Here are the most reliable ways to determine your Exchange Server version and build information.

MS-Exchange-Server

 

 

1. PowerShell Commands (Most Common Method)

Basic Command

Get-ExchangeServer | Format-List Name,Edition,AdminDisplayVersion

Sample Output:

Name                 : EX01-2019
Edition              : Standard
AdminDisplayVersion  : Version 15.2 (Build 1544.4)

Multiple Servers in Table Format

Get-ExchangeServer | Format-Table Name,Edition,AdminDisplayVersion

Check Specific Server

Get-ExchangeServer -Identity "ServerName" | Format-List Name,Edition,AdminDisplayVersion

 

 

2. Health Checker Script (Most Detailed Information)

Download and Run

  1. Download HealthChecker.ps1 from Microsoft’s official GitHub repository
  2. Run with elevated PowerShell:
.\HealthChecker.ps1 -Server "ServerName"

Generate HTML Report for All Servers

Get-ExchangeServer | .\HealthChecker.ps1
.\HealthChecker.ps1 -BuildHtmlServersReport

Key Advantage: Shows exact CU and SU installation status

 

 

3. Exchange Admin Center (EAC)

Access Steps

  1. Open browser and navigate to https://servername/ecp
  2. Sign in with administrator credentials
  3. Click Servers → Servers tab
  4. View version information in the server list

 

 

4. File Version Check

ExSetup.exe File Information

Get-Command Exsetup.exe | ForEach {$_.FileVersionInfo}

Sample Output:

ProductVersion   FileVersion      FileName
--------------   -----------      --------
15.02.1544.004   15.02.1544.004   C:\Program Files\Microsoft\Exchange Server\V15\bin\ExSetup.exe

 

 

5. Registry Check

Registry Path

  1. Run regedit
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v15\Setup
  3. Check these values:
    • MsiProductMajor
    • MsiProductMinor
    • MsiBuildMajor
    • MsiBuildMinor

Important Notes

  • Health Checker: Most accurate information (shows both CU and SU status)
  • Required Permissions: Organization Management or View-Only Organization Management
  • Hybrid Environments: Latest CU installation required
