When I Compose a new email using Webmail I frequently don't want it to come from the default 'From' address. I can use the dropdown list to select an alternative From address but is there any way to remove (or hide) entries from this dropdown list or change the default From address?
While not the answer @DAB412 is looking for, I do have a possible workaround, in that if you have a particular account highlighted when you press the compose button, then the From: address is set to that accounts address.
Edit - as an example if you look at my list of accounts here
When I hit compose The From: address is set to my personal email address. If I want to send mails using my outlook.com address instead, I just highlight Outlook. The account stays highlighted until I change it, so I can compose several mails in succession using a particular account.
It's not ideal - but it's worth considering.
