I am on Windows 10, have been using Windows mail, but decided to move to Thunderbird at last, because of missing Windows Mail features. I installed Tbird 78 last night, and configured two email accounts (both IMAP). One is AOL/AIM, the other is SaskTel.net (using ZenDesk). All of the folders came over from AOL (using AIM servers), none from SaskTel. I have both accounts set up identically in terms of'' server settings''. Under the ''sync and storage settings'', I am not given the option to pull in the folders for offline use for the SaskTel email, but I am given the option for the AIM one (Items for Offline Use); SaskTel does not support client software like Tbird. All comments in this forum in relation to missing folders talk about restoring from backup after an upgrade, but I obviously don't have them backed up - they've not been there since the install. I suppose I could have imported from Windows Mail, but I should be able to do a clean pull from the server, right? And if I imported, would the missing folders continue to be active in real time? '''Bottom line: how do I get the folders to show up and populate in the SaskTel.net email? '''
