Many users ask about editing the subject line of messages, usually because they plan to save the make the subject more better reflect the content of the message.

This is possible – and simple – just open the message, select the subject and begin typing.  You don’t even need to do anything special, beyond opening the message. You can select the subject and type over it or backspace to delete all or part of the subject, or add to the subject.

After editing, click Save to commit the changes, or click close and don’t save to revert to the original subject.

You can also edit the subject when using a list view with in-cell editing enabled.

For information specific to Outlook 2010 and Outlook 2013, please see Editing the Subject line in Outlook.

In an Open Message

You can change the subject line of an open message. The subject field doesn’t look editable, and appears grayed in older versions of Outlook which usually means you can’t make changes, but you can still click in the subject area and start typing.

Click in the subject field and start typing

In an Outlook View

You can make the subjects editable in the Outlook message list when in-cell editing is enabled.

Note: In Outlook 2003 and up, in-cell editing works only when the message list is using a single line view. When you use Conversation view in Outlook 2010 or 2013, you’ll need to have more than one message in the conversation to use in-cell editing. If there is only one message, turn off view by Conversation.

In Outlook 2010 or Outlook 2013, look for the option in View ribbon > View Settings or click on the row of field names and choose Customize > View Settings. Click Other settings button to open the dialog shown in the screenshot.

You’ll see an option for Allow in-cell editing. Check the checkbox, then click OK, and you’ll be able to edit the subject of any item in the folder, without the need to open the item first.

Enable In-Cell editing

In Outlook 2003 and Outlook 2007, go to View > Current View > Customize view > Other settings button or click on the row of field names and choose Customize > Other settings.

If you are still using Outlook 2002, 2000 or 98, go to Choose View > Current View > Customize Current View > Other Settings button.

      The original text still exists on the message, so it should be possible. But I never tried it.

      In Outlook 2013, I'm finding the messages using the old subject - i did not restrict the search to the subject, which allowed it to search all fields, including the conversation field.

  1. Big VBA user says

    Related question: Is there a way to toggle "Allow in-cell editing" on an off *via VBA*, rather than "by hand"? (It would be a great if there is!). Thanks very much.

    • Diane Poremsky says

      You can, but i don't have any good samples that use it. This is from MSDN:

      Property AllowInCellEditing As Boolean
      Dim instance As _TableView
      Dim value As Boolean
      value = instance.AllowInCellEditing
      instance.AllowInCellEditing = value

  2. Zsolt Ferenc Juhász says

    Is there a way to see the changed subject in the Conversation List too. Because, thats the reason Why I want to changs the subject line - to group them together based on the Subject...

  3. Alfonso Gonzalez says

    If the subject is changed in my outlook (inbox), this change is replicated in the Exchange DB? In other words, if I have two computers running Outlook synced with an Exchange Server and I change the subject of an email in computer A, is this change replicated in computer B when I open Outlook in such computer?

  4. kurt says

    is there a way to make just one column editable. I want a column next to subject column to be editable but i do not want the subject line to be editable.

    • Diane PoremskyDiane Poremsky says

      Open View Settings > Columns and add the Changed By field to the view. That will show the last account to make any change to the message. However, it only shows the last account that made a change so if someone changes the subject and another forwards it, you'll only know who forwarded it.

  5. Debbie Kennedy says

    I want to auto edit the subject of all incoming emails with the sender and date and time. We are not allowed to keep pst files so this would help me find emails when I copy them to network drive - I can't find any way to do this
