We are looking at MBSO for the Exchange Online Services. I wanted to know if someone has done a migration from Exchange 2003 to MBSO and could share his/her experience.
Our organization has 2 OWA servers and 2 Exchange server (cluster). I would personally prefer to migrate to Exchange 2010 and keep the servers in the company but I have been told to look at the online service.
What are the downside of going to the cloud with Exchange? What can and can't be controlled? Limitation, incompatibilities? etc...
The biggest criticism of running cloud-based Exchange is that servers are accessed over the Internet. If your Internet connection fails, Exchange becomes inaccessible. If Exchange was deployed on premise, an Internet connection failure would prevent email from traveling in and out of the organization, but users could still send mail to each other. They could also use their calendars, view contacts, etc.
We pay per device not per user so that gives us the ability to create unlimited number of mailbox.
The number of devices will be going down (computer) but the number of mailboxes perhaps will stay the same or it will increase.
With EX cloud we will pay per mailbox about 5$.
With Exchange in the cloud you have to pay for the Outlook 2010.
If you run Exchange on-premise, how long will it be before you upgrade to a new version? At list 7 years
If you subscribe to a cloud-based deployment, will the service provider raise your rates over time?
Are there additional charges for bandwidth or for excessive storage?
And although a cloud-based Exchange Server deployment may simplify administration, it can actually complicate Active Directory administration. All versions of Exchange since Exchange 2000 Server have depended on Active Directory; the AD requirement doesn’t just disappear when you run Exchange in the cloud. Organizations with an on-premise Directory likely will perform directory synchronization to the cloud .
Exchange in the cloud also has an inherent lack of flexibility. If you have a third-party antivirus, antispam or Exchange management product that you want to use, for example, you’ll have to ditch that product when you move to the cloud.
