I have several email accounts that I send and receive from -- either on my iPhone 6s or on my laptop. One email account is for business & one is for personal. When an email from the business email account is sent from my phone, the wrong name is listed as the sender (my former assistant's name) -- but only when sent from my business email account on my phone. When I email from my business email on my laptop, it is listed as from my business name (which is how I want it).
Also, strangely enough, when I send an email on the phone from the business email to my personal email and open it in my personal email account ON MY PHONE, it appears correctly as from my business name (that's the only time it looks right when sent from the phone business email account). BUT if I open this same email in personal email account on my laptop, it's wrong. And anyone else who gets something from the business email, it is wrong (again, only if sent from my phone).
When I do a search on the phone in contacts app under the business email address, the business name correctly comes up. When I do a search under the former assistant's name, it comes up empty. I cannot for the life of me figure out how to get her name off as the sender! I use an iPhone 6S, most recent iOS version (11-something, I think), and I have a plan with Verizon. I access my email via google gmail.
