After a user successfully connects their email and calendar, encountering no error messages, receiving the success message (your account is integrated!), and seeing both email and calendar boxes checked off (image below), a user’s integration should function without issue.
If a user wishes to test that the integration is working properly, sending an email gift invitation to their personal mail account is the best approach. This will allow them to confirm that the email invitation is sent from their integrated mail account as opposed to the Alyce domain.
With this working correctly, there is no reason to believe that the meeting booking feature would not work as well. If a user would like to test this, they should work with their Customer Success Manager, as accepting a gift will result in 1) the gift being always present on their dashboard and 2) a gift cost being incurred unless the CSM stops fulfillment.
