FindFolder Operation

Topic Last Modified: 2008-07-08

The FindFolder operation uses Exchange Web Services to find subfolders of an identified folder and returns a set of properties that describe the set of subfolders.

Remarks

FindFolder returns only the first 512 bytes of any streamable property. For Unicode, it returns the first 255 characters by using a null-terminated Unicode string.

Deep traversal queries are not allowed on public folders.

Restrictions are permitted and should only use the folder properties, not the item properties. Sorting functionality is not available for FindFolder responses. Grouped queries are not available for FindFolder queries.

Note The FindFolder operation is also used to find managed folders.
