When I exported my old phones contacts from lookout express, and imported them in to Outlook (the different phone software picks a different default outlook version), they all came imported with an email address of "[No email address found]". My old phone didn't have email addresses for people, so I thought it was no biggy, but my new one does, and it irritated me. An hour or so of trying to write a VB macro in Outlook resulted in me combining the 'ResetBirthday2' [1] macro from Microsoft with the right bits from this [2] one to get a macro that loops through all my imported Outlook contacts and replaces any 'no email found' with blanks.
I'm glad I don't have to do VB for a living.
