I subscribe to Office 365. Using Outlook 2013 on desktop PC and laptop. 3 email addresses using the same domain. All 3 work perfectly on the laptop but only one (my main one) works perfectly on the desktop. People and Calendar seem to sync perfectly on both machines. Email syncs perfectly on my main email account. But the other 2 email accounts don't work al all. Both seem to be setup exactly the same. Can anybody give me a clue what to look for please?
