使用 PowerShell 连接到 Exchange 365 为自定义域设置 DKIM

我对 Office 365 为一堆自定义域设置 DKIM 感到非常沮丧。我需要使用 PowerShell 登录到 Exchange 系统，并使用只有 Microsoft 可以发明的语法来做一些巫术。

这些是我的资源：

https://docs.microsoft.com/en-us/powershell/exchange/exchange-online-powershell-v2?view=exchange-ps#install-and-maintain-the-exo-v2-module

https://docs.microsoft.com/en-us/powershell/exchange/connect-to-exchange-online-powershell?view=exchange-ps

安装依赖

Install-Module -Name ExchangeOnlineManagement -RequiredVersion 2.0.3
Set-ExecutionPolicy RemoteSigned
Import-Module ExchangeOnlineManagement

我对所有问题的回答都是肯定的，这似乎有效。

Connect-ExchangeOnline -Credential $UserCredential -ShowProgress $true -ExchangeEnvironmentName O365GermanyCloud

【解决方案1】：

命令在没有ExchangeEnvironmentName 的情况下工作：

Connect-ExchangeOnline -Credential $UserCredential -ShowProgress $true

所需的用户是user@customdomain.com。

【解决方案2】：

就我而言，我的帐户已启用 MFA。所以有效的命令是：

Connect-ExchangeOnline -UserPrincipalName navin@contoso.com -ShowProgress $true

替换您的用户名，并期望使用 Microsoft 身份验证器进行身份验证。
