Why Connect Microsoft 365 to Trello?

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

Client engagement details in Microsoft 365 and time-tracking data in Trello do not align, making billing inaccurate

Manually copying data between Microsoft 365 and Trello wastes hours every week that could be spent on revenue-generating work

No single source of truth when contacts live in two disconnected tools, so staff second-guess which system has the correct information

Microsoft 365 uses a REST API while Trello uses REST + Webhook, requiring careful middleware to translate data formats between the two platforms

Reporting across Microsoft 365 and Trello requires painful manual exports and spreadsheet merges
