Possible to watch movies I purchased on XBOX One on my Apple iPhone?

What you're saying is not wrong, but it does not address the question asked.  The question is regarding movies purchased from the Microsoft store, not movies purchased from an alternative ecosystem with a compatible XBOX app. I have purchased movies from the Microsoft store and was asking if I can watch THOSE movies on my iPhone.

The confirmed answer, NO, has been marked on this thread. It is not currently possible to watch movies purchased from the Microsoft store on your iPhone.

I stumbled on this thread while googling how to fix my problem.  After purchasing a new pc laptop I was given $50 to spend in the microsoft store.  Without thinking I spent it on movies figuring that I would simply add them to my iphone or ipad to watch.  Basically what I've done with movies purchased from other sources.  However I can't import the movies to itunes after downloading.  I'm also unable to play the movies on any apps other than the movies and tv app on the laptop.  I tried opening them in vlc, gom player, you name it.  Then I decided to do what I do with other movies downloaded from outside sources.  I used Replay Converter to try to convert the downloaded purchases so that they would be a recognized format in itunes.  It didn't work.  I'm at a loss and it makes no sense to me why microsoft did this.  I've never run into this issue when purchasing movies from other sources.  Yet friends with Androids are able to watch movies that they purchased on their laptops through itunes.  Isn't that interesting?  Thank goodness I didn't actually use my own money to purchase anything from the microsoft store.  Just a shame that I probably won't get to enjoy these movies.  O_o;

Hi.  The issue you're experiencing is the very issue I was having, which prompted me to start this thread discussion.  I've since come to appreciate that Apple, Microsoft, Google/Android, etc have their own ecosystems within which content such as music and movies are confined within their respective ecosystem. It is therefore, up to the consumer (you and I) to decide which ecosystem you will purchase said content. You will have to weigh that decision based on your individual setup and needs.  In my case I have an iPhone and a bunch of Mac computers and will soon get an Apple TV (once Apple irons out their TV contract service). But I also have an XBOX One where I watch HBO, Showtime, Amazon Prime Video and Netflix. Since it is not possible to share movies and music across platforms, I've decided that going forth I will only buy movies from the Apple ecosystem - this way I can always port the videos to my iPhone and stream them to my TV and Mac computers.

In your current situation you do have the option of watching movies that you purchased from Microsoft on your Apple computer (or any computer for that matter) by just signing into your Microsoft account and playing the movie there. Of course this is also available to you if you have a Microsoft tablet and/or phone, but it is NOT available to you if you have an Android tablet/phone or iPad/iPhone. So, determine which platform will work best for you and buy with that ecosystem.  Lame, I know, but that's the way it is.

Cheers!

Microsoft needs to get an app out pronto or I'll just buy my movies from other vendors.
