  1. My outlook is not working and shows the message ” cannot start the microsoft outlook. Cannot open the outlook window. Invalid XML, the view cannot be loaded.”

    Please suggest

  2. I’m having an issue that I’m convinced is a flaw in Windows 10 that is affecting the font for incoming emails to Outlook if the email is sent from an Android or an iPhone. The font for the incoming email automatically changes to the Office default font ‘Calibri 11’ even though it was not sent in that font from the phone. This issue only happens in Windows 10 with Outlook or Gmail but not in Windows 7 which I have on another computer. I’ve spent hours and hours on the phone with Microsoft and other IT options and can not find the fix. Ever heard of this issue? Thank you.

  3. it worked. omg thank you so much. i have been struggling to get it right for a week now and it was such a hinder for my work
