Couple of issues. I have my iCloud account set up on the apple mail client, along with my gmail. 1. When I try to select my gmail "sent" folder as "use this mailbox as" "sent mailbox", the option is grayed out. 2. When I tried to copy my gmail inbox to icloud, it copied about 900 of my messages, but then it stopped and said it could copy no more. Can anyone help and tell me what I'm doing wrong?
