Question

我们正在将用户邮箱从本地交换迁移到Office 365.由于我们一次只做少量用户，因此我们要求将本地Outlook客户端签名同步到Office 365 OWA门户。因此，用户在其OWA门户上看到相同的签名。

有没有人这样做过？

Answer 1

我已经弄清楚了。所以我创建了一个脚本来帮助我们的迁移团队将本地Outlook客户端签名上传到Office 365。

您需要拥有对用户PC的管理员权限并交换在线管理员权限，例如全局管理员。

以下是代码：

write-host "`n`n`n`n"

#initializing variables
$username = $null
$computer = $null
$path = $null
$number = $null
$i = 0
$select = $null
$signs = $null
$chkerr = $false
$session = $null

#Run a continous loop
do {

    #if powershell is not connected to office 365 then run the connection code below
    if ($session.State -ne "opened") {

        Write-Host "`nChecking connection to Office 365: " -NoNewline
        Write-Host "Inactive!" -ForegroundColor white -BackgroundColor red

        Write-Host "`nConnecting to Office 365 account...`n"

        #Get user office 365 credentials 
        $UserCredential = Get-Credential

        #create session
        $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

        #start the session to office 365
        Import-PSSession $Session
        Sleep 4
    }

    #if the session to 365 is success then run the code below
    if ($?) {
        Write-Host "`nChecking connection to Office 365: " -NoNewline
        Write-Host "Active!" -ForegroundColor Black -BackgroundColor green

        #Start a loop to prompt for username and machinename
        do {

            #this variable is used below and set as false if there is an error. Also, shows a message that user need to re-enter the information 
            $chkerr = $false
            if ($chkerr) {write-host "`nPlease try again..." -BackgroundColor yellow -ForegroundColor black}

            #store username and machine name
            $username = Read-Host "`n`nPlease enter user name"
            $computer = Read-Host "Please enter computer name"

            #if machine is not pingable then show an error
