Hello @Christopher Cummins
Welcome to the Q&A Community!
Thank you for contacting us regarding the creation of twelve student email accounts for a one-time email exchange with a third-party product.
To maintain compliance with data protection and identity management standards, we strongly advise against creating actual student accounts for temporary use and later reassignment. This practice can lead to audit inconsistencies, data leakage, and regulatory issues.
Instead, kindly check these supported and secure alternatives:
Option 1: Plus Addressing with a Single Mailbox
This method allows you to create one mailbox and generate multiple unique email addresses using plus addressing. All messages will be delivered to the same mailbox, and you can configure rules to organize them.
Example addresses:
- ******@school.edu
- ******@school.edu
- ******@school.edu
Key points:
- Requires only one mailbox and no additional licenses.
- Plus addressing is enabled by default in Microsoft 365.
- Ideal if the third-party system accepts email addresses in the format local+tag@domain.

Option 2: Multiple Shared Mailboxes
If the vendor requires distinct email addresses but does not require individual logins, you can create twelve shared mailboxes. These mailboxes do not consume licenses and can be accessed by delegated staff members.
Key points:
- Each mailbox will have its own unique address.
- Shared mailboxes cannot be used for direct sign-in.
- After the one-time use, these mailboxes can be deleted without compliance concerns.
