More 3.4 calendar woes

[Andy Kopciuch]

To me it sounds as though the messages in the Contacts folder were deleted and 
expunged.   I experienced this on a normal mail folder folder for a user 
recently (problem with an iPhone - expunged all messages).

In Kolab 3 - deleted messages can be in 3 states (not just 2).

1.  Deleted - the IMAP deleted flag is set, and depending on the client 
settings the message will still be visible to the user.
2.  Expunged - the message has been _deleted_ from the folder.   It is no 
longer available to the user.   The message does still reside on disk in the 
folder, and is mapped in the cyrus.expunge file.
3.  Expired - Cyrus (cyr_expire) will automatically run and "expire" all 
expunged messages older than 69 days ... the default value in kolab.   This is 
when the message will be permanently removed from disk.  To recover ... you 
need to have a backup.

Using some cyrus tools, and the kolab cli client, you can see expunged 
(deleted) messages and folders, and restore them within the 69 day period.

https://docs.kolab.org/administrator-guide/backup-and-restore.html

You can list all messages, and restore a single message by UID, or restore all 
expunged messages in a folder.

removing the index, and header files, and then reconstructing will reset the 
seen flag and all messages would appear as new.  If this happens to you again, 
I would check to see what the expunged messages look like, and possibly you 
can just restore them, instead of reconstructing.

Hope that helps,



Andy
