I am synching my outlook.com email across my desktop, tablet and windows phone. Over the past 3 weeks, the Windows 10 Mail app on each device shows the majority of (but not all) attachments as "Download Failed".
The attachments failing include, jpeg, pdf, docx, xlsx etc.
I am able to download the attachments manually from outlook.com.
It is not antivirus or firewall related, as I am running different options on the different devices.
Are others experiencing this issue and are there any known solutions.
