ATP licenses for shared mailboxes?
When are licenses required for Shared Mailboxes? Licenses are required for the shared mailbox for the following: Increasing the shared mailbox size limit to 100GB requires Exchange Plan 2 (or Plan 1 + Exchange Online Archiving [EOA]). Enabling E3/EXO P2 capabilities (for example, applying a basic mail retention policy) Exchange Plan 2 (or Plan 1 + EOA). Enabling E5 capabilities (for example, automatic retention or classification, Microsoft Defender for Office 365 (previously O365 ATP)) requires a license that includes the rights to those capabilities (for example, E5 Compliance, E5 Information Protection & Governance, E5 Security).
PascalDBX It's a bit confusing.
Let's say Bob leaves the company. Prior to leaving, he had a 365 business standard license + Defender license. We convert his mailbox to a shared mailbox and give access to it to another user. Since it's been converted to shared, we don't need to apply the 365 Business Standard license to his user account but do we need to leave the defender license?
I'm asking because if you create a fresh shared mailbox, there are no options to apply a license
My text is the Microsoft official license rules text.
If a mailbox shared or not - use for example Defender ATP - customer need to pay for the license.
Ground rule:
If you get benefit of the service - you need to pay for the licence.
PascalDBX How do you apply it to a shared mailbox that wasn't converted from a user mailbox? There are no license options.
PS83Tech You don't and can't apply it, you just need it purchased.
