Exchange Server 2019 ECP编辑异常求助：编辑内容变为代码无法保存或再次编辑

Hey there, sorry to hear you're stuck with this annoying issue on your brand-new Exchange 2019 server—having your ECP edits turn into garbled code and lock you out of saving or editing again must be a huge headache! Let’s go through some practical troubleshooting steps that often fix this kind of problem:

• Check ECP Virtual Directory Encoding Settings
  Sometimes incorrect content encoding can cause this garbled display. Fire up the Exchange Management Shell and run this command to check the current settings:
  Get-EcpVirtualDirectory | Select-Object Identity, ContentEncoding
  If the ContentEncoding isn’t set to UTF-8 or looks off, adjust it with this command (replace "YourServerName" with your actual server name):
  Set-EcpVirtualDirectory -Identity "YourServerName\ecp (Default Web Site)" -ContentEncoding UTF-8

• Clear Browser Cache & Try Private Browsing
  Outdated browser cache or corrupted cookies often clash with the ECP’s UI. First, try opening ECP in incognito/private mode—if the editing works normally here, clear your regular browser’s cache and cookies, then log back in to test.

• Update Exchange Server to the Latest Cumulative Update
  New installations might be missing critical CUs that patch ECP UI bugs. Use this command in EMS to check your current version:
  Get-ExchangeServer | Select-Object Name, AdminDisplayVersion
  Grab the latest compatible CU from Microsoft’s official resources, install it (don’t forget to back up first!), then restart the server and test ECP again.

• Recycle ECP App Pool & Restart IIS
  A glitchy IIS application pool for ECP could be the culprit. Open IIS Manager, navigate to Application Pools, find the ECP pool, right-click it and select Recycle. Then run this command in Command Prompt to restart IIS:
  iisreset
  Wait for the service to come back up, then log into ECP and try editing again.

• Disable Third-Party Extensions/Modules
  If you’ve installed any third-party Exchange management plugins or IIS modules, they might interfere with ECP’s rendering. Temporarily disable these components, restart the server, and see if the problem goes away.

If none of these steps work, it’d help to share more details—like which specific ECP section you’re editing (mailbox, distribution group, etc.) and a snippet of the garbled code you’re seeing. That’ll let us narrow down the issue further!
