Q: How does Microsoft Office Outlook 2007’s business card Contacts feature work?

A: Starting with Microsoft Office Outlook 2003, users can upload digital images and include them as part of individual contacts. You’d typically use a picture of the person represented by the contact information, although you can also use company logos, caricatures, or other graphics. Outlook allows files with the extensions .bmp, .emf, .ico, .icon, .jpg, .jpeg, .gif, .tif, .tiff, .wmf, and .png. If you try to upload files with another extension, including files whose original extension you’ve renamed to be one of these extensions, you’ll receive an error message. Outlook 2007 on Windows Vista returns the error message “Out of memory or system resources. Close some windows or programs and try again.” Outlook 2003 on Windows XP SP2 returns the error message “Could not complete the operation. One or more parameter values is invalid.” Active Directory (AD) on Windows Server 2003 and Windows 2000 Server doesn’t natively allow for an image as a user attribute. However, administrators can use a custom attribute to hold a URL pointing to an intranet or network share with image files. . . .
