E1 F3 and EOP1 License

Question

The environment has shared mailboxes without licenses but the users are able login with their firstname.lastname@ssss .com. The question comes down to the license's that are needed and the ones that are redundant. It seems if the user has an E1 license assigned they would not need an EOP1 or and F3 license. Could someone add more clarification on this subject.

Hi @Santelo

Shared mailboxes do not need licenses, please check the user permission for the shard mailboxes

Get-Mailbox -RecipientTypeDetails SharedMailbox -ResultSize:Unlimited | Get-MailboxPermission |Select-Object Identity,User,AccessRights | Where-Object {($_.user -ne 'NT AUTHORITY\SELF')} | Export-Csv C:\Temp\sharedfolders.csv -NoTypeInformation  

In addtion, if you use any edition of the Microsoft Office 365 productivity suite that includes Exchange Online (such as Office 365 E1, Office 365 E3, and Office 365 E5), you are protected by the Exchange Online Protection (EOP) by Microsoft.

And M/O365 F-SKU licenses may only be assigned to users without a Dedicated Device. A Dedicated Device is a computing device user for work with a 10.1” screen or larger, use by the user more than 60% of the users total work time during any 90 day period.
These are intended for Frontline workers, shared computer users, etc, etc. not for office users as an alternative to the full skus.
