Someone in our company has created a Yammer network at company domain e.g. @abcxyz.com. Company started using Office365 this year and @abcxyz is a registered domain in O365.
We want to bring the exiting Yammer network under O365. However when we go to Yammer admin centre, domain @abcxyz doesn't come up. Currently it's selecting @abcxyz.onmicrosoft.com domain as the primary domain.
Any one out there handled a similar scenario or can offer any guidance.
