I agree that this code issue is not being fixed by Microsoft, and it is annoying. I must disagree that Microsoft Tech Support is useless, although I can respect your feelings.
They are useless , each time I have contacted them , they have just made the problem worse , they are not technicians and are just reading off cue cards or prompts on their screen , then Microsoft want you to pay for advanced support , well, if this is an example of their support they can keep it , espeically when in the days of upgrading to Windows 10 i got told by a techncan "well you chose to upgrade " , terrible attitude , they are also completely oblivious to the isssues with the Mail app , there answer is to try and roll back the computer by resetting it and keeping all your files , this only causes more agravation , as it messes up your operating system , complete total waste of time !
