What did Microsoft do with this new email format!!!   There is a reason I keep my previous emails from 2015 and back.   And don't tell me they are in the deleted file because they are not!  They are gone...I'm so pissed.  When you flip to a format this should have been tested to ensure that there is not a disruption to anyone emails and what they have sitting in it.  Don't tell tell me 3rd party, POP stuff like that.  And don't tell me I had to make a copy or archive them.  I have not had an issue with my email account for years.

I want my previous emails back.
