Managing personal Outlook.com account settings, security, and privacy
I'm having this problem with the Outlook App on Android. When I try to download an attachment, it appears to download, but the file does not then appear in the Downloads folder. I don't have this problem with my gmail account.
This has been happening since I started using the app a few months ago, despite the app updating at least once. Seems to me lots of people are having similar issues with attachments.
Sort it out, for goodness sake!
