Microsoft 365 - Linking a service account to a NetID

You can make it more convenient to access your mail by linking your Office 365 service account to your NetID. Linking your accounts allows you switch accounts without requiring a log-out, access your service account in additional ways, and provide various management options for the NetID over the service account.

Linked Account page transition - coming June 12, 2025

The "Linked Accounts" feature is being eliminated because it is redundant. Starting June 12th, 2025, you will no longer be able to link a NetID to a service account. Instead, you will need to use the Office 365 Permissions page to assign the desired mailbox permissions. Note: Linking a NetID to a service account provided both "send as" and full mailbox permissions to that account..

Important: If you were linked to a service account prior to this change, no existing functionality will be lost.

The Linked Accounts page for service accounts will provide links to specific actions instead:

See Microsoft 365 - Manage Full Mailbox, Send As, and Send on Behalf of Permissions for more information regarding service account mailbox permissions.

Note: If you have a service account that ends in mailplus.wisc.edu, please email wmplusadmins@doit.wisc.edu for assistance with this process.

What are linked accounts?

Linking is the recommended way to provide a NetID@wisc.edu account with the ability to interact with a Service Account. Specifically, linking a Service Account to a NetID:

  • Provides Full Mailbox Permissions, which allows the NetID to interact with account data

  • Provides Send As Permissions, which allows the NetID to send messages using the Service Account email address

  • For Outlook for Windows, linking will automatically load the service account within Outlook.

  • For Outlook for Mac, the service account will need to be added as another mailbox so that it loads in Outlook.

Setting Up Linked Accounts

A NetID that has been granted access to your Office 365 service account is called a "linked NetID". If you aren't sure whether your NetID has been granted access to your service account, you can view the linked accounts for your NetID to verify.
