Set-MailUser 批量操作 - 更新 LegacyExchangeDN 时出现问题

Question

我正在使用 Microsoft 方式执行跨租户 O365 迁移。 资源： https://learn.microsoft.com/en-us/microsoft-365/enterprise/cross-tenant-mailbox-migration?view=o365-worldwide https://blog.matrixpost.net/office-cross-tenant-mailbox-migration/

我遇到的问题是在身份映射阶段，您通过设置主要 SMTP、ExchangeGUID 和 LegacyExchangeDN 来准备目标租户中的邮件用户。当我批量执行此操作时，LegacyExchangeDN 无法更改。

我已经通过 Exchange Online 证明我可以使用以下命令修改这些值：

set-mailuser -identity "CT Migration" -ExchangeGuid 55555555-5555-5555-5555-555555555555
Set-MailUser -Identity “CT Migration” -EmailAddresses @{add=”X500:/o=ExchangeLabs/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=55555555555555555555555555555555555555555-0″}

我面临的问题与 LegacyExchangeDN 值未得到修改特别相关（即使其他值已修改）。

下面是我制作的脚本 - 请记住，我正在导入带有我想要设置的值的 csv。另外，我在设置 cmd 之前和之后导出获取结果：

# Step 1: Bulk Get-MailUser and export to CSV
$csvFile = "C:\Scripts\SetMailUserBulk.csv"
$outputFile = "C:\Scripts\PriorToSet.csv"

$users = Import-Csv $csvFile
$attributes = "Name", "LegacyExchangeDN", "ExchangeGUID", "UserPrincipalName", "PrimarySMTPAddress", "ExternalEmailAddress"

$users | ForEach-Object {
    $user = $_
    $mailUser = Get-MailUser -Identity $user.Identity | Select-Object $attributes
    $mailUser | Select-Object $attributes | Export-Csv -Append -Path $outputFile -NoTypeInformation
}

# Step 2: Bulk Set-MailUser
$updatedUsers = Import-Csv $csvFile

$updatedUsers | ForEach-Object {
    $user = $_
    $mailUser = Get-MailUser -Identity $user.Identity

    Set-MailUser -Identity $user.Identity `
        -ExchangeGuid $user.ExchangeGuid `
        -EmailAddresses @{Add = "X500:$($user.LegacyExchangeDN)"}
}

# Step 3: Bulk Get-MailUser after modification and export to CSV
$modifiedOutputFile = "C:\Scripts\AfterSet.csv"

$updatedUsers | ForEach-Object {
    $user = $_
    $mailUser = Get-MailUser -Identity $user.Identity
    $mailUser | Select-Object $attributes | Export-Csv -Append -Path $modifiedOutputFile -NoTypeInformation
}

我导入的 csv 中的 csv LegacyExchangeDN 值具有以下格式：

"/o=ExchangeLabs/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=555555555555555555555555555555555555555555555-1c"

我修改了导入的 csv 中的 LegacyExchangeDN 值，并添加了 @{Add = "X500: set cmd 的部分。我在输出中没有收到任何错误 - 脚本运行良好 - 唯一的问题是 LegacyExchnageDN 值是未从 set-mailuser cmd 进行修改。

所以事实证明我的输出不包含 -EmailAddresses 属性，并且没有反映 set cmd 所做的更改。

我还在脚本中连接了 x500 代理并创建了两个单独的 set-mailuser cmd。 以下是最终脚本：

# Step 1: Bulk Get-MailUser and export to CSV
$csvFile = "C:\Scripts\SetMailUserBulk.csv"
$outputFile = "C:\Scripts\PriorToSet.csv"

$users = Import-Csv $csvFile
$attributes = "Name", "EmailAddresses", "LegacyExchangeDN", "ExchangeGUID", "UserPrincipalName", "PrimarySMTPAddress", "ExternalEmailAddress"

$users | ForEach-Object {
    $user = $_
    $mailUser = Get-MailUser -Identity $user.Identity | Select-Object $attributes
    $mailUser | Select-Object $attributes | Export-Csv -Append -Path $outputFile -NoTypeInformation
}

# Step 2: Bulk Set-MailUser
$updatedUsers = Import-Csv $csvFile

$updatedUsers | ForEach-Object {
    $user = $_
    $mailUser = Get-MailUser -Identity $user.Identity
    $Email = "X500:" + "$($user.LegacyExchangeDN)"
    write-host "$Email"

    Set-MailUser -Identity $user.Identity -ExchangeGuid $user.ExchangeGuid -PrimarySmtpAddress $user.PrimarySMTPAddress
    
    Set-MailUser -Identity $user.Identity ` -EmailAddresses @{Add = "$Email"}
}

# Step 3: Bulk Get-MailUser after modification and export to CSV
$modifiedOutputFile = "C:\Scripts\AfterSet.csv"

$updatedUsers | ForEach-Object {
    $user = $_
    $mailUser = Get-MailUser -Identity $user.Identity
    $mailUser | Select-Object $attributes | Export-Csv -Append -Path $modifiedOutputFile -NoTypeInformation
}

Answer 2

Mailuser 不适合我。对于所有在线交换的用户来说，这并不一致。

仅适用于作为实际邮件用户创建的帐户。
