Hello everyone. I have a Gmail account that I access via IMAP with my iPhone, iPad, and iMac. This morning, I noticed that nearly everything was gone, only the last few weeks of emails was in the inbox. There were a few more weeks of email in the trash, but I have used this account for several years and there are a few thousand messages in there. It's not worth figuring out how this happened, but I have a question. I have a laptop that I let a friend borrow for a project, and she logged into my account (with Wi-Fi disconnected) to see that all the emails still there on my local machine. I use Airmail and macOS Mail to access this account, and the messages are there on both. The moment I connect this machine to the internet, it would synchronize with Gmail's servers via IMAP and delete the rest of these messages. I have changed the Gmail password so these applications can't get sign on, but I'm still nervous because I really want to back up these emails. Using Airmail and/or macOS Mail, how can I export these inbox (and sent) messages? Ideally I want to bring everything back into Gmail for their searching tools, but I just don't want to lose them entirely. Neither of these applications are very user friendly for backup/export of messages. How can I do this safely? Thanks!
