How to Auto Assign a Color Category to New Appointments via Outlook VBA

Many users prefer to manage Outlook appointments by “Color Category” . So they hope that Outlook can auto categorize new appointments. This article will introduce how to realize it.

The article “How to Auto Categorize Appointments in Outlook Calendar” introduces a workaround. It uses Conditional Formatting to color code the appointments. Actually it just assigns a color to the item, not uses color category. Besides, Conditional Formatting relies on view settings. That is to say, if you create a conditional formatting rule in the current view, in another view, the rule will be invalid. So it is a get it.

Beware of Malicious Macros in Outlook

There are a lot of dangerous macros. So we should only use digitally signed macros. And, nowadays, viruses in emails become more and more common. They are usually disguised as innocuous objects in the emails. Once we open, click or download them, our Outlook will get infected and then data will be corrupt. It is hard to recover damaged Outlook. So at this point, we have no choice but to use third party repair tools.
