Overview
Users of Kerio Connect 10.0.6, when using Outlook connected via IMAP, may experience an issue where a copy of a message moved from the Inbox to another folder is also saved in the Deleted Items folder. This issue is consistent across all versions of Outlook and is due to the way Kerio Connect implements the 'Deleted Items folder' feature on top of the IMAP protocol.
Solution
To resolve this issue, you can either disable the 'Deleted Items folder' feature in Kerio Connect or enable it directly in Outlook.
To disable the feature in Kerio Connect, follow these steps:
- Stop the Kerio Connect Service.
- Once Kerio Connect has completely stopped, open the mailserver.cfg file in a text editor and search for the string 'AutoExpungeOnDelete'.
- Change the value from '1' to '0'.
- Save the changes to the file.
- Restart the Kerio Connect Service.
Note: Disabling this feature in Kerio Connect will apply to all IMAP clients.
Alternatively, you can enable the 'Deleted Items folder' functionality directly in Outlook by following these steps:
- Open Outlook.
- Go to File → Account Settings → Account Settings.
- Select your IMAP account and click Change.
- Click More Settings.
- Navigate to the Deleted Items tab.
- Uncheck the option 'Mark items for deletion but do not move them automatically'.
- Click OK, then Next, and finally Finish.
- Restart Outlook to apply the changes.
Summary
By either disabling the 'Deleted Items folder' feature in Kerio Connect or enabling it directly in Outlook, users can resolve the issue of duplicate messages appearing in the Deleted Items folder when using Kerio Connect 10.0.6 with Outlook via IMAP. If this behavior continues to pose challenges, consider using alternative protocols such as EWS, ActiveSync, or POP3.
