Receiving email on multiple devices
I recently had to change my email password because of hackers. Now, receiving my email on one device messes with being able to receive on another.
I have a Mac Pro running 10.10.5, a Macbook Pro running 10.9.5, and an IPhone. I want to be able to receive all my emails on each device even if I've already received it on one of them.
For instance, this morning I received several emails on my Macbook. I didn't delete them or anything, I just received them. Then, when I checked my email on my Mac Pro, none of them came through.
I'm using Comcast email as my provider.
What setting has changed and how do I change it back?
Thanks
Mac Pro, OS X Yosemite (10.10.5)
