Victor Beekman wanted to share another macro with our visitors. This is similar to our macros that search for all messages from a contact or sender but instead of doing an "in-place" search, it opens a new window with the results. The reading pane is turned off, the navigation pane is supposed to be turned off (it's left enable at times), while the To-Do Bar can't turned off.

Sub FindContactActivities()

How to Use Macros

First: You will need macro security set to low during testing.

To check your macro security in Outlook 2010 and above, go to File, Options, Trust Center and open Trust Center Settings, and change the Macro Settings. In Outlook 2007 and older, it’s at Tools, Macro Security.

After you test the macro and see that it works, you can either leave macro security set to low or sign the macro.

Open the VBA Editor by pressing Alt+F11 on your keyboard.

To put the code in a module:

1. Right click on Project1 and choose Insert > Module
2. Copy and paste the macro into the new module.
