The problem is that, by default, the name used in the Azure Active Directory is “Default Directory” which seems a little confusing, especially if you have access to multiple directories…
A CRON expression is a string consisting of six or seven subexpressions (fields), separated by white space, that describe individual details of the schedule. A very useful tool that enables users to schedule tasks to run periodically at a specified date/time in the future, thus allowing the automation of a lot of tasks and processes that otherwise would require human…
