IMAP Folder Issues

My email account has alot of IMAP folders, some with sub folders a couple deep.

Only a small selection of the top level folders are shown, I go to subscribed folder and most of the folders are missing from the list. This issue only happens on Windows Thunderbird, if I do the same thing on Mac Thunderbird all folders are shown in the subscribe list.

This issue only seems to occur on Windows, thunderbird on Mac does not have the issue and the issue does not happen on any other device either, mac, iphone, tablets, android and web mail all appear to list all folders and emails.

Its my own server, using Postfix and Dovecot. Seems to only be this account with the issue but it has alot of folders compared to the rest, and its only occuring on Windows systems.

Nope both do not have same anti virus.

as a test disable anti virus. IT at times slows the communications enough that timeouts occur and things just fail.

Otherwise I suggest that you log the connection. see if that sines some light into any dark corners.
