如何在提供的PowerShell脚本示例中使用Office 365 REST API删除邮件项目

标签： api rest email powershell office365

我一直试图找到这个问题的解决方案已经有一段时间了，我发现的任何东西似乎都没有用。我希望使用这个脚本：

##-----------------------------------------------------## 
##        PICK AUTH Method                             ## 
##-----------------------------------------------------## 

## HARD CODING PSW    ## 
#$password = ConvertTo-SecureString "xxx" -AsPlainText -Force 
#$cred = New-Object System.Management.Automation.PSCredential "xxx@xxx.onmicrosofot.com",$password 

## USER PROMPT PSW    ## 
#$cred = Get-Credential 

##-----------------------------------------------------## 
##    END PICK 
##-----------------------------------------------------## 

$url = "https://outlook.office365.com/api/v1.0/me/messages" 
$date = "2014-11-21" 

## Get all messages that have attachments where received date is greater than $date  
$messageQuery = "" + $url + "?`$select=Id&`$filter=HasAttachments eq true and DateTimeReceived ge " + $date 
$messages = Invoke-RestMethod $messageQuery -Credential $cred 

## Loop through each results 
foreach ($message in $messages.value) 
{ 
    # get attachments and save to file system 
    $query = $url + "/" + $message.Id + "/attachments" 
    $attachments = Invoke-RestMethod $query -Credential $cred 

    # in case of multiple attachments in email 
    foreach ($attachment in $attachments.value) 
    { 
        $attachment.Name 
        $path = "c:\Temp\" + $attachment.Name 

        $Content = [System.Convert]::FromBase64String($attachment.ContentBytes) 
        Set-Content -Path $path -Value $Content -Encoding Byte 
    } 
}

我从链接中找到了 - TechNet Office 365 Scripts

我可以让脚本正常工作，它连接到邮箱并下载日期变量后指定的电子邮件的附件。问题是我希望按小时计划运行此操作并删除以前处理过的电子邮件，以便在连续运行时不会删除它们的附件。

我尝试了很多不同的命令来删除电子邮件但没有成功，并尝试更改$ messageQuery以仅包含特定日期范围内的项目但无法正常工作。

任何人都可以在powershell中为delete命令提供正确的语法，并在此上下文中提供如何使用它的示例吗？

由于

富

更新 - 我认为加入：

$query2 = $url + "/" + $message.Id

和

Invoke-RestMethod $query2 -Credential $cred -Method Delete

让我靠近但现在我的手术时间已经过了。

更新 - 根据需要提供完整的代码：

##-----------------------------------------------------## 
##        PICK AUTH Method                             ## 
##-----------------------------------------------------## 

## HARD CODING PSW    ## 
$password = ConvertTo-SecureString "password" -AsPlainText -Force 
$cred = New-Object System.Management.Automation.PSCredential "email@address.co.uk",$password 

## USER PROMPT PSW    ## 
##$cred = Get-Credential 

##-----------------------------------------------------## 
##    END PICK 
##-----------------------------------------------------## 

#$url = "https://outlook.office365.com/api/v1.0/me/messages" 
$url = "https://outlook.office365.com/EWS/ODATA/me/messages"
$today = Get-Date -format yyyy-MM-dd 
$date = (Get-Date).AddDays(-2).ToString("yyyy-MM-dd")


## Set date and query  
$messageQuery = "" + $url + "?`$select=Id&`$filter=HasAttachments eq true and DateTimeReceived lt " + $today #+ " and DateTimeReceived gt" + $date
$messages = Invoke-RestMethod $messageQuery -Credential $cred 

## Loop through each results 
foreach ($message in $messages.value) 
{ 
    # get attachments and save to file system 
    $query = $url + "/" + $message.Id + "/attachments" 
    $query2 = $url + "/" + $message.Id
    $attachments = Invoke-RestMethod $query -Credential $cred 

    # in case of multiple attachments in email 
    foreach ($attachment in $attachments.value) 
    { 
        $attachment.Name 
        $path = "\\SomePath\" + $attachment.Name 

        $Content = [System.Convert]::FromBase64String($attachment.ContentBytes) 
        Set-Content -Path $path -Value $Content -Encoding Byte 

    } 

    Invoke-RestMethod $query2 -Credential $cred -Method Delete -TimeoutSec 100   

} 

#Move pdf files to another folder
#Move-Item '\\SomePath\*.pdf' '\\SomePath'

#Then delete any existing files from directory
#Remove-Item '\\SomePath\*'

我尝试更改日期部分以允许开始日期和结束日期，因此脚本可以每天运行一次，执行提取但不会重新处理前几天的附件，但遇到了解决语法的问题以更改$ messageQuery。

运行脚本的响应是：

Invoke-RestMethod：操作已超时。 在C：\ Scripts \ EmailExtractServiceContract365.ps1：26 char：13 + $ messages = Invoke-RestMethod $ messageQuery -Credential $ cred + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~     + CategoryInfo：InvalidOperation：（System.Net.HttpWebRequest：HttpWebRequest）[Invoke-RestMethod]，WebException     + FullyQualifiedErrorId：WebCmdletWebResponseException，Microsoft.PowerShell.Commands.InvokeRestMethodCommand

不是答案

使用Fiddler捕获请求。使用https://outlook.office365.com/api/v1.0/me/messages端点。另一个已被弃用（我认为）。在此处发布已清理的请求/响应。

您的脚本可能不是问题

我让脚本工作正常;它找到一封带附件的电子邮件，保存附件，然后删除电子邮件。在我看到请求之前，我不确定您的环境中发生了什么（如果您发布请求，请删除auth标头）。我今天只更改了$ today值以捕获带附件的电子邮件。

$password = ConvertTo-SecureString "password" -AsPlainText -Force 
$cred = New-Object System.Management.Automation.PSCredential "user@contoso.com",$password 

$url = "https://outlook.office365.com/api/v1.0/me/messages" 
$today = (Get-Date).AddDays(1).ToString("yyyy-MM-dd")
$date = (Get-Date).AddDays(-2).ToString("yyyy-MM-dd")

## Set date and query  
$messageQuery = "" + $url + "?`$select=Id&`$filter=HasAttachments eq true and DateTimeReceived lt " + $today #+ " and DateTimeReceived gt" + $date
$messages = Invoke-RestMethod $messageQuery -Credential $cred 

## Loop through each results 
foreach ($message in $messages.value) 
{ 
    # get attachments and save to file system 
    $query = $url + "/" + $message.Id + "/attachments" 
    $query2 = $url + "/" + $message.Id
    $attachments = Invoke-RestMethod $query -Credential $cred 

    # in case of multiple attachments in email 
    foreach ($attachment in $attachments.value) 
    { 
        $attachment.Name 
        $path = "C:\temp\" + $attachment.Name 

        $Content = [System.Convert]::FromBase64String($attachment.ContentBytes) 
        Set-Content -Path $path -Value $Content -Encoding Byte 

    } 

    Invoke-RestMethod $query2 -Credential $cred -Method Delete -TimeoutSec 100   
}

请求
