Understanding Exchange Online

Exchange Online is the software as a service (SaaS) platform hosted by Microsoft Azure and available on a subscription basis via Office 365. By allowing you to use servers, mailboxes and other email infrastructure hosted at cloud, Exchange Online can significantly reduce out-of-pocket expenses and management hassles. This is especially attractive to small and medium-sized businesses with minimal IT resources or in-house technical expertise.

The migration to Exchange Online can be relatively simple or extremely complex. It depends heavily on your current messaging environment and functional requirements.

Lambert Consulting can migrate all the data you have from your traditional emails, calendars and contacts to email signature blocks, rules and all your various calendar permissions. We make the transformation fromExchange Server to Exchange Online simple and risk-free. On top of that, we can work on migrations for every version ofExchange Microsoft ever deployed.

3 key attributes ofExchange Online that you can't afford to miss.

1. Serious return on investment

Switching to Exchange Online can actually save your organization a lot of money. Mail servers represent huge infrastructure and overhead costs requiring ongoing maintenance and upgrades. There is the maintenance, replacement, and utility bills for the servers that come with running and operating them.

The migration to Exchange Online puts an end to all that. Instead, in exchange for the subscription price, all your server problems are solved for you. No more server maintenance or installing new updates.

2. Security

Perhaps the most important benefitExchange brings to your business is its incredible security. Microsoft Office 365 Secure Productive Enterprise brings together a suite of essential business applications with integrated collaboration, mobility and intelligence around an umbrella of security, compliance and trust.

Microsoft has spent literally billions of dollars onExchange Online's data security offering, which ensures that your email is more secure in Microsoft's protected cloud than in your own on-premises server.

Exchange is also compliant with all major compliance standards such as ISO 27001, HIPAA and FISMA.

3. Performance

When it comes to simplicity, ease of use and enhanced functionality, no other messaging system can match Exchange Online. Exchange Online provides fast, intuitive and convenient email controls. It has intelligent searches that allow you to quickly find emails in your system. Searches are performed by keyword, author or date, allowing for fast and accurate search results.

While personal email and other systems can be bombarded with dangerous junk mail and spam before you know it. Exchange Online's spam filter ensures that only legitimate emails will arrive in your inbox.

Exchange Online is accessible on platforms such as mobiles and tablets, while being fully integrated with Microsoft's cloud service. Wherever you have an Internet connection, you can access your e-mails.

Hybrid strategy ofExchange

A hybrid deployment is a combination of on-premises applications or data and cloud based services. For example, hybrid solutions Exchange may include using an on-premises Exchange server and Exchange Online in Office 365 . Whether you move to Exchange Online incrementally or keep some users' mailboxes on-premises and others in cloud, you can use a hybrid deployment Exchange to achieve your goals.

In many cases, an organization will want to establish a hybrid environment that supports both local and cloud based mailboxes. This may be preferable to a 100% cloud model to comply with regulatory or business standards, enhance security, improve availability and provide management flexibility.

In addition, best practices often dictate the creation of hybrid configurations as a temporary step in migration safely moving from an on-premises Exchange deployment to Exchange Online.

Email flow, which is the end-to-end path that messages travel from sender to recipient, can also add complexity. For example, the use of third-party email filtering services based on cloud or multifunctional desktop devices that generate and receive email can affect how you integrate Exchange Online into your email environment.
