We have been waiting for this feature for syncing custom Attributes to Office 365 and it is available in AD Connect Sync.  The only problem is that when I choose the custom attribute sync my custom attributes won't show up.  Microsoft tech support won't help because it is in preview.  Has anyone else tried this and had success?

Hello

Greetings!

We are pleased to answer your query. With regards to your query, As i understand from above post, you are not able to select "A specific attribute" Custom Attributes on Uniquely identifying your users page.

This option would allow you to select your own attribute, however the limitation being that you need to pick an attribute which will already exist in the meta verse. If you pick a custom attribute the wizard will not be able to complete.

You may refer configure custom attributes in AAD Connect.

Hope this helps!
Best Regards
Kamalakar
