You can select any one of the options to load the mailboxes.
- Load Mailboxes automatically: It automatically loads all your mailboxes present on the source server in real time.
- Load Mailboxes Using .CSV file: After successful login, if the automatic mailbox listing has failed to retrieve all the mailboxes then you can load all the mailboxes using .CSV file. If you have chosen Load Mailboxes using .CSV file, then you need to follow the below steps to load the mailboxes from the .CSV file.
