Standard Microsoft 365 Installations for Most Employees

All new PCs and Macs that are set up by ITD staff come pre-loaded with the Microsoft 365 Suite, including Microsoft Teams

Employees may choose to install the Microsoft 365 applications on their Brookhaven Lab mobile phones or tablets as well as on their personally-owned devices. ITD permits "Bring Your Own Device" (BYOD), so long as they are secure with up to date operating systems and patches. The Lab's Microsoft 365 licensing allows for installations on five PCs or Macs, five mobile phones and five tablets, concurrently. If you need DUO for the installation please review the DUO section.

Teams and Microsoft 365 are part of the collection of applications available to all Brookhaven Lab users on the Ivanti/LANDesk Portal Manager. Please contact ITD at, Ext 5522, or (631) 344-5522 for help installing Microsoft 365 and Microsoft Teams.
