Allow use of new top level domains for forwarding
We cannot forward a user's email to another email address on any of our domains from the admin centre as they end in .academy which Microsoft doesn't recognise as valid. The save changes button never becomes active and we just have the message under the box saying to enter a valid email address. If we put a dot and any two letters on the end the system is suddenly happy and will let us save even though that isn't a valid email making this check utterly pointless. Even more ridiculous is that the user themselves can set up a forward to a .academy domain in their own inbox which will then show up when we look at their email forwarding centrally so the validation on these two areas which populate each other is not the same.
I have been given a workaround today by support which involves adding the address we want to forward to as a contact and then setting up a mail flow rule however we would like to be able to use the straightforward functionality which exists to centrally forward emails on out domains which are valid. Please either tweak the validation to accept .academy as a valid domain ending or, even better, to prevent this happening with other domains that don't fall within the list accepted as valid, change it so that if you enter an email address to forward to that Office doesn't think is valid it lets you save it anyway. There could be a message that simply says 'This doesn't seem valid please check you've entered it correctly' if you really feel there needs to be a check but since currently it's possible to save forwarding to non existent addresses but not to valid ones then there doesn't seem a need to check at all. Just let us enter what we want. If it doesn't forward we'll find out and check the address we entered.
Can you please confirm where the admin is trying to add forwarding for the mailbox? Is it the Admin Portal or Exchange Admin Center?

i ran into this and was able to get it work by going back to the old admin portal and putting the forward rule in place there. worked for a .coffee domain. Seems like new admin portal doesn't allow but old one does.

As a .computer domain owner I run into issues like this all the time.
Email address validation needs to be done correctly or not at all. Microsoft should know better.
it's within the admin center after signing into office.com and clicking admin. Then choosing a user and clicking the mail tab in the pop up window then under email forwarding clicking 'manage email forwarding' after ticking the box to forward all emails we can enter an address for forwarding but there is a validation check on this field for no reason I can see which does not recognise many valid email domains. In my case anything ending .academy and as Bjorn has commented below .software is not recognised either. I'm sure there are more.
I know there is a workaround by setting up forwarding rules in mail flow within the exchange admin center but this is not as simple as the straightforward functionality that is there for those with acceptable domains and requires and extra step of adding the address you want to forward to into the central contacts. An individual user can also forward their own emails to .academy domains and that forwarding then shows up under the manage email forwarding in the admin center which makes it even more bizarre that we can't set it there in the first place.
Since new domains are always going to be created with all sorts of different endings then surely the validation on this field to judge what is a 'valid email address' could be dropped
