Install Zoom for Outlook Add-in from New Outlook’s built-in app store—not the legacy Zoom desktop plug-in—and then authenticate with the Microsoft account that owns the Outlook calendar.
Install and connect the correct add-in
- In New Outlook for Windows, select More apps → Add apps.
- Search for Zoom for Outlook.
- Select the Zoom add-in and choose Add. Microsoft identifies this as the web-add-in replacement for the old Zoom Outlook plug-in.^1^
- Open Calendar, create a new event, and select Zoom from the ribbon. If it is not visible, open Apps to find it.^2^
- Sign in to Zoom, then complete the Microsoft authorization using the same Microsoft account shown as the event’s calendar owner.
New Outlook does not support the older COM/VSTO Zoom desktop plug-in; it requires the web-based Outlook add-in.^3^
If Microsoft login still stops
First open Outlook on the web and sign in with the same address. This distinguishes an Outlook-account problem from a Zoom authorization problem.
- If Microsoft sign-in fails there too: recover or correct the Microsoft account before reconnecting Zoom.
- If Microsoft sign-in works there: return to the Zoom add-in, open its settings, sign out of Zoom, and sign back in to create a fresh session. Keep the same Zoom account signed in within both the add-in and Zoom’s web portal, because using different Zoom accounts can replace the active session.^4^
- If the message says a personal account cannot be used: the connection is attempting a work-or-school Microsoft 365 authentication route. Use the Outlook.com/personal-account option if Zoom presents one rather than the organizational Microsoft 365 option.
- If this is a Gmail, Yahoo, or another non-Microsoft mailbox added to New Outlook: Outlook add-ins are not supported for those accounts. The supported mailbox types are Outlook.com personal accounts and Microsoft 365 business mailboxes.^3^
- If Add apps or Zoom is blocked: for an employer or school account, the Microsoft 365 administrator may have restricted Marketplace add-ins. Ask the administrator to allow or deploy Zoom for Outlook Add-in.^1^
Until login is resolved, schedule the meeting directly in Zoom, copy its invitation link, and paste it into an Outlook calendar event.
