Positioning Assessment
Outlook is part of how many people work. Asking them to abandon it creates resistance before a new tool has had a chance.
Triostack Mail lists Microsoft 365 among its integrations for syncing with Outlook, Calendar and Contacts. Ask us for the details of what is synced and how it is set up on your plan.
“People kept Outlook open at first. Within a month most had moved over by choice.”
