Before you add your Outlook contacts:
It is recommended you move all contacts you wish to import from your Exchange Contacts into Dynamics CRM into a single folder.
For best results, make sure your Outlook contact data is as complete and accurate as possible. Fill in any missing info and verify that people’s names are spelled correctly.
Because you will have the opportunity to “map” the company names in your Outlook contact list to an account name in Microsoft Dynamics 365, make sure the accounts have the same spelling in both applications.
