WebMail Pro ASP.NET documentation

I see "Server Error in '/webmail/AdminPanel' Application" on attempt to log in AdminPanel. How to resolve?

You should remove ending slash in the path specified in your WebMail virtual directory properties:

Just remove the slash and press OK button. This issue seems to be a bug of IIS.
