Outlook Integration - Syncing Emails

Outlook Integration - Syncing Emails

We have 3 Zoho CRM users within our company with the potential for more being added later this year. We each have access to all contacts, potentials, etc - we share everything except activities/tasks. 

Each of us are using the Outlook 2016 integrated plugin. When I receive an email from a contact, often times either one of my colleagues will receive the same email. 

When this happens, it is likely that we're both going to add the email to a contact unknowing of the fact that the other is doing the same thing. This creates duplicate email attachments of the same email to the contact. 

Is there any way to eliminate this redundancy?
