My situation is this - I have a "professional email" that I want to use and it forwards all email to my gmail account: Example: I give Foo@professional.com to others, they email that address and my firstname.lastname@example.org gets the emails. I have configured the gmail to use Foo@professional.com as the sender and reply for all emails originating from that professional account. I also setup new outlook account to look at my gmail and also set the reply to addres to Foo@professional.com. I ran 4 scenarios and here's what I noticed: 1. Send email from Gmail from PC to yahoo gets the Foo@professional.com throughout. GOOD 2. Send email from Gmail on android phone to yahoo gets the Foo@professional.com throughout. GOOD. 3. Send email from outlook from PC to yahoo - the sender is email@example.com but when replying to the sender it is the firstname.lastname@example.org account.... 4. send from android regular stock email - the sender and the email address when replying are both email@example.com... So is there any way to fix 3 & 4 so that everything will look "professional"? I suppose it is not incredibly annoying to switch to Gmail on the android but on the PC i still prefer the usability of outlook though... I also thought about creating a new gmail account like First.LastX@gmail.com as well... Thanks!
