I am very happy to report that this is now working for me.
I’ve upgraded my phone to the latest Fast Insider build (OS build 10.0.15047.0, Outlook Mail version 17.7906.42258.0), tried sending a couple of test emails over several different email accounts. When looking at the received messages for all of them, I can now see my name as well as the email address in the From field.
Note that when the message is composed in the phone Outlook Mail app, the From field on top of the screen still shows only my email address. However, this is not a problem since the message is now sent out with the full “Name Surname” <my@email.com> in the From field in the email message header.
It has been a long wait, but I wanted to say ‘thank you’ to all Microsoft people who got this prioritised and fixed. Many of us don’t fully appreciate all the issues and internal politics these guys have to deal with day-to-day. I am imagining that in the end there was someone who said ‘come on people, let’s fix this, it is embarrassing!’
Many thanks also to all of you who raised this issue with Microsoft and on the Forum, helping this to get more visibility.
This fix makes a massive difference to me. Now, 6 months after buying my Lumia, I can finally respond to my business emails on my business phone, magic!
I am easily pleased, obviously… :smile:
PS: Now, the only other thing I am still missing is the Tasks app (and Notes!) for W10 Mobile which is fully compatible with Outlook and can sync with Exchange… There must be another thread on this already!
