I am developing an outlook add-in which requires a single toolbar with a
single button being added to the MailEditor window. Upon debugging my project
the first time, the button is created and all is well. However, after closing
outlook and debugging again, a duplicate toolbar is added (with the button).
This continues to happen and toolbar after toolbar is added. I manually
remove the Add-In and restart Outlook and the buttons are still there, the
only way to remove them is by restarting my PC, and it just happens again.
How would I go about solving this problem?
