Outlook 2019 Conversation View: How to Enable Conversations and Find Attachments

Quick Answer

In Outlook 2019 for Windows, you can group related email messages into a single conversation by enabling View > Show as Conversations. You can also enable Show Messages from Other Folders and Always Expand Selected Conversation from Conversation Settings to make related messages easier to review. :contentReference[oaicite:0]{index=0}

However, Outlook 2019 does not combine all attachments from every message in a conversation into one common attachment list. Each attachment remains associated with the individual email message to which it was originally attached. To access an attachment, expand the conversation and open the specific message containing it.

What Is Conversation View in Outlook 2019?

Conversation View groups related email messages that have the same conversation subject into a thread. Instead of displaying every message as a completely separate item in the message list, Outlook can display related messages together.

Microsoft documents Conversation View as a feature available in Outlook 2019. Conversations containing multiple messages have an expand/collapse control that allows the individual messages to be displayed. :contentReference[oaicite:1]{index=1}

How to Enable Conversation View in Outlook 2019

1. Open Outlook 2019.
2. Open your Inbox or another mail folder.
3. Click the View tab on the Outlook ribbon.
4. Enable Show as Conversations.
5. Outlook will ask whether you want to enable the setting for This folder or All mailboxes.
6. Choose the option appropriate for your mailbox.

Microsoft confirms that Conversation View can be enabled from View > Show as Conversations in classic Outlook. :contentReference[oaicite:2]{index=2}

Recommended Conversation Settings

After enabling Conversation View, go to:

View > Conversation Settings

The following options are particularly useful:

Show Messages from Other Folders

Enable Show Messages from Other Folders if you want Outlook to include related messages that have been moved to other folders, as well as messages you have sent that are stored in Sent Items. :contentReference[oaicite:3]{index=3}

This can be useful when a conversation contains messages distributed between Inbox, Sent Items, or other mail folders.

Always Expand Selected Conversation

Enable Always Expand Selected Conversation if you want the selected conversation to remain expanded so that its individual messages are easier to access. Microsoft notes that this setting applies to the currently selected conversation. :contentReference[oaicite:4]{index=4}

Use Classic Indented View

Use Classic Indented View can display messages in a conversation with indentation based on their position in the conversation. This can make longer email threads easier to understand. :contentReference[oaicite:5]{index=5}

How to View Attachments in a Conversation

Enabling Conversation View does not create a combined attachment list. Attachments remain associated with their individual messages.

To locate an attachment:

1. Find the required conversation in the Inbox.
2. Click the triangle/expand icon next to the conversation.
3. Review the individual messages displayed inside the conversation.
4. Look for the message containing the attachment.
5. Open that individual message.
6. The attachment will be displayed with that message.

A conversation can therefore contain several messages, with attachments on only some of them.

Conversation message	Attachment
Original email	quotation.pdf
First reply	No attachment
Reply All	price-list.xlsx
Later reply	updated-quotation.pdf

In this example, Outlook does not display all three files as one combined attachment collection. Each file belongs to the particular message where it was attached.

Can Outlook 2019 Show All Conversation Attachments Together?

No. Outlook 2019 does not provide a Conversation View setting that combines every attachment from every message in a conversation into a single attachment panel.

Conversation View organizes the messages; it does not merge their attachments.

If a conversation contains attachments in several messages, open the individual messages to access their respective files.

How to Find All Emails That Contain Attachments

Outlook 2019 has a built-in search capability for messages containing attachments. Microsoft documents the hasattachments:yes search query for classic Outlook. :contentReference[oaicite:6]{index=6}

Click the Outlook Search box and enter:

hasattachments:yes

Press Enter.

In classic Outlook, this search returns messages in the current mailbox or folder that contain attachments. Microsoft also provides a Has Attachments filter on the Search ribbon. :contentReference[oaicite:7]{index=7}

Search for Attachments in a Specific Conversation

If you know the subject of the conversation, combine the subject search with the attachment search.

subject:"Your email subject" hasattachments:yes

Replace Your email subject with the relevant conversation subject.

This can help identify the individual messages in the mailbox that contain attachments related to the subject. Outlook's search supports subject filtering and attachment filtering in classic Outlook. :contentReference[oaicite:8]{index=8}

Using the Has Attachments Filter

You do not have to type the search command manually. Outlook 2019 also provides a built-in filter.

1. Click the Search box.
2. The Search tools appear on the ribbon.
3. Use the Has Attachments filter.
4. Outlook displays messages containing attachments.

Microsoft identifies Has Attachments as a built-in search filter in classic Outlook, including Outlook 2019. :contentReference[oaicite:9]{index=9}

Important Difference Between Conversation View and Attachments

Feature	What It Does
Show as Conversations	Groups related messages into conversation threads.
Show Messages from Other Folders	Includes related messages stored in other folders and Sent Items.
Always Expand Selected Conversation	Keeps the selected conversation expanded.
Has Attachments search	Finds messages containing attachments.
Combined conversation attachment list	Not provided by Outlook 2019.

Reply All and Attachments

This is important when the purpose of finding conversation attachments is to send them again with a response.

When you use Reply All, Outlook does not automatically include attachments from the original message. The required files must be manually attached to the reply. Microsoft documents that original attachments are not included when replying, while forwarding an email includes the original attachments. :contentReference[oaicite:10]{index=10}

Therefore, if several messages in a conversation contain different attachments, you must identify the messages containing the required files and manually add those files to your Reply All message.

Recommended Workflow

For a long Outlook 2019 conversation containing attachments, use this workflow:

1. Enable View > Show as Conversations.
2. Enable Show Messages from Other Folders if messages may exist outside the Inbox.
3. Enable Always Expand Selected Conversation if you want the selected conversation expanded.
4. Expand the conversation using its triangle icon.
5. Open the individual messages that contain the required attachments.
6. If necessary, use hasattachments:yes to locate messages containing attachments.
7. Save or copy the required files.
8. Select Reply All.
9. Manually attach the required files to the reply.
10. Check the attachment list and recipients before sending.

Why You May Not See an Attachment When Looking at the Latest Reply

An attachment belongs to the message in which it was originally sent. If a later reply does not contain that file, selecting the later reply will not make the earlier attachment appear as though it were attached to the later message.

Expand the conversation and open the original or other specific message that contains the attachment.

Verification

After enabling Conversation View, verify that the conversation appears as a grouped thread and that the expand/collapse control is visible beside conversations containing multiple messages. Microsoft documents this behavior for classic Outlook. :contentReference[oaicite:11]{index=11}

For attachment searching, enter hasattachments:yes in the Search box and confirm that Outlook returns messages containing attachments. :contentReference[oaicite:12]{index=12}

Conclusion

For a conversation containing attachments, expand the conversation and open the individual messages containing the files.

If the files need to be sent again with Reply All, manually attach them to the reply because Outlook does not automatically include the original attachments.
