I've followed all the recommended steps for disk space limitations and still cannot download emails. Recommendations please.
I'm running the latest OS on my iMac, and I do not use anti-virus software. I have deleted all but a few emails from my Trash and compacted all folders. The Alert message, "There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again." continues to appear.

the issue can be caused by a lack of physical disk space, a lack of quota in the disk (user account full), file locking and contention (such a an anti virus or backup program trying to access the same space at the same time. Time machine features in some peoples problems) or as the message suggest large Thunderbird files. As you have looked at the Thunderbird issues, perhaps it is time to look t the broader picture.
