Messages in an e-mail thread are automatically moved to the Deleted Items folder

When you are utilizing the Ignore feature in Outlook 2010 or later versions, messages are automatically moved to the Deleted Items folder.
This problem occurs when you select Ignore on an e-mail message and then a later message from that thread comes into your mailbox.

When you select Ignore on an e-mail message, Outlook deletes that e-mail message and it also keeps track of all future e-mail messages related to the ignored message. If a future message related to the originally ignored message arrives in your Inbox, Outlook automatically moves these future messages to your Deleted Items folder.

NOTE: This feature is not available or functional in the following configuration.
  • Online mode profile in Outlook
  • Exchange 2007 or Exchange 2003 mailboxes

To resolve this problem, remove the "ignore" status of the e-mail thread using the following steps:
  1. Select your Deleted Items folder.
  2. Select the message that is currently set to be ignored by Outlook.
  3. Click Ignore on the Delete section of the Home tab on the ribbon.

    Note You can determine if a message is being ignored by the status of the Ignore control on the ribbon. If the Ignore control is highlighted, as shown in the following figures, the conversation thread on that message is currently being ignored by Outlook.

    Outlook 2013:Outlook 2013 Ignore Conversation button
    Outlook 2010:Outlook 2010 Ignore Conversation button

  4. If prompted, click Stop Ignoring Conversation.
At this point, the message is automatically moved from your Deleted Items folder to the folder from which the message originated, and future messages for this thread will not be automatically deleted.
More information
When you enable the Ignore option on a conversation, a message is created in the Associated Contents table of the Conversation Action Settings folder of your mailbox (The screen shot for the Conversation Action Settings folder is listed below).

The associated messages in the Conversation Action Settings folder use the following rules.
  • If there is no activity on a thread for fourteen (14) days, the conversation action message for the thread is automatically deleted.
  • The age of the conversation action message is determined by the oldest message for the conversation.
  • You can modify the number of days at which the conversation action messages expire using the following registry data.

    Key: HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook\Options\Conversations
    DWORD: OnGoingActionsExpiration
    Value: Integer specifying the number of days after which an inactive conversation has its conversation action message deleted

    Note The x.0 placeholder represents your version of Office (16.0 = Office 2016, 15.0 = Office 2013, 14.0 = Office 2010).
  • You can start Outlook using the following command line to delete all conversation action messages in the Associated Contents table of the Conversation Actions folder.

    Outlook.exe /CleanConvOnGoingActions

    Note: Conversations whose conversation action messages get deleted by the /CleanConvOnGoingActions switch do not reappear back in the Inbox. The conversation remains in the Deleted Items folder. However, because the hidden conversation action message no longer exists for the conversation, any new messages for the conversation remain in the Inbox.
You can also get different behavior from this feature, depending on the version of Exchange you are using.
  • With Exchange 2007 and a cached mode profile, Ignore is based on SUBJECT. For example, any message with "Help!" as the subject will be automatically sent to Deleted Items as long as you clicked Ignore for a previous message with Help! as the subject.
  • With Exchange 2010 and later versions, Ignore is based on the CONVERSATION ID and only the messages related to the same ignored conversation are automatically sent to the Deleted Items folder.
When you Ignore a conversation you receive the following prompt to confirm the action.

In this dialog box, there is also a "Don't show this message again" option. If you enable this option, you will not be prompted to confirm the Ignore Conversation action the next time you Ignore a message. If this option is enabled, the following data is written into the registry.

Key: HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook\Options\General
Value: 63,

NoteThe x.0 placeholder represents your version of Office (16.0 = Office 2016, 15.0 = Office 2013, 14.0 = Office 2010).

Note The Pont_String value may include numbers other than 63.
