I'm aware that the date, time and such columns as those cannot be edited, but I've viewed a tutorial where a "Notes" column can be inserted and edited to contain notes the user wishes to see.  Unfortunately, my Outlook 365 allows me to add the column, and to enter edit mode, but it will not take any data ... I get an error tone.  There must be many other columns that allow the user to enter or edit data, or ... ?

Is there a way to add the same text to the beginning of all the subject lines all at once rather than needing to insert the text one at a time?  If so, can this be done with using VBA or a third-party app?

This is a huge game-changer for me. Thank you so much!!! It's a happy day! :-)

could i change date or time of incomming emails?

could i change reciefed from or sent to inthe header?

Having Conversation View on is the reason Subject Lines weren't editable. When I uncheck the box in View > "Show as Conversations", I'm able to edit. However, this poses a different problem - I heavily depend on viewing my emails as Conversations. Setting this view back on, now every newly changed email shows the old subject line text. Is there a way to enforce the new subject line text for Conversations?

Step 5 is missing information. I've followed every instruction exactly; my Outlook looks just like the screen shots here. "Now in the Message List, please click the subject line you want to change, and then edit it directly as below screenshot shown" - How do you get an email Subject Line into edit mode? Selecting an email in Message List does nothing but select/highlight it. Double-clicking opens it into separate window. Right-clicking shows no option for editing. F2 shortcut on a highlighted/selected line does nothing. Just start typing - nothing. ... I'm using Office 2016. Thanks

Hi, at work we use Outlook 2010. I have tried and tried, I do change the subject of the messages, but but in the MESSAGE LIST the subject is the original one while in the READING PANEL the subject is the one I have changed. So the change is not exactly complete. I have visited other help options sites and no way, the result is always the same: subject changed in the READING PANEL and unchanged in the MESSAGE LIST. Thanks anyway.

This was great! thanks for the clear instructions

Oh thank you so much, this has been driving me crazy and Microsoft and even outlook help was zero help. Your pics also made it a breeze. I fee like I have won a lottery!
