I am trying to migrate an email account from outlook webmail to thunderbird, but only the inbox has synchronized. The subfolders within the inbox, the sent and drafts folders do not appear. Under message synchronization within the synchronization and storage tab, I have tried both with the box "Keep messages in all folders for this account on this computer" ticked and unticked: when I go to "advanced", no folders appear except inbox and trash, so there is no way to select them. I have consulted this page: https://support.mozilla.org/en-US/kb/imap-synchronization#w_configuring-synchronization-and-disk-space-usage but as mentioned above, I cannot find any way for folders except for trash and inbox to display within thunderbird. I was able to download all the emails from my inbox, and am receiving incoming emails. Any advice would be very much appreciated. Thank you in advance! Marie
