I have more than 40 conversations in Outlook support for Android through my app on Android.
Unfortunately Microsoft analysts do not understand what happens or they pretend they do not understand.
I already explained several times what happens but they insist that the downloaded attachment can be accessed
through the Downloads app in Android.
Yes, it can be done but the problem is that when trying to share the attachment by any other application on android,
the attachment is saved with the incorrect name.
The attachment is saved with the name DownloadFile-1, DownloadFile-2, etc. (only with the correct extensions)
Just access the /data/data/com.android.providers.downloads/cache folder on your Android device (needs root permission)
to see that Outlook is saving the attachment with the wrong name.
But in each support response they try to convince me that the application works correctly.
They even tell me it's a free application and I would not have the right to complain so much.
I think Microsoft's total lack of respect for their consumers, even more than I am of Office 365 Home subscriber.
It is lack of respect and Microsoft incompetence, which can not develop an application for Android.
And what I realized these chats I had, is that Microsoft does not care a bit about what's going on.
Well folks that's it.
In short: We are waiting for a miracle and good Microsoft's will to solve the problem,
because the Outlook for Android , it becomes useless.
Any other android email client app works correctly, with the exception of Outlook for Android.
Microsoft should ask Google experts to teach how to build an application for Androd.
It would be better than to publish an application that lets users angry and wasting time
with this useless application that is with Outlook to Android.
