I’ve been managing a couple Kerio servers for a few years. Overall, I am happy with them and have experienced only a few problems that I am sure are related to the Kerio software. In particular, the administration of the servers is really nice.

We are a Mac shop, both for the servers and the users. The users use Microsoft Entourage 2008 and connect as Exchange clients. Everyone’s software is up to date.

Some of the users are intense email users and receive hundreds of emails a day, have accumulated 5-10GB of email, and have 10k+ emails in multiple folders. All of the intense users (including myself) have experienced corruption in their local Entourage databases where Entourage asks you to rebuild the db.

Generally, rebuilding an Entourage db has gone OK but is very time-consuming. For one very important user, the db corruption and rebuild has caused horrible problems where large numbers of messages disappear both locally and on the server. I’ve been able to recover the messages but it is not fun.

When communicating with Microsoft, a few things become apparent:

- Corruption of large active databases is expected.

- Although Entourage tells you to rebuild - don’t. Instead, create a new identity and retrieve the data from the server.

- The number of messages is apparently a bigger issue than the db size.

Knowing the above, I now have people not rebuild but instead create a new identity. Unfortunately, there is a perception that the server is involved in the problem because it is not a “real” Exchange server. Although I don’t think this is the case, I have no way to prove it.

Management decided we should move to a hosted Exchange service. I continue to try to convince them that a move to another server has its own risks and may not solve the issues we have.

I’d appreciate any feedback from this forum:

- Have you had any experiences similar to the above?

- Do you have any experience with hosted Exchange?

- Will a hosted Exchange service be more or less reliable?

- What is it like to administer a hosted Exchange account?

Although I’d like to keep using the Kerio server, I’m primarily interested in providing the best service for the users. If that means moving to hosted Exchange, so be it. But I’d like to have some evidence that the issues will be solved instead of simply trying it to see if it helps.

Thanks!

Entourage sucks. Always has, always will. You will have the same problems with Exchange that you're having with Kerio.

I agree that Entourage has issues. Unfortunately, there is no other realistic option for a collaborative email client on the Mac.

Does anyone have recommendations for good email archiving systems? Sonian.net looks good.

It is not only Entourage. We are using Outlook 2007 on MS Exchange 2007. We are using Offline mode, meaning mails are copied to the local OST file and people can read mails even if the Exchange Server is offline.

Any OST file bigger than 2GB-4GB can get a nightmare and can get corrupted. It doesn't matter if you use hosted Exchange, local Exchange or Kerio Mail Server. The same problem exists with PST files.

So, you won't solve your problems by going to hosted Exchange.

What we have done: We have limited all user mailboxes to a maximum of 1GB. Users should understand that the mail system is not a file repository! Regular cleanup keeps the system healthy.

Agree with the prior poster. I use the iMail with KMS on my Mac and that gets corrupted from time to time. Though I've never noticed a rebuild loosing any e-mails. I had about 6GB of e-mail, though recently archived 3GB offline.

I have had to fix over the years hundreds of corrupt PST files using POP3, IMAP, and KMS.

1and1 has a hosted Exchange solution you can start out at around $7/mo per user and you can start with just 1 user. That's what I did. After a few months the trial user ended up rolling back to KMS.

Great feedback.

Why did the user switch back to KMS?

It sounds like the problems tend to be the clients and not the server. That has been my experience but I have little experience with Outlook.

Thanks,

It'd been a while that we did this, so I'm not recalling all the details. From what I recall the KMS issues the user was having got resolved, plus having GB connectivity to KMS with KOC is a lot better than having shared 1.5Mb to outsourced Exchange. (Our KMS has two 1GB NIC's teamed, user has 1 GB NIC and GB switch.)
