Hi Jforsgren,
Thanks for your information.
According to the situation, I’d like to clarify the following scenarios:
1. If you have set up your local AD and want to sync the users in your local AD to Office 365, you can deploy DirSync.
2. If you have set up your local AD and you want to sync your Office 365 users to your local AD, sorry that this feature is unavailable at this time. Currently, we only support one-way Sync from local AD to Office 365.
Sorry for any inconvenience caused, and if there is anything unclear, please feel free to let me know, and I’m happy to provide more information.
Moreover, if you have some concerns about the second scenario, I suggest you submit feedback here about this valuable suggestion. Our product teams will hear your voice directly and help us improve Office 365 service. As far as I know, many features have been designed and upgraded based on customers' feedback. We always want to provide users with a better experience.
Thanks,
Vivian Wang
