Get-Mailbox UserName | fl ExchangeGuid #取得 ExchangeGuid
PowerShell On-Premises
Enable-RemoteMailbox UserName -RemoteRoutingAddress UserName@YourDomain.mail.onmicrosoft.com
Set-RemoteMailbox UserName -ExchangeGuid <ExchangeGuid from above>
如果是 Shared Mailbox, Enable-RemoteMailbox 指令加上 -Shared 參數

運動攝影機錄影擋預設流量 (bitrate) 很高,但其實我覺得看不太出來高低流量畫質的差異
所以根據網路查的一些建議用 ffmpeg 批次處理降低流量
先用 ffprobe.exe 取得影片屬性,再根據影片屬性進行處理
以下 Powershell 中,VideoRotation 是影片方向的資訊,在降低流量的處理中實際上不需要
這裡只是當作筆記用,未來有需要的時候才找得到 (找很久才找到這個語法)
#設定要降低的 bitrate 值 Start
$ProcessMethod = @();
$ProcessMethod += New-Object -TypeName PSObject -Property @{
Width = 2688;
FrameRate = 30;
BitRate = 16;
};
$ProcessMethod += New-Object -TypeName PSObject -Property @{
Width = 2688;
FrameRate = 60;
BitRate = 24;
};
$ProcessMethod += New-Object -TypeName PSObject -Property @{
Width = 3840;
FrameRate = 30;
BitRate = 45;
};
$ProcessMethod += New-Object -TypeName PSObject -Property @{
Width = 3840;
FrameRate = 60;
BitRate = 55;
};
$ProcessMethod += New-Object -TypeName PSObject -Property @{
Width = 3840;
FrameRate = 120;
BitRate = 65;
};
#設定要降低的 bitrate 值End
全景影片用 VLC 等媒體播放軟體播放時若預設不以全景模式播放代表缺少 Metadata Tag
解決辦法如下,如果檔案量少,可以直接用 GUI 程式處理,檔案多的話跑批次比較省事
GUI & Source: google spatial-media
https://github.com/google/spatial-media/releases
Command 需要 python 2.7 (新版不行)
根據影片類型可能要加入 StereoMode 參數,請自行參考程式說明
先轉轉看確認參數再跑批次
Set-Location -Path "D:\Software\spatial-media-2.1\";
$Files = (Get-ChildItem -Path 'D:\Video' -File)
foreach ($File in $Files) {
& D:\Python27\python.exe spatialmedia -i $File.FullName ($File.FullName -Replace $File.BaseName,($File.BaseName + '_360 Tag Added'));
#if (($File.FullName -Replace $File.BaseName,($File.BaseName + '_360 Tag Added')) -eq $True) {
# remove-item -path $File.FullName -force;
#};
};

在 PowerShell 中用帳號密碼進行 Connect-AzAccount 會被罵
WARNING: Authentication with a username and password at the command line is strongly discouraged. Use one of the recommended authentication methods based on your requirements. For additional information, visit https://go.microsoft.com/fwlink/?linkid=2276971.
先用具有適當權限的帳號登入後用以下 Script 建立 Service Principal Application
再到 RBAC 賦予需要的權限
Set-Location -LiteralPath 'C:\Command\AzureConnect';
$AzureEntraTenantId = 'xxxxxxxx-xxxx-xxxx-xx-xxxxxxxxxxxx';
$AzSubscriptionID = 'xxxxxxxx-xxxx-xxxx-xx-xxxxxxxxxxxx';
$ServicePrincipalName = 'PowershellAutomaticProcess';
$CredentailFileName = ('AzConnect_' + $ServicePrincipalName + '.txt')
$CertificateExpired = 100;
#設定密碼 100 年後到期 (預設 1 年),往下找 AddYears 字串那邊可以改
這支 Powershell Script 蒐集以下資訊並以 JSON 格式存到 Share Folder
LogonServer
Site
UserName
ComputerName
ComputerInfo
DiskInfo
Applications
NetworkInfo
GroupsInfo
LocalUsers
用 GPO 派送,目標 Share Folder 給予 User 建立 Child Object 權限
並給予 Creator Owner 刪除權限
以 User Name + Computer Name 為檔名,後加上日期年月日時分秒
保留最新的 5 個 Report
繼前一篇 Synology Active Backup for Business for Hyper-V VM Failed to Backup #01
取得 Patch 跳過了 5 個 Snapshots 的問題後
還是備份失敗
於是再用 Support Center App 產生 Active Backup for Business 的 Debug Log 後
在 ActiveBackup\volume1\@ActiveBackup\log\vm.log 中看到
synoabk_vm_backup[6175]: synoabk_vm::[WARNING] hyperv_agent.cpp:1381(6175,139923524343360) [6175]hypervisor_agent/hyperv_agent.cpp:145 {"error_class":"PowerShellException","error_message":"Missing an argument for parameter 'Id'.

難道是 Powershell 語法錯誤少帶一個參數?
