Naming of Exchange sender

If you have a problem with a sender-name not being spelled correctly, when you receive e-mail from an internal/external account, remember to check if you have a Mail Contact created for that e-mail address. If the mail-contact is created with a spelling mistake, Exchange will overwrite the senders name and replace it with the Mail Contact’s name. Correct the Mail Contact and it will be corrected immediately after, when you receive from that address again.
