Why does this have to be a macro?
Press the Categorize button or use the keyboard shortcut for your localized
version of Outlook.

Thanks for your response, but Outlook does make reference to macros. In any
case, I found the following code in another thread that enables me to select
a bunch of emails in my Inbox and move them to the folder called “RcvBkt”,
which is a folder located within my Inbox. I would like to assign a
hard-coded category to a number of selected emails in my inbox. I imagine the
code is very similar, except the move statement in the routine below would
change to something like the statement below. However, the closest thing I’ve
come up with is "objItem.Categories", but it’s not an action like move is so
it doesn’t work. Any suggestions?

               objItem.SetCategory “PERSONAL”

Sub MoveIt()
On Error Resume Next

   Dim objFolder As Outlook.MAPIFolder, objInbox As Outlook.MAPIFolder
   Dim objNS As Outlook.NameSpace, objItem As Outlook.MailItem

   Set objNS = Application.GetNamespace("MAPI")
   Set objInbox = objNS.GetDefaultFolder(olFolderInbox)
   Set objFolder = objInbox.Folders("RcvBkt")

   If Application.ActiveExplorer.Selection.Count = 0 Then
       'Require that this procedure be called only when a message is selected
       Exit Sub
   End If
   
   For Each objItem In Application.ActiveExplorer.Selection
       If objFolder.DefaultItemType = olMailItem Then
           If objItem.Class = olMail Then
               objItem.Move objFolder
           End If
       End If
   Next
   
   Set objItem = Nothing
   Set objFolder = Nothing
   Set objInbox = Nothing
   Set objNS = Nothing
End Sub
