Zoho Campaigns to CRM - Opt Out not syncing

Zoho Campaigns to CRM - Opt Out not syncing

Hi!

I have run a campaign from Zoho Campaigns creating the initial list from a sync from Zoho CRM.

The contacts who have responded to the canmpiagn and unsubscribed (and are now marked as Do Not Mail within Zoho Campaigns) are not being updated back to Zoho CRM.  The Email Opt Out flag remains blank in Zoho CRM.

The campaign status is being pushed back to the Contact record in Zoho CRM and I can see this in the contact record.  The campaign status field shows the history of status changes.

I origionally created the sync as a 1 off sync and have now updated it to a daily sync - but still the Zoho contact record is not being updated with the Email Opt Out flag.

Please help as I have follow up campaigns that I need to send and am stuck.

Thanks

Tim
