Why some contacts selected in bulk are not updated

After using Bulk updates to modify multiple contacts, sometimes the number of contacts updated differs from the number of contacts selected, and you get the following notification:

This happens in the following scenarios.

• When changing the date of a Next Action:
  • Only contacts with an existing Next Action that is assigned to the user performing the update will be updated.
  • Contacts with Next Actions assigned to other team members will not be updated.

• If Complete Actions is selected: Contacts without Next Action will not be updated.
• If Close sales cycle is selected: Contacts with closed sales cycles will not be updated.
• If Close sales cycle with Closing Comment is selected: Contacts with closed sales cycles will not be updated.
• If Delete Actions is selected: Contacts without actions or with closed sales cycles will not be updated.

• If the selected Status label is already assigned to the selected contacts: The contact's Status label will not be updated.

  E.g., Jane Doe has the Status label Lead already assigned and is selected in bulk to be updated to a Lead Status label, her Status label will not be updated.

• If the selected Tag is already assigned to the selected contacts: The Tag will not be applied.

  E.g., Jane Doe has the Tag VIP already assigned and is selected in bulk to be updated with a VIP Tag, the Tag will not be applied to her.

• If the selected Owner is already assigned to the selected contacts: The contact owner will not be updated.

• If the selected Lead source is already assigned to the selected contacts: The contact's Lead Source will not be updated.

  E.g. Jane Doe has the Lead source Referral already assigned and is selected in bulk to be updated to a Referral Lead source, her Lead source will not be updated.
