Upload Emails from Mailbox to Vaultastic V4 Open Store

Overview

The Open Store of Vaultastic Version 4 is where you can upload data files.
These files can remain on the Open/Deep Store till you download them or copy the data to Active Store for discovery.
There are multiple ways you can upload data files to the Open/Deep Store. These methods are highlighted in the topic here.
This topic discusses the method of using LegacyFlo to upload data from mailboxes using LegacyFlo.

Prepare the SOURCE SERVER to allow access to LegacyFlo

Before using LegacyFlo to access email data from source servers using the IMAP protocol or via the mail server API, confirm the following

Prerequisites for all mail servers

The emails to be migrated are available in the mailboxes hosted on the source server. Emails that have been downloaded using the POP protocol and deleted from the server, cannot be migrated using this option.
You should have the credentials to access the mailboxes to be migrated. You should have the rights and the capability to reset the passwords on the source in order to access the mailboxes OR should be able to delegate the access.
If the source server is hosted at your own premises, you have provisioned sufficient Internet bandwidth to transfer the mailbox data.
The source email service provider should allow large emails downloaded via IMAP/API without any throttling.
Your email service provider supports IMAP or API access to mailboxes. You have configured your email server to allow IMAP or API access as mentioned in the sections below.
