Hi,
When we invite a guest user from another domain, he can use Business central if we assign a licence.
But, there is a lot of limitation.
for exemple, with the new Mail capabilty extension , Choose Current user option.
the email adress of this kind of user is : guestuser_guestdomain.com#EXT#@mydomain.com
And so when trying to send email ( quote or invoice ), there is an error :
Ressource could not be discovered

It's a big limitation.
anybody already had this problem and found a solution ?
thank you
