For better or worse, I am fully entrenched in Outlook 365. Thanks to the excellent, and recently updated, Outlook GTD Setup Guide, my system is working well for me. My struggle of late is tracking items related to Contacts, such as Tasks, conversation history, etc... Outlook used to have a feature that linked Tasks, Calendar and Email to a Contact, but it disappeared starting with Outlook 2016. Over the last couple of weeks, I have been fiddling around with Outlook Customer Manager (OCM) that is part of the software package available with a Business Premium license. OCM is a very basic CRM within Outlook that should give me back some of the ability to build a timeline of Tasks, Email, etc.. for a Contact. The issue now is that OCM does not play nice with the Task folder system in GTD. When a Task is moved from the Task folder, it no longer associates with the Contact. Two questions, please: Is anyone having success with OCM within Outlook setup for GTD? Any recommendations for better tracking activity linked to an Outlook Contact? I have tried stand alone CRMs that advertise Outlook integration and have not been happy with the result.
