Hi, Can anybody give use some suggestions please. We have ordered 5 subscriptions of office 365 recently. Our goal is: two emails are: '[email protected]' and '[email protected]', which need to be checked by 3 different staff. So everybody can put a 'categories' mark on each received email and others can see it has been replied or need actions. The other three emails are for three individuals. These emails don't need to be share each other, but we want to share the calendars between them. After reading some posts here, we know office 365 can do above jobs. However after purchasing them, we noticed rather than using our own email address(@xxx.com), office provide different email account which is similar as @xxx.onmicrosoft.com. Now, the problem is how can we replace Microsoft email to be our own one. I noticed there is a post said we can change the DNS, but not much details on that post. We don't want to redirect the email server to office 365 since we still have other three very rarely used emails(e.g. [email protected]). Don't think its worthy to pay £9.8/month to receive 20 emails per month. Thanks in advance.
