We've been running ZCS 7.2.2 RHEL5 on CentOS 5 for some time now.
Last week I upgraded to ZCS 7.2.6, with apparently no problem.
Now, some users (not all of them) cannot see their subscribed folders via IMAP in Thunderbird anymore.
Only Inbox and Trash are displayed.
When trying to subscribe, all folders are shown in the list, but checking them and clicking on "OK" does nothing.
I have tried from a clean Thunderbird profile, but the problem remains the same.
I have an IMAP log from Thunderbird, and I believe the relevant part is :
Note that might be important : the users who have this problem use shared folders. Other users have shared folders but have no problem with their subscriptions though.
5948[7e40790]: 8ea2000:<myserver>:A:SendData: 10 list (subscribed) "" "*"
5948[7e40790]: ReadNextLine [stream=9eb6348 nb=19 needmore=0]
5948[7e40790]: 8ea2000:<myserver>:A:CreateNewLineFromSocket: 10 NO LIST failed
Thanks for your help !
