I use Thunderbird 128.2.0esr (64-bit) to read mail from the Outlook server; these are the folder mappings: imap://<email>@outlook.office365.com/INBOX imap://<email>@outlook.office365.com/Sent imap://<email>@outlook.office365.com/Drafts imap://<email>@outlook.office365.com/Trash I used to also be able to read the Junk Email folder from the Ourlook server the same way, but the folder disappeared from my Thunderbird a couple of months ago. I tried re-adding it as a sub-folder, which is how I created it in the first place, but it won't appear on the list. I'm not sure what else to do here. I don't know where the Thunderbird directories are stored locally any more, I'm using Ubintu 24.04.
