Help Desk, Office Add-in Support
Office Add-ins, formerly called Apps for Office, are third-party, self-managed, extra extensions and applications that can be installed into the Microsoft 365 programs to provide additional features.
Technology Services deploys a few Add-ins, such as Proofpoint for Outlook, and other units on campus may configure more for their own users. The Help Desk can assist users with installing an Add-in, but cannot provide support for using or configuring specific 3rd-party Add-ins.
Microsoft provides some information about installing and managing Add-ins in their support article: View, manage, and install add-ins for Excel, PowerPoint, and Word
Microsoft also provides some information about using Add-ins in this support article: Start using your Office Add-in
