How can I first check to see if Outlook is already open? (I don't want to open multiple instances)

Hello djvice,

You can use GetObject to test if an instance of a object has been created.

Note: GetObject will not detect instances of an object created in VBA code. If you start Outlook from VBA then GetObject will always return an error.

Sincerely,
