Exchange Online PowerShell Migration Tools
This is a collection of useful commands and scripts to aid in Exchange Online tenant migrations.
Before running these commands, install and import the Exchange Online PowerShell module and connect:
Install-Module ExchangeOnlineManagement
Import-Module ExchangeOnlineManagement
Connect-ExchangeOnline
Get email aliases
Use this command to get a list of aliases for all mailboxes. Optionally specify a mailbox: Get-Mailbox 'bsmith@contoso.com' | ...
Get-Mailbox | select DisplayName,PrimarySmtpAddress,@{n='EmailAliases';e={$_.EmailAddresses -cnotmatch 'SMTP:|SPO:|SIP:|[xX]500:' -replace 'smtp:','' -join ',' }}
DisplayName PrimarySmtpAddress EmailAliases
----------- ------------------ ------------
Barbie Smith bsmith@contoso.com barbie@contoso.onmicrosoft.com
Clement Jones cjones@contoso.com clement@contoso.onmicrosoft.com
If you'd like to export this to CSV, replace the -join parameter with a semicolon, and pipe to Export-Csv like so:
Get-Mailbox | select DisplayName,PrimarySmtpAddress,@{n='EmailAliases';e={$_.EmailAddresses -cnotmatch 'SMTP:|SPO:|SIP:|[xX]500:' -replace 'smtp:','' -join ';' }} | Export-Csv -Path 'C:\Path\To\Export.csv' -NoTypeInformation
Get group membership
Get a list of distribution and Microsoft 365 Teams and their members.
Get-Group | where { $_.RecipientType -ne "Group" } | select DisplayName,@{n='Members';e={ $_.Members -join ',' }
Follow the same process as above to export to CSV.
Grant-SPOPersonalSiteCollectionAdmin
Use this script to grant an admin or migration account the CollectionAdmin role to all personal SharePoint Online sites (OneDrive). This is required if using a single migration account to copy OneDrive data to a new tenant.
Before running this script, install and import the SharePoint Online PowerShell module:
Install-Module Microsoft.Online.SharePoint.PowerShell
Import-Module Microsoft.Online.SharePoint.PowerShell
The script will connect to the SPO Admin center with the configured admin center URL:
# Set the SharePoint Admin page URL
$AdminUrl = 'https://contoso-admin.sharepoint.com'
You will also need to set the UPN of the migration account:
# Set the migration account name
$MigrationAccount = 'migration@contoso.com'
