After New installation of exchange 2016 , I wasn't able to access receive connector tab in ECP giving the below error :


500 unexpected error :(
an error occurred and your request couldn't be completed. please try again
==========

The following actions had been done with no success:
Server had been restarted
Services had been restarted

I tried also to use Exchange Management Shell with the following command:

Get-ReceiveConnector

And it list the receive connectors
but we get the below error:
===================
Property PermissionGroups can't be set on this object because it requires the object to have version 0.1 (8.0.535.0) or later. The object's current version is 0.0 (6.5.6500.0).
===================

You've got an old legacy connector in AD. Is there an old server listed?

Check through ADSIEDIT
CN=Configuration -> CN=Service -> CN=Microsoft Exchange -> CN=Domain Name -> CN=Administrative Group -> CN=Servers -> CN=Server name -> CN=Protocols -> CN=SMTP Receive Connectors

The production server is an old server (Exchange server 2010) and we want to migrate it to Exchange 2016, so I tried to check the path you mentioned and I found an old exchange server listed ..

Should I remove it?

If yes, is there a safe way to remove these records (e.g. Backup)?

Hi @MohamedMuaweya-3693

Agree with the suggestion above from Andy, the error informtion "Property PermissionGroups can't be set on this object because it requires the object to have version 0.1 (8.0.535.0) or later. The object's current version is 0.0 (6.5.6500.0)." indicates that there is an old Exchange object still left in AD.

What's you newly installed Exchange server version and how many Exchange servers are there in your environment currently?

Check the path in ADSIEdit provided above to remove the legacy connector then verify the result again. And if the operation still not work, try the below steps:

  1. Recycle MSExchangeECPAppPool in Application Pools from IIS Manager. Application Pools > MSExchangeECPAppPool > Recycle.

  2. Run UpdateCas.ps1 and UpdateConfigFiles.ps1 from the exchange bin directory C:\Program Files\Microsoft\Exchange Server\V15\Bin.

  3. Restart IIS by running iisreset /noforce from a command prompt window and check the result.

We could also have a go by recreating the ecp virtual directory and see the results.

  Remove-EcpVirtualDirectory -Identity <ecpvirtualdirectory>
  New-EcpVirtualDirectory -Server <servername> -ExternalURL <externalurl> -InternalURL <internalurl>

Restart IIS

The newly installed Exchange Server : Exchange Server 2016

The current production server : Exchange Server 2010

Is there a safe way to backup ADSIEdit prior removal of legacy connectors?

Hi @MohamedMuaweya-3693

Yes, we need to backup before making changes to ADSIEdit. Here I found an article introduces about HOW TO BACKUP AND RESTORE ACTIVE DIRECTORY: STEP-BY-STEP GUIDE for your reference.

Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.
In addition, if you have further question about the backup for AD, it's better to ask this question include AD related tags, thanks for your understanding!
