Hi 各位前輩
最近主管發現OneDrive所有使用者的預設時區都是UTC-8

所以小弟上網找了Script要批量修改所有User的時區為UTC+8

#Set Parameters
$AdminSiteURL="https://domain-admin.sharepoint.com"
$TimezoneName = "(UTC+08:00) Taipei"
 
#Get Credentials to connect
$Cred  = Get-Credential
  
#Connect to PnP Online to the Tenant Admin Site
Connect-PnPOnline -Url $AdminSiteURL -Credentials $Cred
  
#Get All OneDrive for Business Sites
$OneDriveSites = Get-PnPTenantSite -IncludeOneDriveSites -Filter "Url -like '-my.sharepoint.com/personal/'"
 
#Loop through each site
ForEach($Site in $OneDriveSites)
{
    Write-Host -f Yellow "Processing Site: "$Site.URL
 
    #Connect to OneDrive for Business Site
    Connect-PnPOnline $Site.URL -Credentials $Cred
  
    #Get the Web
    $web = Get-PnPWeb -Includes RegionalSettings.TimeZones
  
    #Get the time zone
    $Timezone  = $Web.RegionalSettings.TimeZones | Where {$_.Description -eq $TimezoneName}
  
    If($Timezone -ne $Null)
    {
        #Update time zone of the site
        $Web.RegionalSettings.TimeZone = $Timezone
        $Web.Update()
        Invoke-PnPQuery
        Write-host "`tTimezone Updated Successfully!" -ForegroundColor Green
    }
    else
    {
        Write-host "Timezone $TimezoneName not found!" -ForegroundColor Yellow
    }
     
    Disconnect-PnPOnline
}

用戶約為200人
腳本的驗證是用全域管理員權限 我也勾了SharePoint管理員

但結果只有一半的使用者成功修改了時區
另一半使用者都會跳出以下結果

已經確定登入的帳號有管理權限了
但是還是無法理解為什麼部分人修改時區還是失敗
