icon on the posting box.
PS You will be missing some of the options that I have (Moderator functions), but you should see the picture frame.
Looks like a decent model. I have a different, older Anker model that I use and like. I also found the model you are looking at, 10 to 15 dollars cheaper on Amazon...
Unfortunately I can not provide an answer, but wanted to let you know I deleted the other post for you. :) Hopefully someone will come along shortly and provide an answer. :)
