how to late bind various applications in outlook - vba

Question

I have a complex vba macro that uses the following references. I don't know how to late bind all of these properly to the different objects I use. How can I research what is the proper late binding convention?
Outlook 16.0
Word 16.0
Regular Expressions 5.5
For example, I am declaring the following variables in my macro using early binding, how can I find the equivalent late binding convention?
dim myNameSpace as outlook.namespace --> set myNameSpace = Application.GetNamespace("MAPI")
dim myInbox as outlook.folder --> set myInbox = myNameSpace.Folders("name of folder")
dim myItems as outlook.items --> set myItems = myInbox.Items
dim wrdDoc as word.document
dim regExp as new RegExp --> regExp.Pattern = "pattern"
Any help or guidance would be appreciated!
thank you!

The late binding makes sense when you automate Outlook from other Office applications and don't want to keep a reference to the object library.
When we use late binding, we don't have to add reference for the VBA project. In that case you should declare all your Outlook-specific objects as Object:
dim myNameSpace as Object
set myNameSpace = OutlookApplication.GetNamespace("MAPI")
Use the CreateObject method to create a new application instance:
Set olApp = CreateObject("Outlook.Application")
This will make each computer create the Outlook Application object from the Outlook library that is installed on it. It avoids you to set an explicit reference to Outlook object library in any Office application or solution that you will distribute (remove that reference from the project before distributing it).
