I'd like to hear how Microsoft Exchange's webmail (OWA) compares to Kerio webmail.

I've been asked to switch from a Kerio server to a hosted Exchange service. As an argument for the move, I was told that OWA is better than Kerio webmail. I did not have any experience with OWA so I simply took the statement at face value.

I've now spent some time comparing Kerio webmail with OWA and find that OWA comes up short. In fact, if you don't use OWA with IE, OWA Light (as MS calls it) is very weak.

My bias: I am not a fan of Microsoft. They do not design their software for me. I am a fan of companies like Kerio. They tend to be nimble and focus on the user. I like the Kerio server and find it easy to maintain and full-featured.

OWA's strengths compared to Kerio:

- Slightly more attractive UI. Obviously subjective.
- Feels faster. Again, subjective.
- Can search body
- Can define which folders to search
- Can get message properties, i.e. size and type

OWA weaknesses compared to Kerio:

- Unable to change access/delegation rights
- Can't move/copy/delete all items in a folder
- Can't mark all as read
- Can't mark as unread
- No Spam training
- Can't forward as attachment
- Address book only has one view

OWA Light is even weaker:

- Poor interface for viewing folders
- Calendar view is day only
- No access to server-side rules
- No message preview pane
- Can't view message source
- No item count shown
- Flags not shown

I assume there are "hidden" features I have not found. For example, Kerio WebMail puts up meeting reminders, does OWA?

Again, I'd really appreciate hearing from others with experience using both products.

Thanks,

Will Mayall

One thing that is nice with OWA for IE is that you can "ActiveSync" over the wire (USB) with a Windows Mobile device using OWA. There is no need for Outlook to be installed. Also, when we bought our Exchange licenses we also got licenses for Outlook included in the price. This included the license for our users to install both at home and at work. You can connect Outlook up directly to OWA over http/https without having to open up IMAP or POP3 to your backend server. http://support.microsoft.com/kb/833401 Exchange 2007 support automatic setup of your users mail client in Outlook 2007. You setup a DNS entry and some settings on a http page on the LAN. When users open up Outlook for the first time on an AD their Outlook is automatically setup for them. Probably not a benefit of OWA though.

The costs kept us from going with Exchange. We already had Outlook licensed in Office, so that wasn't a money saver.

Nixs, thanks for listing some of the advantages of OWA/Exchange. It's really difficult to discover them all.

Is OWA's access to shared items like folder, contacts, and calendars really as bad as it seems?

The documentation I find says:

1. Log into your OWA account.
2. Add the following to the URL:

/user<_a.t_>domain.com/?cmd=contents&f=calendar

WOW! That is horrible compared to Kerio webmail.

Not only that, but I have not been able to get it to work with the hosted Exchange service I'm evaluating.

Am I misunderstanding something?

You should compare OWA "light" to KMS "mini" Webmail mode. Anyhow, I see a big disadvantage in OWA: The full version only works in IE. Firefox, Safari and Opera users need to use the light version.

Even if your company only uses IE, if you need to access your mail from an Internet cafe, you might need support for a different browser, or if you have a Mac at home, you could only use the light version.

That would be a show stopper for me.

Yes, the comparison I've done finds that Kerio Webmail is more powerful than OWA and much more powerful than OWA Light. Many of our users are Mac users and would be therefore using OWA Light.

Thanks for the feedback.

Just pointing this out for comparison;

The Mac does have some Exchange support and Webdav support;
http://www.appleinsider.com/articles/07/11/19/road_to_mac_of fice_2008_entourage_08_vs_mail_3_0_and_ical_3_0.html&pag e=2

The article is pretty good about knocking the Mac product versus the Windows product. As I understand it you can have your OWA in the DMZ and point your remote Entourage users to the webdav running on the OWA in the DMZ.

That was one tough cookie to swallow for me with Kerio KMS. I have to allow direct connections from the Internet to my KMS Windows server. I'd really like to place the Internet facing portion of this in the DMZ.

Again, we selected KMS over Exchange. It was a cost versus feature question, and KMS made more sense for us.
