Hi Guys,
I'm performing Mail Migration to Office 365 from Exchange 2010(On SBS 2011). While performing the preparations, I installed DirSync and Configured it(without the "hybrid deployment " checkbox); Then I decided to perform "Cutover migration" ,when I found out that Hybrid deployments require an on-premises Exchange server.
Problem / Question: I need to remove On-premises exchange after the migration but I cannot perform a cutover migration with dirsync configured. I tried to deactivate Dirsync and create a batch with an endpoint but, of course, it fails telling me that and object already exists in target forest.

Is there a way to remove, Dirsync, then remove all users, groups, etc from Office 365, then run a cutover migration, then install Dirsync? Or Is there anything else I can do to revert what I have done?

What I would like to do is:
-move all mailboxes to office 365
-configure Dirsync for Password syncronization

exactly like you said:
remove (or easier) disable dirsync
connect with powershell to office365 (connect-msol)
Run this code in powershell:
Set-MsolDirSyncEnabled –EnableDirSync $false

Open in new window

Check if dirsync is disabled with this code: (this can take up to 72 hours according to documentation, but you come from an SBS, so not much users, so not much time needed)
(Get-MSOLCompanyInformation).DirectorySynchronizationEnabled

Open in new window

remove the users in office365 website

That did it. The mailboxes are pop-ing up on the O365 EAC like mushrooms after rain
Thank you Very Much!
