On Super User, microsoft-accessmicrosoft-access has 13 questions while ms-accessms-access has 6. No questions have both tags.
Also, twotwo questionsquestions are tagged 'access' when one of the above would be more appropriate (accessaccess is being used for questions about, well, accessing things).
I realize this is a small enough retag that a normal user could do it, but I don't have enough rep to do it myself.
