Things to consider before migrating to office 365

Many SMEs have looked at Microsoft’s public cloud platform, commonly known as Office 365 as a simple cost effective route to cloud computing, but when compared to private cloud options, is the initial low cost all it seems?

Depending on the business package you choose, the short-term cost of Office 365 can be compelling but the total cost of ownership (TCO) can often mean it is more expensive and more time consuming than initial projections assume.

Below are some things your organisation should consider before making a decision.

Network and limits:

Microsoft 365 relies on your existing network and bandwidth. If your Internet provider goes down, then you lose access to your enterprise software and data. Microsoft does not control how you access the Internet and, therefore can’t provide any support. With a private cloud solution and leased line your business has direct access to your applications without being reliant on the internet. Plus even if you have a reliable and fast connection, some of Microsoft’s hosted offerings, such as SharePoint Online and Exchange, are throttled and have some fairly tight capacity limits. One example of this is the recipient rate limit, which is the number of recipients that can receive email (both inside and outside your organisation) in the span of a day. Also things like mailbox size and site collection quota can vary from between different subscriptions.

Data privacy:

For organisations working in data-sensitive sectors or regulated by compliance, such as legal, Office 365 has a major vulnerability; all your private business data will live on Microsoft’s servers. Microsoft’s servers aren’t located in the UK, the closest European datacentres are in Dublin and Amsterdam, however there’s no way of ensuring that your data will be completely stored within the EU, which means any e-mails, documents or key files stored in Microsoft’s cloud could be accessed by third parties. With private cloud sold by a specialist (rather than a re-seller) your data and applications are secure and can only be accessed by authorised personnel.

Limited flexibility:

Although one of the initial draws of Office 365 is its simplicity, you may find things become incredibly complicated once you attempt to integrate your MS Exchange with CRM systems, for instance, or try to configure your 365 to sync with other applications such as a CRM. In short, with 365 you could be faced with multiple restrictions if you try to manipulate what you’ve been given into what you actually need.


If you’re thinking of migrating to Office 365, you should carefully consider whether it’s the right choice for your business, especially if your organisation has one or more of the following requirements:

  • Direct support in the event of any network or service issues
  • Uncontended, un-restricted access to data and applications.
  • Secure data storage, including UK-based servers and a private on an unshared platform
  • Full control of your cloud network, with your own applications seamlessly integrated for easy access.
