How to prevent deleted e-mails from disappearing permanently

Last week our support team reported interestingly some similar questions from unrelated users circling around the topic: “I accidentally deleted some e-mails. Can I get them back?”

As often in complex support situations, the answer to this question is: It depends.. 🙂

Users were pointed to this knowledge base note. This answered the questions, though with some confusion. In this post we will lay out the options.

Your Kolab Now account offers a variety of settings that lets you adjust your mailbox according to your wants and needs. When it comes to how Kolab Now manage deletion of e-mails, the configurations can be found at: “Settings-> Preferences -> Server settings”:

The settings can be explained as this:

Mark the message as read on delete: With this option enabled, unread messages are also flagged as read when they are deleted.

Flag the message for deletion instead of delete: Email messages can be flagged as deleted first before they’re finally removed from a folder. That also makes it possible to “undelete” them later on. In order to finally delete them, use the Compact command.

Do not show deleted messages: This option suppresses messages flagged as deleted from being listed. When this is not checked, the deleted messages will show up in the list as greyed out:

Directly delete messages in junk: Messages in the Junk folder are moved to the Trash when deleting them. Skip that step by enabling this option.

Clear Trash on logout: As the option name says, this will empty the Trash folder when you logout.

Compact Inbox on logout: This will remove all messages flagged for deletion from the Inbox when you logout.

Let us conclude from this – what settings are recommended to prevent deleted e-mails from disappearing completely?

  1. Enable: Flag the message for deletion instead of delete
  2. Disable: Do not show deleted messages
  3. Depending to your wants and needs, enable: Clear Trash on logout

Please note: Flagging messages for deletion instead of deleting them and at the same time hiding deleted messages can give some confusion with regards to the disk usage.
