Hi @Jera Anderson ,
Welcome to our forum.
I understand you would like to find a field that support binary data in your Outlook contact page, is it right?
If so, have you tried to create a custom contact form? According to my research and test, I haven't found a dedicated binary field in field chooser of a contact form, and we may just could add the int field or yes/no field in the form, if that's your case, as a workaround, we could try to switch your data type and add the yes/no field to help you search and sort by this value.
