Information:

Environment

  • Dynatrace Classic Portal
  • Alerting

 

Symptoms

I am trying to add one email address to the Recipients list of an alert destination, but I got "One or more email addresses in your list is invalid." after I clicked Submit button.

Solution

The email address to be added contains a symbol of apostrophe ('). In the Dynatrace Classic Portal, this character is not supported in the alert destination recipients list. The workaround is to create an email alias which includes that email address, and add the email alias to the recipients list.

Note: This issue does not occur in the Dynatrace Portal.

Root Cause

The symbol of apostrophe (') is not supported in the alert destination recipients list.
