Microsoft 365 add-ins and Third party applications

IT Services do not currently support any Microsoft 365 add-ins or third-party applications.

Users should be aware that each add-in or application is a service provided not by Microsoft but by a separate third-party company that the University does not have a current contract with.

Enabling the add-in may involve giving the third-party company access to your Trinity College email and Calendar data and in some instances allowing the data to be transferred to the Third-party company.

This may cause data security and privacy issues and may not be GDPR compliant.
