Spiceheads,
I'm back, at a new job, in a new environment with new challenges!
I've inherited an Office 365 environment that lives in the cloud. Meaning that it's not sync'd or related back to the DC on premise. This is causing issues where I can't manage the Cloud AD through the on-prem AD. Meaning any change has to be manually copied over to the other environment.
Now, the issue - or questions rather that I have is; can I simply start DirSync on the DC and the accounts will magically match up? Or will that drop the 400GB+ of email that's stored in the Exchange Online arm of Office 365?
Any further information needed - just ask,
