I am trying to set a primary smtp address to a user based on input during creation.
If someone set a specific email in form, this is stored in customAttributeText3 and set to mailbox later:
Based on email type its SMTP (lowercase letters). From my knowledge capital SMTP address is the primary one.
The action after saving shows smtp (upper case letters) and the email address is also only added as alias and not set as primary.
How can I set a specifc email address as primary?
Do I need to run a PS command to set it?
