Work offline?
I've always used the native email client on my Mac, but they've taken away the ability to work offline in Mail. My work email requires a VPN, which I don't want to run all of the time.
So, if I'm using my computer with no VPN, my email consistently errors out. Even if I disable the account, there's still something in the background checking for new email, and then erroring out. I used to just click on the mailbox and then select "take account offline." That is no longer even an option. To prevent it from checking for new messages, I would have to delete the mailbox completely. That's not something I want to do every time I need to use my own computer for personal use.
I'm thinking of switching to Thunderbird as my email client, which I have to get permission to do for that account... I wanted to find out before I jump through too many hoops if Thunderbird still allows you to work with an account offline?
