Microsoft 365 lets you share mailboxes, calendars, contacts and edit documents in real-time through collaborative tools. Sharing calendars in Exchange means you can see who in your organisation is available when, so you can schedule meetings that work for everyone, first time round. Shared mailboxes mean multiple people can access the same mailbox, so messages can be filtered to land in the shared mailbox and won't be missed. SharePoint is another integral tool for enabling collaboration. Documents saved here can be accessed and worked on by any staff member and shared as a link in the email. Multiple users can also edit documents stored in SharePoint in real-time, making co-authoring easy. You can see who is in the document at any time and even where they're working, thanks to little coloured flags which identify each user.
