Have a new work smart-phone. Our business uses gmail (but use our own domain). My phone flashes red for new mail, even if I have read the messages on my desktop. Any ideas how to fix?
How did you set the accout up in your phone? POP or Imap
If pop it won't sync with your phone.
Be sure to set it up with IMAP or even better Activesync.
I have my domain with google and when setup with Activesync everything syncs and the mail is on my phone instantly. When read somewhere else it syncs and shows read on the phone.
