Why Connect Microsoft 365 to Todoist?

Task updates in Microsoft 365 are invisible to the team using Todoist, leading to duplicated effort and missed deadlines

Transaction data in Microsoft 365 requires manual verification against Todoist, increasing audit risk

Todoist adds complexity: limited reporting means managers cannot track team velocity, completion rates, or project progress without manual analysis
