After installing WebMail you get the following error:
800A01A8 VBScript Object Required
from either lang_include.inc or include.inc
Configure IIS to run WebMail as an application so that it will use the Global.asa file.
Open Internet Services Manager, expand the local computer, expand WebSites and expand Default Web Site. Right click the WebMail virtual folder and select properties. Select the directory or home directory tab. On the bottom half of the window you now see there should be an application settings section. If this directory is not already set as an application then you need to make it one by clicking â€œcreateâ€ and then clicking OK to save the settings.
