I am using Outlook 2016 and Exchange 2013. My main outlook account works and syncs properly, but another user has his mailbox and everything share with me. I have everything shared with editor permissions. I can make additions to this person's calendar, but they do not sync with their end until I go up and manual click "update folder". Also the inbox and sent folder do not sync unless I click them specifically and then go to "Update Folder". Anytime I click "update folder" the folder that I am highlighting syncs. Why isn't everything just syncing automatically like everything does on my regular account.
