Azure AD synce with On premise AD

Question

So here's the scenario i'm having. i installed the azure AD connect tool on my on prem DC. everything worked great except one item. I just did the default express install and of course that included my whole OU of the company. which in turned imported every user on that domain. I then followed these steps to correct my issue. customized it selected only OU's we want to sync to Azure AD from our on prem domain.

I have forced replication in the azure AD sync tool via powershell, waited for almost 4 hours and users are still in azure AD that arent in the selected OU's we had selected. how do i got about getting those users out of azure AD that aren't in the OU's we only want synced from on premi AD. Thanks as always for any help.

Answer 1

Have you forced a full or delta sync from on prem to aad after your custom configuration of aad connect?
After a full sync you could remove the aad object with the powershell cmdlets mentioned in your link, I think.

Answer 2

This is now resolved.
Csuttirp you def had one part which helped right full sync

so heres what i had to do from this article
https://www.reddit.com/r/Office365/comments/b9ousl/removed_a_ou_from_ad_sync_how_long_till_the_users/

steps
since i had over 500 objects had disable this threshold Disable-ADSyncExportDeletionThreshold

then ran full sync
Start-AdSyncSyncCycle -PolicyType Initial

and everything synced up correctly..
