We have Exchange 365 setup in a hybrid mode. We are in the process of moving email accounts to the cloud. We have a distribution list for a group of people for daily emails that come out at 8:01 every morning. The number of emails varies from 20 up to 100. The distribution group has 6 people in it. We are seeing a 30 minute delay on some people getting the emails. I believe this has to do with a limit on the smtp email coming in. Is there a way to increase this limit? The group is on the premises Exchange at this time, so the addresses are getting resolved before going to the cloud.
