Hello, I use Thunderbird daily on both my mac at work (university) and my mac at home. Usually everything goes smoothly and emails are always synced between my computers. Right now it seems like something goes wrong. When I create a new subfolder in thunderbird on my mac at home it doesn't appear on my mac at work. And vice versa: when I create a new subfolder in thunderbird on my mac at work it doesn't appear on my mac at home. However, if I use the web UI provided by my employer to check my email both newly-created subfolders appear correctly, meaning that everything seems to be OK on the server side... Both my macs run the latest version of thunderbird. This is driving me crazy. Can you help me out here? Thank you very much in advance for your help. Best, -J-
