HubSpot Deactivated User Contact Reassignment

Overview

When a HubSpot user is deactivated before their contacts are reassigned, those contacts become orphaned — still owned by the deactivated user but unreachable through standard owner filters. This causes workflow automation failures wherever a step sends notifications or assignments to the contact owner, resulting in "invalid user" errors across any workflow that references the owner.

This article documents the process for finding and bulk reassigning those contacts.

The Problem

Deactivating a user in HubSpot does not automatically reassign their contacts. Any active workflow that sends an internal notification or action to the contact owner will fail with an error like:

"Not sent because the user was invalid."

The compounding issue: once a user is deactivated, they no longer appear in standard contact owner filter dropdowns, making it non-obvious how to locate their records.

Observed at CAI: Jay Gardner was deactivated while still owning 3,260 contacts. Multiple active workflows were failing because they attempted to notify him as the contact owner.

Resolution Process

Step 1: Filter Contacts by Deactivated Owner

1. Navigate to Contacts in HubSpot.
2. Open the filter panel and add a filter: Contact Owner → is any of.
3. In the owner search dropdown, look for a checkbox at the bottom labeled "Show deactivated owners" (or similar — UI label may vary by HubSpot version).
4. Check that box. Deactivated users will now appear in the list.
5. Select the deactivated user (e.g., Jay Gardner) and apply the filter.

Step 2: Select All Filtered Contacts

1. With the filter applied, use the select all checkbox at the top of the contact list.
2. Confirm the full count is selected (HubSpot will indicate how many records match).

Step 3: Bulk Reassign

1. With all contacts selected, use the Actions menu → Assign.
2. Choose the new owner(s) as directed by the client.
3. Confirm the reassignment.

Note: Before executing the reassignment, confirm with the client who the new owner(s) should be. They may want contacts split across multiple reps, assigned to a generic inbox owner, or left unassigned.

Prevention

To avoid this situation in the future:

• Before deactivating a user, filter their contacts and bulk reassign first.
• Alternatively, HubSpot's user deactivation flow may prompt for reassignment — follow that prompt if available.
• Audit active workflows for any steps that send to "contact owner" and verify all referenced owners are active users.

Related Issues

Deactivated-owner contacts are a common root cause of workflow errors. If you see errors flagged under Workflows → Needs Review, check whether the failing action targets a contact owner — this is a likely culprit.
