Configuring preferences and options in Outlook.com
I basically use Firefox as my browser and some one wrote to get a Firefox add-on that blocked ads to solve the problem and it worked. I don't know if IE has any add-ons of this nature.
Also I sort of have given up on outlook.com as I find it most cumbersome to manipulate and adjust. As an example I do a lot of email marketing and I find just a simple thing of formatting the emails for proper space between lines and paragraphs is impossible to do. Who wants to send a marketing letter which has multiple spaces between each paragraph. It does not look professional. I have gone back to Outlook 2016 and find it much easier to manipulate for a decent presentation.
