In the same screen, Select Email as category under Workload Selection. EML file only stores the emails.
You will now come to the Source screen where you have to select the folder path where the Emails, Contacts, Calendars and Documents are stored.
You have to put these files in their respective folders (created with the name of target O365 or Microsoft 365 email IDs) as described below:
Create a folder in root drive, like:
Go to the drive where you have stored your data.
Within the drive make a folder named eml.
Each user should have their own separate folder.
For Emails:
a separate Email folder should be made
This folder can contain further subfolders as well.
Which inturn contain their respective *.eml files.
In the end the folder structure should resemble the following:
D:/Import/[email protected]/Email/SubFolder/ (put all Email (.eml) files of user1)
D:/Import/[email protected]/Email/SubFolder/ (put all Email (.eml) files of user2)
D:/Import/[email protected]/Email/SubFolder/ (put all Email (.eml) files of user3)
etc...
If you are importing contacts, make a separate folder Contact:
Within which the following structure should exist
D:/Import/[email protected]/Contact/ (put all Contact (.vcf) files of user1)
D:/Import/[email protected]/Contact/ (put all Contact (.vcf) files of user2)
D:/Import/[email protected]/Contact/ (put all Contact (.vcf) files of user3)
etc...
If you are importing calendars, make a separate folder Calendar:
Within which the following structure should exist
D:/Import/[email protected]/Calendar/ (put all Calendar (.ics) files of user1)
D:/Import/[email protected]/Calendar/ (put all Calendar (.ics) files of user2)
D:/Import/[email protected]/Calendar/ (put all Calendar (.ics) files of user3)
etc...
If you are importing documents, make a separate folder Document:

etc...
And then select the folder "D:/Import/" into our tool as "Import Folder Path".

- Summary Report - The summary report downloads a single report displaying all the user accounts along with import details of emails, contacts, calendars.
- Detailed Report - The detailed report downloads individual reports of all/selected G Suite user accounts with their import details.
The tool provides two options for downloading the reports:
Summary Report: The summary report will be a single .csv file containing import reports of all the selected users.
Detailed Report: Here, you get the option to save the detailed import report of the mailboxes you want to. Select the mailbox and Click on Download button.
Choose the destination location where you want to save the Detailed Report.
