About these listed integrations
What "listed" means
Each tool below lists Microsoft 365 among its integrations in our data. Our data does not record whether a connection is built by the vendor or runs through a third-party connector, so open the setup link or the vendor's docs before you commit. Automation hubs such as Zapier, Make and n8n are left out, since they connect to almost everything.
Before you turn it on
Confirm sync direction (one-way or two-way), check which Microsoft 365 plan or workspace permissions are required, and run a test record through before connecting production data.
