Online Calendars not working for Non Internet Users
we use Microsoft Exchange 2019 on premise and have been migrating resource calendars to the O365 Microsoft Exchange. We have a few sections of network that we keep off the internet on purpose. Those users are having issues connecting to Resource Calendars because they are prevented from the internet. Is there a way to resolve this? Makes sense why there is an issue but is there a proxy or something that could be setup to allow the Non-Internet users from having no issues connecting to the O365 Exchange Resource calendars? Thank You Eddie
