Yes, I do think so!  :-)

At least for up to about 100 users (that's the size of the businesses
we usually have as our customers)

We implemented Linux-based groupware solutions for those clients in the past
(and hopefully will do in the future) based on the following main components:

*) Linux (CentOS, SLES, OpenSUSE, depending on customers preferences)

*) Cyrus IMAP

*) Sendmail [sic]

*) OpenLDAP

*) SOGO (nobody mentioned SOGO yet, but IMHO it works very well and integrates perfectly into the Linux software stack!)

*) Fusiondirectory (was GOSa)

*) And the usuall suspects like ClamAV, SpamAssassin, ...

This solution provides:

*) Basic Mail (Relay, Server, Storage, ...)

*) Webmail (through SOGO)

*) Calendar and address book Web UI

*) Calendar and address book for a desktop client like Thunderbird (CalDAV, CardDAV)

*) Web-Based Admin UI for both admins and users (to manage their own accounts)

*) Integration with smartphones (mail, calendar, address book)

*) Features like shared mailboxes, shared calendars, ...

*) Easy integration with all typical Unix/Linux services (Fileserver, Webserver, VPN, ...)

I have no experience with Exchange (and I refuse to get any),
but I have "some" with Unix/Linux (since 1990. Yes I'm old ;-)

For me the above mentined software stack "just works" and it
does for the more advanced business use case, too.

I can't say anything about solutions for thousands of users, though, so YMMV!
