Hi all,

I've spent a lot hours trying to do this, but I've unable to, I hope someone can lend me a hand.

SCENARIO: I have four computers with Windows 10 and Office 2016. The same gmail account is configured in all them using POP3, so this account is shared between four users, all them receives the same mails, etc.

Those users mark the received mails categoryzing them with colors (red, yellow, blue...). In this way they can identify the state every mail is in (answered by himself, answered by other user, don't need answer...).

PROBLEM: Since those marks are made locally in the pst file, when a user mark a mail in a color, the other users doesn't see this mark, so the have to ask mail by mail to the colleages about every mail (up to hundred per day).

NEED: I need those colors/flags/categories of inbox mailbox to be shared/syncronyzed among the four computers (the content of inbox folder is the same in all computers since it's the same mail account).


I've try a few third party programs that promised to do it, but none of them works, the others options seems to be:

1.- Using IMAP instead of POP3, problem: given the huge quantity of mails, when I tryed this some time ago it didn't work well, everything went very slow outlook even gets frozen sometimes. Besides that, IMAP doesn't support color categories.

2.- Using Exchange Server? This could be a solution (I'm not sure), but I'm afraid it requires a domain and a Windows server O.S, but we have a workgroup and Windows 10 Professional. Of course, if it would be my only solution I'd have to do this.

I hope someone can lend me a hand, may thanks in advace.
