306582 - Thunderbird forgets the IMAP folders it is subscribed to with Mercury email server

Status: RESOLVED INVALID

(Thunderbird :: General, defect)

Description

[Chreag Anderson]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Build Identifier: version 1.0.6 (20050716)

When I subscribe to folders on a Mercury IMAP email server (running on Windows 
Server 2003) the folders all appear as expected. When Thunderbird is close and 
then reopened, all the subscribed to folders have disappeared, and I need to 
resubscribe to the in order to access them.
I have tried connecting to the same Mercury IMAP mailserver using Pegasus email 
and it remembers its subscriptions and I've tried Thunderbird with a different 
IMAP server and it is fine as well. 

Reproducible: Always

Steps to Reproduce:
1.Run thunderbird
2.Subscribe to IMAP folders from Mercury server
3.Close thunderbird and reopen and the folders are gone!

Actual Results:  
All the subscribed to folders have disappeared

Expected Results:  
Remembered the folders it is subscribed to

Can you try generating a protocol log by following these instructions?

trying a trunk build or 1.8 branch build might be worthwhile as well.

Attachment: Capture of the IMAP protocol during subscription and subsequent restart of thunderbird

I have the same issue as the poster of this bug. I have captured the protocol log. It does clearly show the subscription occuring and later after a restart, Thunderbird does not show it nor attempt to use the folder. I subscribed to a folder called 2006.

Yep, that clearly shows the Mercury server not telling us about the subscribed to folder on restart. Sounds like subscription might not really work on Mercury IMAP. You could try telling TB not to use subscription under Account Settings | IMAP server, server settings, advanced - uncheck show only subscribed folders,
