Exchange – Emails in sent folder have no sender information in header

Question

Hey Everybody,
when I send emails with my exchange account in mail.app the copy of the email that is stored in the sent folder is missing the sender information in its header. The "from" column is empty, however, it should say my name there.
Pretty annoying because I use smart folders to organize my mails that depend on the sender information in the header. The only workaround I found so far is using imap in mail.app instead of exchange – but that's not a really satisfying solution.
I only have this problem when using mail.app with exchange. When I use the outlook.com web interface to send emails they are shown correctly in the sent folder in mail.app. Same goes for sending mails via exchange from my iPhone. My MobileMe account also works perfectly in mail.app. For the receiver there is no problem either - my name is correclty displayed as the sender.
Is anybody else having that problem or knows or solution?

Open Apple Contacts and verify your contact as "My Card". Microsoft calls this card "This is me". It's not stored on Exchange but in the local Outlook Address Book. I don't use Exchange  so not sure if Apple will let you select your contact on Exchange contacts. You might need to select the local or iCloud contact.

Once you set "My Card", check to see if the issue is fixed.
If you still have issues.....
Let's eliminate issues in your User's folder by testing in a new User.
CREATE A NEW USER
Go to System Preferences --> Create a New User in Accounts. Switch to the New User by logging out/in or use Fast User Switching.
Add your Exchange account to Mail.
Do you still see the issue?
    If yes, then the problem is with your base files.
    If no, then the problem is in your User's folder.
Option to repair Mail in your User's folder:
Go to your User's Library folder. (if you don't know how to find, see this link.)
Scroll to Mail folder.
Select the V2 > MailData folder.
Delete any files in MailData with envelope in the name. (should be 3)
You can test Mail after deleting envelope files. When you open Mail it will re-index your files.
If you still have problems....
Go to Containers in the User's Library folder.
Delete the com.apple.mail folder.
Go to Preferences in the User's Library folder.
If you find any com.apple.mail.plist files, delete these.
Log out under the Apple in the Menu bar
Log in
Open Mail.
