Request for Email Activity Report with Internal/External Breakdown

Aran Billen 761 Reputation points

Hi everyone,

Is it possible to generate a report that shows the number of emails sent and received by each user, with a breakdown of internal and external emails?

I understand that we can find some basic metrics in the admin center under Reports > Usage > Exchange > Email activity. However, this does not separate the count of internal and external emails.

Does anyone have any suggestions or know of a way to achieve this?

Thank you!

    Hi @Aran Billen ,

    Thank you for posting to Microsoft Community.

    As you mentioned, you could get the email activity report which includes the total sent count of users via Microsoft 365 Admin Center.

    However, I am afraid there's no such a feature to select internal and external emails report separately at present.

    You could run the following command to get the number of external/internal emails sent in the last 30 days by specific users:

    Get-MessageTrace -RecipientAddress <user_email_address> -StartDate (Get-Date).AddDays(-30) -EndDate (Get-Date) | Where-Object {$_.SourceContext -notlike “* 8”} | Select-Object RecipientAddress, SenderAddress | Group-Object RecipientAddress | Select-Object Name, Count

    Then please kindly replace the “notlike” in the command to “like” to check the internal emails.

    You can repeat the command for each user and combine the results to get a report of the number of external/internal emails sent by all the users you are interested in.

    Also, I've just tried submitting a suggestion via the dedicated feedback portal for Exchange Online. I'll leave the link below so that you or other community members can also add vote or comment there. Let's hope this kind of report can be added in the future.

    If my answer is any helpful to you, please mark it as the answer so that other users can refer to it. Thank you for your support and understanding.
