IMAP Useless with Zimbra 7.1? LSUB Failed! after deleting Subfolder in Shared-Folder

[gantscha]

We have a brand new installtion of Zimbra 7.1 on Ubuntu x64

IMAP Connection of Outlook and Thunderbird clients seems to be broken:

If we delete a Subfolder in a Shared Folder Thunderbird and Outlook is broken: The error Message is LSUB failed. In mailbox.log the following error message appears:

2011-06-30 09:49:42,809 WARN [ImapSSLServer-51] [name=user@domain.at;ip=910.113.220.140;] imap - LSUB failed

At this Point Thunderbird and Outlook is no longer able to mount ANY IMAP Folder except Inbox and Trash?!?

What is going on?!? Are there Traces of this Folders left somewhere? Is IMAP implementation broken?!?

If i recreate this previous deleted Folder Thunderbird and Outlook are working again but this would imply that i can never ever delete a shared folder again?!?

PLEASE HELP!:

[gantscha]

After a bit more testing i am pretty sure that some sort of "trace" of this folder still exists after deleting it?!? But i am not sure where i could/should search? Why are the IMAP clients still searching for it? Why doesnt zimbra tell the IMAP client that the folder wont exist any more?!?

By the way: It does work with local folders -> only the deletion of Shared Sub Folders breaks the IMAP Clients Thunderbird and Outlook

[gantscha]

After even more testing i guess it has to do with the "Trash" feature?!?

If i delete a folder it is moved to the thrash folder right?!? -> IMAP is still working... After emptying the trash folder IMAP ist broken and in mailbox.log zimbra complains about missing folders like folder missing /Trash/Foldername.

So it seems to me that emptying the trash and moving folders to the trash is broken?!? -> Just an educated guess...

With this in mind i am also curious what the "Dumpster folder" feature in cos is for? I enable it at first and later on disabled it while trouble shooting the imap problem -> nothing really changed after disabling it - There is still a trash folder and everything is moved into thrash?!? -> Just wonderring if this new option/feature could be related to this problem?!?

[gantscha]

After 16 hours of trial and erro i still cant find a cause -> Why is thunderbird and outlook are still looking for those deleted folders even after deletion?!?

Am i the only one with this behaviour? If this is a persistent error i have to downgrade to zimbra 6 or choose something else -> Its a disaster honestly...

If there is any one out with the same error or anybody with some sort of hint - PLEASE report back in this thread!

I'd suggest that you open a ticket. I don't use shared folders with IMAP, so wouldn't have seen this issues.

This is just a workaround but nevertheless - I ran into the same problem with a shared, then deleted Contact group Contacts/whatever. What I did was create the very same thing again, not shared, rerun Thunderbird, everything ok. Then, delete that local group from the web interface, including throwing it out of the trash can. No more problems.

Like I said, not a solution for the root but works for me now :-)

Gantscha, are you using Symantec Endpoint security somehow? This one is known to break not only IMAP client, but also server-side IMAP UID, which may lead to problems.
That's my experience.

We have the same problem at our installation.
I've reported this to zimbra and hopefully they'll fix that issue soon.

Also a bug entry exists:

If you look at the bug report you'll see that it has been fixed and if your check on the Product Portal you'll be able to find out in which versions it's targeted for release (subject to verification adn QA).

Hi Bill,

Thanks for your advice. I checked the product portal and this bug 61435 missed the 7.1.2 patch by 5 days. The bug is included in the 7.1.3 patch. If we go by the release timings of the last few patches, we can expect the 7.1.3 patch to be released sometime in November.

For those of us who would like to be able to access their email folders in the next two months, do you have any suggestions?

Thanks.
