PidTagLastModificationTime Canonical Property
This content is outdated and is no longer being maintained. It is provided as a courtesy for individuals who are still using these technologies. This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.
Contains the date and time when the object or subobject was last modified.
This property is initially set to the same value as the PR_CREATION_TIME (PidTagCreationTime) property. Attachment subobjects can update it as necessary by copying the last modification time maintained by the native file system. A client application can set this property until the first call to the IMAPIProp::SaveChanges method. From then on the provider should update PR_LAST_MODIFICATION_TIME during every IMAPIProp::SaveChanges call.
