Zoho CRM Slow Sending Email with Outlook 365 Integration

We have recently added the Outlook 365 Integration to our Zoho CRM system, however once we have written the email when we click on 'Send', the send process takes a long time. 

We are not adding any attachments, just plain text with a couple of merge fields.

Is there anything that can be done to make this faster?
