I have lots of contacts in Outlook and I am looking for a way to update some contact fields so they will be more consistent. For instance, I’m looking to update the following properties;

• For some contacts I’ve entered “AVE” and for other “Avenue”. I want this to be “Avenue” for everyone.
• For some contacts I’ve included the country code in their phone number and I’d like to remove that.
• Change the email address domain of several contacts as their company changed its name and has a new domain name.

How can I achieve these changes without modifying all contacts one-by-one?
