Why does it take so long for my initial backup to be completed?

The time to complete the initial archive can depend on any of the following reasons:

1. Number of emails added
2. Size of the mailbox
   1. The greater the size of the mailbox, the longer it takes for the initial archive to be completed
3. Number and size of attachments
   1. Since our archive service lets you navigate your attachments and files separately using the file manager, the more the number of attachments in the email, the longer it takes for the initial archive to be completed
4. Limitations imposed by the Microsoft Office365 API
5. Bandwidth restriction on the mail server side
