Resolution

  1. Hover over your initials at the bottom of the left-hand navigation menu and click Personal Settings.
  2. Find and click the affected mailbox.
  3. Scroll to the bottom of the page and click Show advanced settings.
  4. Under the header Send Settings, uncheck the box labeled Require mailbox to be recently synced before sending.
  5. Go back to your Outbox and try the mailings that failed to send.

Cause

This occurs when your mailbox hasn't been recently synced with Outreach. You'll also want to confirm your mailbox is currently syncing with Outreach in the same mailbox settings page. If not, you'll want to enable syncing or reconnect your mailbox and try syncing again. Please refer to our guide on How to Reconnect and Remove mailboxes & Calendars for more details.
