Hi Lucian,
Sharing a normal Office 365 mailbox among multiple users using a single set of credentials violates Microsoft’s licensing and security guidelines. Microsoft clearly states that licenses are assigned to individual users, and each user must have their own account. Using a single account for multiple users not only breaches licensing agreements but also presents significant security risks, such as disabling Multi-Factor Authentication (MFA).
Microsoft Documentation Reference:
- Microsoft 365 Licensing Terms: According to Microsoft’s licensing terms, licenses are per user, and credential sharing is explicitly discouraged.
- Shared Mailbox Licensing: Microsoft recommends using a shared mailbox for scenarios where multiple users need to access a mailbox, as this type of mailbox doesn’t require individual licenses.
Recommendation:
- Switch to using a proper shared mailbox setup where individual users have access permissions. This aligns with Microsoft’s licensing policy and maintains security integrity.
