Bookshelf v7.8: Factors That Determine To Do Record Synchronization

The following factors determine whether or not a to do record is synchronized:

The synchronization level that the administrator sets (Full Sync, Export Only, or None).
The value of the following configuration parameters, which the administrator also sets:
- ExtractStartDate (in MM/DD/YYYY format)
- ExtractStartDateFormat
  If a to do item has a Due date that is earlier than the value of the ExtractStartDate parameter, that item is not synchronized.
  
  For additional information on setting the extract start date, see Setting Initial Extract Start Dates for Users.
Whether or not the administrator has enabled the Full Sync Opt-in feature or the Ignore private records feature for Microsoft Outlook task records. For information on these features, see About Using the Opt-in Feature and About the Ignore Private Records Feature.
The value of the Display In field for each individual to do record. (SSSE synchronizes to do records for which the value of the Display In field is To Do and Activities.)
