Outlook syncing/sharing.

Hi All,

Do we have any Outlook gurus here? Something I've never had to do before, and dont know how to start - even google searches arent helpful as I dont quite know what to ask. Enough waffling - to the scenario....

I have in my office 3 computers that all use outlook 365. The PCs are not in a domain (and unlikely to be part of one). All pick up the same emails - if one PC gets an email then all 3 pcs get the email. If one person answers an email it gets marked as read/actioned on that PC only. If the email gets moved to a different folder, then only that PC sees that it has moved.

What I want is a solution (ideally free) whereby if an email is moved out of the inbox, then it is moved on all PCs. The file structure on each PC is different - worker A moves dealt with emails into a "Dealt with" folder, whereas worker B moves emails into folders "A" or "C" depending on which worker has answered the original email.

Can such a system be set up? We have the option of setting up a 4th PC to act as a mail server, but do I need the PCs to be on a domain for that? Alternatively, one of the 3 original PCs can be used as the server if required. Using "the cloud" is not an option.

Any help would be greatly appreciated - even if its pointing me to a website - or even just telling me what I want - syncing/sharing/other Outlook.

Thanks in advance.
