Email Notification or Standard Owner Change Notification Not Received

Users affected by this will need to ensure their email address has been verified (or in some cases will need to reverify their email address). Verification can take place by having an administrator:

• Reset the password of the affected user(s)
• or, change the email address of the affected user(s), save, and then change the email address back to the original value. This should trigger a verification of email change.

Once the email has been verified for the user(s), standard notifications and email alerts should function normally again.
