My original answer didn't seem to make it past Mod approval. Perhaps because of the included Outlook View Formula in a Code Block. So here it is again as all plain text.
View -> View Settings -> [Columns] -> [New Column]
Name: RecipientCount
Type: Formula
Formula:
"To: " & IIf(Len([To]),Len([To])-Len(Replace([To],";",""))+1,0) & ", CC: " & IIf(Len([CC]),Len([CC])-Len(Replace([CC],";",""))+1,0) & ", BCC: " & IIf(Len([BCC]),Len([BCC])-Len(Replace([BCC],";",""))+1,0)
The idea is that multiple Recipients in the [To], [CC], and [BCC] fields are semi-colon separated, so (if the field is not empty) you can calculate the difference in the field length with/without semi-colons to get the count.
