In the tree on the left, open English, then open Office and Desktop
Applications. In the Office and Desktop Applications
subcategory, find and open the Outlook subcategory. Find a group there
for your question.
As your problem seems to be rather urgent, you can significantly raise
the possibility of getting helpful answers by askins this question in
a group which deals with your specific email software, instead of a
group which discusses the Microsoft .NET software development
technology.
