What do I get with Office 365?

Office 365 is a powerful and comprehensive suite of services and tools which can help any business, whatever its size, to be more productive. Users are able to access emails, contacts, calendars and use a vast array of applications to improve collaboration and work more effectively. As a cloud-based productivity suite it is subject to regular updates and features from Microsoft so you’re always using the most up-to-date version.

There are three levels to Office 365 from a business perspective. The first is the core Office suite. This provides you with Excel spreadsheets, Word documents, PowerPoint presentations, Outlook for email and personal information management plus OneNote for gathering your notes and multi-user collaboration. This set of services is incredibly useful to any business, offering the opportunity to replace a disparate set of services that you might be using currently and replacing it with one highly useful set of tools and one cost centre.

The next level of services that Office 365 offers is a more specific set of tools focused on creating a shared workplace. These include:

SharePoint – a web-based collaborative platform that allows you to manage and share content within your business

Skype for Business – an application allowing video and voice conversations via different devices

Microsoft Teams – a unified communications platform that integrates workplace chat, video meetings, file storage and application management that will eventually replace Skype

OneDrive – has storage, sync and share, connecting you to all your work files and documents

Together these tools provide a powerful next step towards increased productivity and collaboration plus an extra competitive edge.

And then there’s a third level which is even more niche - a set of apps that enable even more creativity within the Office 365 suite:

Delve – displays useful information to the user from across Office 365 based on the work they’re doing

Flow – allows the automation of business processes via the creation of workflows and tasks based on certain triggers and actions

Forms – a tool to create surveys and quizzes

Sway – an alternative to PowerPoint that’s designed for creating visually appealing and professional presentations

Office 365 is a product that never stands still and is constantly being refreshed with more features and updates to help the modern business and, because it’s cloud-based, you will always be accessing the latest version. It can be installed on many machines giving you the ability to access a range of Office programs from multiple devices – surely the best option for any large or growing business. And the fact that you’re not having to pay a large cost upfront is a big bonus for having access to many features that you not use at first but might end up finding incredibly useful as your business develops and grows.

All of this is unified under the Office 365 banner with a single login, allowing users to collaborate with other members of their organisation and with other external organisations in a completely joined up manner.

How to Set Up Your Office 365 Account

When you’re ready to move your domain to the business version of Office 365 there are a number of steps to take. You’ll need a list of all the users that you want to add and create a plan for how you’re going to let them all know what their new login details are. If you plan on using Office 365 email then you’ll need to know where your domain is registered and have the sign-on information.

Then it’s a case of migrating your mail, setting up your online services such as Skype for Business, and changing your name servers so your domain provider can start re-routing your email.

There are many benefits to moving to Office 365 including:

  • 1TB of OneDrive for Business cloud storage per user
  • The latest online versions of Word, Excel, OneNote, Outlook, PowerPoint and Publisher.
  • Use of Sway to create interactive reports and presentations.
  • Single sign-on and synchronisation with Active Directory for managing users and permissions.
  • Guaranteed 5x9s uptime and proactive data monitoring and privacy protection.

How to Manage Your Office 365 Account

There are a number of Office 365 subscriptions available for business.

For smaller businesses:

Office 365 Business is best for organisations that need Office applications and cloud storage and sharing. It includes Outlook, Word, Excel, PowerPoint, OneNote and OneDrive storage. It doesn’t include business email.

Office 365 Business Premium is best for those organisations that need business email, Office applications and other business services. It has the same apps as above but also includes Exchange, SharePoint and Teams, allowing you to connect staff in different locations.

Both those business packages have a limit of 300 users whereas for enterprise organisations the packages have no limits: 

Office 365 ProPlus is the most basic enterprise package with Office apps Outlook, Word, Excel, PowerPoint, OneNote plus OneDrive storage. It doesn’t include business email.

As you move up from Enterprise E1 more services are included such as Exchange, SharePoint, Teams, Yammer and Stream. Enterprise E3 also includes security and compliance tools such as legal hold and data loss prevention. While with Enterprise E5 you get advanced personal and organisational analytics with MyAnalytics and Power BI Pro included as well as advanced audio conferencing and advanced threat protection.

The enterprise packages are available per user per month but on the basis of an annual commitment.  

Deciding on the right subscription for your business is not always straight forward. For instance if you’re not an enterprise you might head towards O365 Business Premium – however the number of extra features available in the Enterprise versions might be worth having if yours is a business that’s planning to expand. 

The best way to choose the right plan is to look at the features available, rather than the cost of the plan. If your strategy is about moving more services and tools into the cloud, then the higher tier plans might be your best option as long as you don’t incur unnecessary cost. You can always change your licences at a later date if you need to.

And in terms of security Office 365 supports an integrated approach to user authorisation, with a goal of single sign-on in mind, through the use of cloud-based authentication service Azure Active Directory.

Common Office 365 Issues

While moving to Office 365 can be a major plus for an organisation, there are a number of issues to consider before you decide to make the move. 


Microsoft owns Office 365 and hosts it in its own data centres which can only be accessed by Microsoft employees. So if you have an issue with Office 365 then you have to speak to the Microsoft Support team. This can take time. As a Microsoft Gold Partner iomart has access to a higher level of support so we can get answers quicker to any issues that crop up.


When new updates are issued they happen automatically whether you want to accept them or not. As a result a lot of companies look for a hybrid deployment via the desktop so they still have some ownership. iomart can advise on the best hybrid set up.


Just like any other cloud provider Microsoft does occasionally suffer from downtime so performance can be an issue. Even though Microsoft deals with this by giving service credits, if online collaboration is a must for your business, you should have a backup option just in case.   


Microsoft continues to invest heavily in security. To avoid security issues it’s important to monitor your deployments via the security center to check any suspicious behaviours and monitor your users. iomart has a team of dedicated Microsoft engineers ready to help.


Most of the services and apps in Office 365 are compliant with the main international industry and data regulations but not all of them are. Iomart can check these for you to ensure you are meeting the necessary requirements.


It’s not always easy to customise the apps in O365 for your organisation and updates brought in by Microsoft can often impact any existing customisations that have been made.


How to use Office 365 effectively can be a challenge because of the number of apps and services that are available that your business might never have used before. Migrating to Office 365 is moving your organisation to a different way of thinking so it’s important that your users are on board with it. You may need third party assistance to train staff in the new features and keep them updated on how to make efficient use of them. iomart’s dedicated Office 365 team can help you get the most out of your Office 365 deployment.
