Troubleshoot custom fields
The custom field I created is not visible.
- Custom fields are stored in the folder in which you create them. Open the folder in which you created the custom field to see if it is visible. You must recreate a custom field for each folder in which you want to use it.
- Custom fields are stored in the field set called User-defined fields in the Field Chooser and in the Show Fields dialog box. To see all the custom fields in a folder, open the folder. On the View menu, select Arrange By, then select Current View, and click Customize Current View. On the View Summary dialog box, click Fields. In the Select available fields from box, click User-defined fields in folder.
You cannot sort, group, or filter a formula field or combination field in Microsoft Outlook.
