Summary

Create-MailboxBatches.ps1 is a PowerShell script that uses Exchange PowerShell to retrieve a list of mailboxes and then create batch files (with one mailbox address per line) for further processing (e.g. used as input parameters for some of the EWS scripts in this repository).

Example

.\Create-MailboxBatches.ps1 -Credentials (Get-Credential) -ExportBatchPath "c:\temp\batches" -BatchSize 50

The above will create text files containing lists of mailboxes in the path c:\temp\batches. Each text file will consist of the primary SMTP address of the mailbox, one per line. There will be 50 mailboxes per file.

Parameters

-Credential: Credentials used to authenticate with Exchange PowerShell (provided as PSCredential).

-PowerShellUrl: Exchange PowerShell Url (default is Office 365 Url: https://ps.outlook.com/powershell/).

-Filter: Use to apply a filter (same as Get-Mailbox -Filter parameter, as it is simply piped to that).

-OrganizationalUnit: Use to apply a filter (same as Get-Mailbox -OrganizationalUnit parameter, as it is simply piped to that).

-ExportBatchPath: Specifies the folder in which the batch files will be created.

-BatchSize: Maximum number of mailboxes per batch (default is 25).
