Hello

I'm technical assistant for a company with about 60 persons.
At the main building, let's say site A are most of them 40 persons.
There are also 3 other sites, let's say B,C and D.
We are planning to install a mail server which will serve all sites.
At this time all sites are receiving email through ISP pop3 accounts via outlook.
What we want is a centralized email server whch can do this tasks:

1. Have a central email location for all users.
2. Backup all mails through backing up mail server's database.
3. Access from anywhere anytime.
4. Blackberry synchronization.
5. Maximum availability.
6. cost effective.

Right now alla sites communicate with the main site through adsl lines and hardware IPsec VPNs.We do this beacause we have an ERP Application which all sites access through Terminal Services.
As i can see there many options in the market how to achieve this.
I have concluded to these: •xchange Server 2007,Kerio Mail Server and Zimbra.
Although i have some questions:

1. Is it beter to have the server inside the company with 1 or 2 adsl lines,ups,backup device,antivirus or have it hosted at a datacenter?

2. In case it is inside the company can i configure it with some kind of fail over in case 1 adsl line drops to the other one?

3. Wil adsl lines be fast enough to server the users on the other sites?Except of using web interface can they use Outlook to synchronize the mails?

4. If we put the server on a datacenter will it be better for all above?

thank you for any answers and sorry for my bad english.

Hi,

My company has a very similar setup as your where we have one main office with several satellite offices. The main office has around 50 users while the rest of the 50 or so users are scattered around the satellite offices which are connected via hardware VPN.

My management and I actually prefer running our mail server because we are a growing company and would like to be able to manage as much as our own infrastructure as possible for future expansion. Always have 2 data lines from different providers for continuous availability. The fail over option can be configured on your hardware firewall or router. We use FIOS as the primary which is blazing fast and a cable as fail over.

We have our own file server along with networked virus solution anyways so new email servers arenot a problem. But if your company doesn't utilize servers of any sort and don't have a good technical team/staff, its better to go for the hosted service. Also, you can expect quite a upfront charge for the servers and software if you going with Exchange 2007/2010. Our tab was around 39K for 100 users. Hosted service would probably be around $10 per user per month. Still we would prefer over self hosting with all the functionality and control.

Thank you for your answer.
Just a question.How do your satellite offices access the mail server? via OWA or Outlook?
I need to use Outlook with mapi and not POP3 will it be fast enough?

All workstations in our satellite office access emails through Outlook connected via Exchange directly. Since your sites are connected by hardware VPN as well, there is no need for MAPI or POP3.
