Apple Mail recently stopped receiving Gmail
In past month or so, I've had trouble getting my Gmail on Apple Mail. This has never happened before. This has been set up and working for about 1 year on this Mac, so I don't understand why it stop working. I'm having trouble on the MacBookPro. However, I can get the iPad to receive mail, and sometimes I can force the MBP to receive mail too, by first downloading it on iPad, then opening Apple Mail on MBP.
I was getting warning saying "Login failed", so I finally reset the password on the MBP. Well, I don't get that message anymore, however I am getting a popup message that says "Online Status Connections to the server "map.gmail.com" on the default ports timed out" and two buttons to Cancel or Try Again. I understand the message and realize that gmail doesn't use the default port. But there doesn't appear any way on the MBP to see what port it's using, without starting all over. I'm leery to do this since I don't store my emails on gmail, I move them to folders on the MBP, and I don't want to lose these messages.
Can anyone tell me how to fix the port problem without regenerating the gmail account on Apple Mail from scratch?
[Next day] At this point my gmail has become completely disfunctional unless I log in directly on website. My Apple mail no longer receives NOR sends email out. I think I have no options, than to set it back up again. Since all of my saved emails are on my MBP (NOT on gmail), can I just add another gmail account into Apple Mail (even though it's really the SAME ONE) and enter the correct data for my current gmail address and set it up a second time? What are my options? How do I get out of this mess WITHOUT losing the email folders that are already on my MBP?
Thanks for any assistance.
