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.
Thank you,
Mark
Also are there attachments on these emails that may be pretty large, or it there any malware and spam scanning on those emails?
