Can we grant permission to a Shared Mailbox which contain mail-enabled security group

Question

We have the following case inside our Office 365 tenant:-

• We have a Shared mailbox
• Inside the Shared mailbox >> we define a mail-enabled security group as a Member of the Shared mailbox.
• the mail-enabled security group contains 8 users

Now inside a SharePoint group >> we grant the Shared mailbox Read access to the SharePoint site>> but the 8 users inside the related mail-enabled security group, did not get access to the SharePoint site through the Shared mailbox.. so is our setting supported?

Thanks

Hi @john john ,

In my tests, I can reproduce your problem.

This problem is really weird. It is hard to troubleshot this issue via community, we suggest you open a service request from Microsoft 365 Admin Center for further help.

Here is a similar case for your reference:

• Users not receiving email when being added to a sharepoint site group

Thanks,
Echo Du

@john john If you want to use groups for email and collaboration, we recommend that you create an Office 365 group instead.
