Managing personal Outlook.com account settings, security, and privacy
I access Hotmail using my android and web browser. I discovered that my entire safe and blocked sender list displayed correctly in my web browser AFTER I cleared the Outlook cache on my android.
EXCELLENT FIND!! Worked perfectly for me as well, having just restored all my safe and blocked sender entries that disappeared months ago. Let's just hope the Outlook Android app doesn't manage to break it all again retroactively...
Sadly it is hardly surprising this happened; the Outlook app on Android is a testament to staggeringly incompetent programmers, being riddled with major glitches which either never get fixed or get fixed briefly and then broken again within a few short months.
Still leaves another big defect with the sender lists in the Outlook browser app, where it loses the changes you make if you try to edit more than 2 or 3 entries at a time, if you were trying to consolidate several mailboxes into a single domain entry for example.
