Benefits
Good to know about this tool
Creates a CSV list of mailboxes and distribution lists for import via Exchange Online PowerShell.
Because mailbox and distribution list migrations often require many objects at once, and maintaining them individually would be error-prone.
- Prepare distribution lists for all departments
- Export a mailbox list before a tenant-to-tenant migration
- Create a PowerShell import batch for new mailboxes
- Always keep the alias field unique within the tenant
- Specify distribution list members with a full SMTP address
- Test the CSV in a test environment before the PowerShell import
Frequently Asked Questions
Does this tool import directly into Exchange?
No, it only generates the CSV file. The actual import happens via PowerShell cmdlets like New-Mailbox or New-DistributionGroup.
Is my data stored anywhere?
No, everything stays in the browser and is only downloaded as a file on export.
