Outlook to CRM sync issue with plugin- CRM 365 v 8.2.0 on premise

Hi,

Am trying to synch appointments from outlook calendar to CRM . I have all the right privilges to sync to CRM, but couple of users are facing this synch issue and error seems unique.

 : "Failed to sync item to CRM server  Not enough privilege to access the Microsoft Dynamics CRM object or perform the requested operation . The current Organizationid '2###' does not match with userOrTeam's organization id '1####'.    

While the first part says about privileges, there are other users with same role are able to sync perfectly fine. Any help regarding this would greatly be appreciated. 

Thanks,

kP
