Hi,

I can't find any ExtensionAttribute in Attribute Editor, I know it needs extend AD schema, but when I finished "Setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms" use Exchange 2013, I still can't see ExtensionAttribute.

Hi Tim,

Based on my knowledge, the custom attributes (from ms-Exch-Extension-Attribute1 to ms-Exch-Extension-Attribute15) are created by Exchange Setup. So I recommend you finish your Exchange server installation at first. And then check if these custom attributes are created.

Here is an article for your reference.

Hope this can be helpful to you.

Hi Amy,

I need custom attributes, but I don't hope to install Exchange, do you have other experience for this?

Hi Tim,

If you need custom attributes, you need to install Exchange. I couldn't find other method to do it. Your understanding will be appreciated.
