Post dating email outlook
As long as you don’t touch anything in the portion of the message where the attachment is (it will look like programming code), it should remain unaffected when you import the message back into the mail client. As long as you use a text editor that’s proper for the job (again, Notepad to the rescue here), the message will not be corrupted. Bear in mind that like with "Date" and "Received", you may also have to deal with additional headers depending on which mail client sent the message originally. Can I use this method to modify emails sent by me in the past?If you were placed in the situation where you forwarded all your mails to your new email address and want to change them back to how they were originally without the forwarded information, yes you can do this. The import of emails is completely different from the mail server actually sending them.
As to why different clients use different mail headers, I have no idea.
Now I have this (I also removed the "Fw:" portion of the subject line): The only other header I look for is , and if I see it, I modify the dates for those as well: Important note: "Received" may or may not be there within the email, but if it is, you’ll need to change it to match "Date", otherwise Windows Live Mail will read Received first and ignore Date completely.
Once modifications are complete, I save the file and exit the text editor.
For Windows Home, make sure that you have Version 10 (Build 10240) or higher.
If you're not able to install the update or the issue isn't resolved after the update, use the workaround below.
