This article dives into options that exist if portal users are not getting your invitation
So you've created a new portal user, but they're not getting the invitation email. This could be due to a variety of factors, such as spam filtering and IP whitelisting. Spam filtering is a common security measure implemented by email providers to protect users from unsolicited and potentially harmful emails. It is possible that the invitation email was mistakenly flagged as spam and filtered out of the user's inbox.
Similarly, IP whitelisting is another security measure used by organizations to limit access to their systems and networks. If the email server's IP address is not included in the whitelist, it may result in the invitation email being blocked or redirected to a spam folder.
Fortunately, System Administrators have several next steps that can help ensure the user is able to successfully log into the system. The first step is to resend the invitation email. This can be done by navigating to the Portal User Management page profile in the portal and selecting the option to resend the invite.
This will trigger a new email containing the invitation link to be sent to the user's registered email address.
If this still doesn't work, you can use the Key icon to generate a password for users.
Users will be asked to change this password upon first login.
