For anyone using Outlook.com and Alias addresses. I hope this helps someone, as I just went through this headache with Microsoft.
There IS NO WAY to send an email addressed “FROM” any of your additional Alias addresses in Outlook.com. Not from third-party software, Not from ANY Android or iPhone email applications…not even Outlook (PC) 2007 or 2003. NONE of them can do this. It has nothing to do with EM Client.
It is a basic function of the Outlook.com service and the way Microsoft built it. The ONLY way to send email from an alias address is by logging into the website through a browser. Otherwise, all email are automatically “sent” from your default address. I’ve tested this over and over for weeks and is confirmed by an Outlook.com service manager I dealt with.
As for Microsoft, Outlook.com, and the aliases…yet another example of how they totally SCREWED it up. Aliases are absolutely worthless based on this but Microsoft doesn’t see it as an issue to be corrected.
At least using EM Client can help this situation in a way no other client or app can…
Set up the Outlook.com website as a WIDGET. It stays open and allows me to send an email “directly” from the website. The only down-side is that CUT and PASTE functions don’t work.
Hope this helps
