Using Outlook for Android for personal email and calendar management
Its very hit and miss. I just deleted my Hotmail account within Hub+ from my TabS5e, to try a workaround; the workaround didn't work, but was able to add my Hotmail to Hub+ without any issues, using all the Hub+ default settings.
As an experiment I setup the Samsung Mail app on my phone and that works with my Hotmail, without any authentication prompts.
Currently on Hub+ I am still getting regular password update prompts, which I now just clear; however, the app seems to be synching ok.
