How to add external email addresses to AWS WorkMail Group?

I can create a group on the Amazon WorkMail console and add internal users to the group. However, I do not see an option to add external email addresses with different domains.

Any tips on how to do this? Should I just create an email forwarding rule on an internal user?

Unfortunately, at present, this isn't possible (more info below). So, your proposed solution of creating an email forwarding rule is likely the best solution.

One thing to note is that you may want to set up email redirect rather than email forwarding. If you redirect, the end recipient will see the email as coming from the original sender and addressed to the original recipient, as opposed to being forwarded. In WorkMail, you'll find redirect as one of the options, alongside forwarding, when setting up the rule(s).

One additional tip for setting up the redirect/forwarding rule. There's no condition in the rules setup to just forward everything. Because of that, you'll likely want to create 2 rules. The first rule would use the condition has my name in the To box and the second rule would use the condition Does not have my name in the To box. This should have you covered for just redirecting/forwarding everything. Fortunately, you can redirect to multiple destinations, so you can probably get away with just these 2 rules even if you have multiple final destinations.

Additional info about not being able to add external addresses to groups:

An AWS team member has stated that this isn't currently supported in this AWS forum post from 2017:

Indeed, it not possible to add an external email address to a group. I will forward this feature request to the service team.

A possible workaround is to create a redirect rule that redirect emails sent to this group to the external users.

As of today, you still get the following message when adding members to a group (console screenshot):

You can only add users and groups that are enabled for access to Amazon WorkMail.

Bulk addition of email addresses to a rule

Unfortunately, there don't currently appear to be any APIs to create inbox rules programmatically. However, you can copy-paste a large number of emails into a rule.

First, you'll want to export the set of email addresses you have into e.g. a CSV file.

Then, you'll want to append a ; to each email address. The reason for this is that the character is recognized as a separator. If we don't use it, the email rule will interpret the entire pasted text as a single email address. As an example, in Google Sheets, this can be done with CONCATENATE. E.g. =concatenate(A1,";"). Here's a screenshot: Setting up an email list

Next, open the email rule, copy the email addresses from the spreadsheet, paste them into the recipients box, and click the To button. In this case, it's 100 emails, so it takes a little bit of time to load: enter image description here

Once it finishes loading, you'll see checkboxes next to the email addresses, like when you add single email addresses manually. enter image description here

Make sure to click Ok on the recipients dialog, then click Ok on the rule dialog, and finally click Save changes on the Email Rules Settings panel to ensure everything gets saved.
