To generate a keywords header field, clients must set the value of this property to the desired values. This property has multiple strings; each category should be mapped to a single keyword.

Multipurpose Internet Mail Extensions (MIME) writers should copy each sub-value of this property to a separate keyword in the Keywords header field, with a comma (U+002C) and space (U+0020) separating each keyword. MIME writers may drop this property instead of copying it to the keywords header field, in order to avoid conflict among different sets of categories in different organizations.
