Just can't get enough of IT

This blog is about mostly anything in IT. But the primary focuses are Microsoft Technologies like Exchange, Office 365, Azure and Cloud Security.

Office 365 Hybrid Mailbox Migration Management

Michael Hall of MCS has published on excellent Excel tool to simplify the migration of on-premise Exchange mailboxes to Office 365.

The script does support not special characters in display names as it is intended to work with ASCII files.

The textfile type used by Excel VBA code has been changed from 437 to 65001.

When you want to use the attached Excel file you are required to create an UTF-8 export when collecting mailbox data. The required PowerShell code is as follows:

$mbx=Get-Mailbox -resultsize unlimited; $mbx | foreach-object {$UPN = $_.UserPrincipalName; $EmailAddress = $_.PrimarySmtpAddress;$OU = $_.OrganizationalUnit; $Type = $_.RecipientTypeDetails; $_ | Get-MailboxStatistics | select @{Name="UPN";expression={$UPN}},@{Name="EmailAddress";expression={$EmailAddress}},@{Name="Type";expression={$Type}},@{Name="OU";expression={$OU}},DisplayName,@{Name="TotalItemSize(MB)";expression={$_.TotalItemSize.Value.ToMB()}},LastLogonTime}|Export-csv .\Mailboxes_Output.csv -notype	-Encoding UTF8

Then just follow the instructions provided in Michaels blog post.
