MS Outlook 365 Issues After Migration to Google

Update

I resolved the duplicates in sent mail folder by changing the Outlook account settings and checking the box beside "Don't save copies of sent items"  The other two problem I've isolated as happening only when testing by sending test emails to myself.  (Stupid me for not noticing that). 

So I did transition to Google and have Outlook running well on Motorola Android phone and Samsung Galaxy Tablet.  But it has not been fun.  I am contemplating migrating myself off both Telus email and Google email and starting fresh with an Outlook.com account.
