Licensing for dedicated Admin accounts?

[Franck Marteaux]

hi there,

in our Windows AD we are using dedicated ADM accounts for Admin tasks.

How are these accounts licensed for O365 and EMS functionality?
These accounts do not need Office 365 PP, or a mailbox, however they need MFA, PAM.

Do Exchange Online Admins need an Exchange Online License and SPO Admins an SPO License.

We would like to avoid to license for Admin to licenses, one for their user account and one for their admin account.

What is the best practice, preferred model or recommendation here?

Thanks,
Franck

Almost all admin functionality across O365 is available without the need to assign a license. Some exceptions exist for eDiscovery and such, but overall no license is needed. MFA is included at no cost for admin accounts, but if you use some of the more advanced features such as Azure AD PIM, you will need the  corresponding license. Same goes for Office 365 PAM, some of the features around advanced compliance, etc.
