+# The Offline Address Book (OAB) does not display the Global Address List by default
+
+_Original KB number:_   2665915
+
+## Symptoms
+
+When Microsoft Outlook is configured in Cached Exchange mode and you open the Address Book, the global address list (GAL) isn't displayed by default. Instead, another address list such as **\All Users** is displayed, and the GAL must be manually selected from the **When opening the address book, show this address list first** Address Book option. This is demonstrated in the following figure:
+
+:::image type="content" source="media/offline-address-book-not-display-global-address-list/address-book-option.jpg" alt-text="Screenshot that shows Address Book option.":::
+
+You may also receive an error message that resembles the following error in a synchronization log message when you try to download the Offline Address Book (OAB):
+
+> Microsoft Exchange offline address book  
+Not downloading Offline address book files. A server (URL) could not be located  
+0X80004005
+
+In the situation where you can't download the OAB, you'll find the following event in the Application event log.
+
+> Source: Outlook  
+Event ID: 27  
+Description: The operation failed.
+
+## Cause
+
+This behavior may occur if multiple address lists are included as part of the Offline Address Book (OAB) generation on the server that is running Microsoft Exchange Server.
+
+This can also occur in Outlook when the **When opening the address book, show this address list first** option is set to **Choose automatically**.
+
+When multiple address lists are included in the OAB, each address list is built as an OAB and is available for download to the Outlook clients. In this scenario, when Outlook receives the list of available OABs, it doesn't necessarily download the one for the GAL by default.
+
+## Resolution
+
+To resolve this issue, set the GAL as the only address list for which an OAB is generated on the Exchange server. To do this, follow these steps:
+
+1. Open the Exchange Management Console.
+
+1. Expand **Organization Configuration**.
+
+1. Select **Mailbox**.
+
+1. Select **Offline Address Book**.
+
+1. Right-click the default OAB, and then select **Properties**.
+
+1. Select **Address Lists**.
+
+1. Select to clear the **Include the following address lists** check box.
+
+    :::image type="content" source="media/offline-address-book-not-display-global-address-list/include-the-following-address-lists.jpg" alt-text="Screenshot that shows the Include the following address lists check box.":::
+
+1. Select **OK** to save the changes.
+
+After you make this change on the Exchange server, any new Outlook profiles that you create will use the OAB with the GAL by default.
+
+> [!NOTE]
+> The Microsoft Exchange server generates updated offline address book files at a 24-hour interval. Therefore, at worst it can take 24 hours for a new Outlook profile not to exhibit the problems described in the "Symptoms" section.
+
+## Workaround
+
+For existing Outlook profiles, you can manually change the OAB that is downloaded to the one that is built from the GAL by following these steps for your version of Outlook.
+
+- Outlook 2010 and later versions
+
+    1. On the **Send/Receive** tab, select **Send/Receive Groups** and then select **Download Address Book**.
+
+    1. In the **Choose address book** drop-down, select **\Global Address List**.
+
+    1. Select **OK**.
+
+- Outlook 2007
+
+    1. On the Tools menu, point to Send/Receive, and then select Download Address Book.
+
+    1. In the **Choose address book** drop-down, select **\Global Address List**.
+
+    1. Select **OK**.
+
+> [!NOTE]
+> The Microsoft Exchange server generates updated offline address book files at a 24-hour interval. Additionally, Outlook clients automatically download offline address book updates every 24 hours. Therefore, if Outlook is left running until the automatic OAB download occurs, it can potentially take up to 48 hours before the problems described in the "Symptoms" section are resolved. You can circumvent the Outlook interval by manually downloading the OAB. However, you must still account for the Exchange OAB generation that can be delayed by up to 24 hours.
+
+## More Information
+
+In Outlook 2010 and later versions, the **Choose automatically** option is the default option for compatibility with the multiple Exchange accounts feature. In configurations in which multiple Exchange accounts are configured, the **Choose automatically** option lets the correct GAL be displayed for the selected Exchange account.
+
+1. To set the default address list when you open the Address Book in Outlook 2010, follow these steps:
+
+1. Open the Address Book by clicking the ribbon icon.
+
+1. On the **Tools** menu, select **Options**.
+
+In the **When opening the address book, show this address list first** drop-down list, select the default address book.

+# Messages in an e-mail thread are automatically moved to the Deleted Items folder
+
+_Original KB number:_   2697913
+
+## Symptoms
+
+When you use the **Ignore** feature in Microsoft Outlook 2010 or later versions, messages are automatically moved to the **Deleted Items** folder.
+
+When this problem occurs, a message trace indicates a **DefaultFolderType:DeletedItems-Conversations Processing Agent** event. Email messages that trigger this event are delivered directly to the **Deleted Items** folder.
+
+## Cause
+
+This problem occurs if you select Ignore on an e-mail message, and then another message from that same thread is delivered into your mailbox.
+
+When you select **Ignore** on an e-mail message, Outlook deletes that e-mail message and also keeps track of all future e-mail messages that are related to the ignored message. If a future message that is related to the originally ignored message arrives in your Inbox, Outlook automatically moves that future message to your Deleted Items folder.
+
+> [!NOTE]
+> This feature isn't available or functional in the following configuration:
+>
+> - Online mode profile in Outlook
+> - Microsoft Exchange Server 2007 or Microsoft Exchange Server 2003 mailboxes
+
+## Resolution
+
+To resolve this problem, remove the **Ignore** status of the e-mail thread. To do this, follow these steps:
+
+1. Select the **Deleted Items** folder.
+
+1. Select the message that is currently set to be ignored by Outlook.
+
+1. On the **Home** tab on the ribbon, select **Ignore** in the **Delete** section.
+
+    > [!NOTE]
+    > You can determine whether a message is being ignored by the status of the **Ignore** control on the ribbon. If the **Ignore** control is highlighted, the conversation thread on that message is currently being ignored by Outlook.
+
+1. If you're prompted, select **Stop Ignoring Conversation**.
+
+At this point, the message is automatically moved from your Deleted Items folder to the folder from which the message originated. Future messages for this thread won't be automatically deleted.
+
+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 screenshot for the **Conversation Action Settings** folder is listed in the following screenshot.)
+
+:::image type="content" source="media/message-automatically-moved-deleted-items-folder/conversation-action-settings.png" alt-text="Screenshot that shows the Conversation Action Settings folder.":::
+
+The associated messages in the **Conversation Action Settings** folder use the following rules:
+
+- If there's no activity on a thread for 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 by using the following registry data.
+
+    **Subkey**: **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, Office 365, and Office 2019, 15.0 = Office 2013, 14.0 = Office 2010).
+
+- You can start Outlook by 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 don't reappear 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 Server that you're using:
+
+- In Exchange Server 2007 and a cached mode profile, "Ignore" is based on SUBJECT. For example, any message that has "Help" as the subject will automatically be sent to Deleted Items as long as you clicked **Ignore** for a previous message that had "Help!" as the subject.
+
+- In Exchange Server 2010 and later versions, "Ignore" is based on the CONVERSATION ID, and only the messages that are 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.
+
+:::image type="content" source="media/message-automatically-moved-deleted-items-folder/ignore-conversation.png" alt-text="Screenshot that shows the Ignore Conversation dialog box.":::
+
+In this dialog box, there's also a **Don't show this message again** option. If you enable this option, you won't be prompted to confirm the **Ignore Conversation** action the next time you select to 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**
+**String**: P**ONT_STRING**
+**Value**: **63**
+
+> [!NOTE]
+> The <x.0> placeholder represents your version of Office (16.0 = Office 2016, Office 365, and Office 2019, 15.0 = Office 2013, 14.0 = Office 2010).
+>
+> The Pont_String value may include numbers other than 63.
