Catalina Mail requires a rebuild in order to retrieve new emails
When using mail with an exchange server on a new Mac running Catalina 10.15.2 and mail version 13, emails are not retrieved unless I rebuild.
The Get Mail button does not work and neither does changing "Check for new messages" settings from automatic to every minute.
I have 3 other email accounts which all work correctly.
Suggestions?
Mac mini 2018 or later
