Hello,

after dealing with shared folder within version 2.0 rc* I started using it with a group of users.

user1 shares a folder to user2. user2 has access to messages of this shared folder. After a "random" time (minutes up to several days) user2 doesn't see those messages anymore. user1 (the owner) hasn't changed anything inside this folder. All messages are still in place and normal visible for him.

If user1 copies (whit TB) a messages into that folder user2 can see sometimes all messages again. But after a "random" time it happens again. user2 sees an empty shared folder. Deleting dovecot.index.log and dovecot.index.cache does not help.

I have version 2.0.11 (2.0.10 same problem). mail_gid = sysdov mail_uid = sysdov namespace { inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/maildir:CONTROL=~/control/FremdeOrdner/%%u:LAYOUT=fs prefix = FremdeOrdner/%%u/ separator = / subscriptions = no type = shared }

mail_location = maildir:~/maildir:INDEX=/addons/index/%u:CONTROL=~/control:LAYOUT=fs

I checked in a dialog: user1: 1 login user1 ... 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in 1 list "" "*" ...
