Invite user not working in cloud?

[Pieter Kuppens]

I'm trying to invite a user to Jira Cloud.

Even though Administration panel says Invited/Invitation Pending, the user did not get any mail.

Also not in spam, etc.

What could possibly be wrong? How can I solve or circumvent?

@Hello @Pieter Kuppens 

Verify on site access which email address domains are allowed to join.

This could have been at least part of the solution, but we also may have overlooked some mail filters from the user.

It now seems to be working, though not as fast and flawless as seen with different users.
