Currently we have a client who is essentially using Office 365 purely for the Office licences rather than for email. They just put in an on-premise Exchange 2016 server over the summer but one of the users would like to be able to use Skype for Business online but have it synchronize with her local Exchange profile for contacts.
Their Office 365 is currently still setup with a *****@*****.onmicrosoft.com account as they don't route email or anything else through it. It doesn't really make sense to me to hybridize the deployment as it is literally only one user who would ever use the Skype service, and they have no intentions in the foreseeable future to have any sort of mail delivery performed to Office 365.
What I'm wondering is if there is another way to have continuous synchronization of her contacts between the Office 365 account and her local account? And if the only option is to hybridize the deployment, can this be done to only allow for Skype for Business not email?
