MilkSync synchronizes all tasks in your Tasks folder, in your main email account in your Outlook profile. It may be clearer to list the items that MilkSync doesn't synchronize:

• MilkSync doesn't synchronize tasks in secondary accounts or Outlook data files, e.g. Personal Folders added to an Exchange account or secondary email accounts added to your profile.
• MilkSync doesn't synchronize tasks in secondary task folders, e.g. subfolders of your Tasks folders or other task folders added to your account or profile.

Note: MilkSync is not designed to synchronize with multiple Outlook profiles.
