We have a hybrid solution setup between our On-Prem MS Exchange (2010) and O365. We have one problem where O365 users cannot see the free/busy information of any new domain added to the On-Prem Exchange (See attached). All the other domains we have and that were setup when the hybrid solution was deployed, still work fine (we can see free/busy). This only happens with new domains we setup for email.
Please can someone point me in the right direction to have this issue resolved?
