I recently created a forum where I sent my friend email invites. He has more than 1 email registered to the same domain, named as follows:
- email+1@xyz.com
- email+2@xyz
- email+3@xyz
.
.
. - email+11@xyz.com
When I sent him the invites as bulk invite, he was only able to register from the first email and Discourse showed the following error when he tried signing up with the last email on this list:
Validation failed: Primary email has already been taken.
TIA for any help resolving this issue!
