如何将会议导入 office365（EWS 和 Powershell？）

Question

我需要协助将预订/会议导入 office365。我可以将我们旧的基于 Web 的系统中的预订信息导出到 csv 中，但需要一种方法来导入到 office365 中的交换中。

我发现的最有前途的方法是使用 Exchange Web 服务通过 powershell 连接到云，然后使用模拟将预订重新定义为针对新创建的房间邮箱的适当用户。但如果有更好的方法，我愿意接受其他建议。

我目前在使用 EWS 和 powershell（例如：http://mikepfeiffer.net/2011/01/creating-calendar-items-with-powershell-and-the-ews-managed-api/）时遇到的问题是，当我尝试连接时出现自动发现错误。使用 office 365 仍然可以做到这一点吗？

更新： 嗨格伦秤，

非常感谢您的示例，看起来很有希望，但是当我在上面运行您的代码时，我仍然遇到自动发现错误，具体错误以及我在下面逐步说明的操作。我希望我做的事情显然是错误的，你将能够纠正我

我正在运行 powershell 并使用我们的凭据连接到 o365，如下所示：

$loginUserName = "admin@domain.onmicrosoft.com"
$PWord = ConvertTo-SecureString –String "secret" –AsPlainText -Force
$Credential = New-Object –TypeName System.Management.Automation.PSCredential –ArgumentList $loginUserName, $PWord
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $Credential -Authentication Basic -AllowRedirection
Import-PSSession $Session
Connect-MsolService -Credential $Credential

然后加载你的函数并尝试这样的测试命令：

$Start = Get-Date
$End = (Get-Date).AddHours(1)

Create-Appointment -MailboxName mymailbox@domain.com -Subject "Test appointment" -Start $Start -End $End -Body "Test Body" -Credentials $Credential -Location "sdfkjhsdfjh"

错误：

您需要确保在 Office365 中使用凭据，否则您将收到自动发现错误，例如应该可以正常工作
