We’ve helped countless organisations — from fast-moving nonprofits to professional services firms — successfully transition to the cloud with Microsoft 365 (formerly Office 365). Across industries, the shift to Microsoft 365 has empowered teams to collaborate more effectively, reduce risk, and eliminate the headaches of on-premise infrastructure.
Through these migrations, we’ve been asked the same core questions time and time again. So, whether you’re just starting to explore your options or already planning your move, here are the five most commonly asked questions about Microsoft 365 migration — and our expert answers.
1. Is Microsoft 365 (formerly Office 365) secure, particularly compared to having a server in our own office?
Using the cloud-based Microsoft 365 is much safer than storing your data on your on-premise server, both physically and in regards to attack.
With Microsoft 365, your data is stored in a secure, fully redundant data centre based in Australia.
With your on-premise server, it’s likely stored in the corner of your office and is vulnerable to break-in and theft. It’s also unlikely to be built with as much redundancy as the servers in Microsoft’s data centres, so is more vulnerable to hardware failure.
In terms of cyber-attack, most small businesses use entry-level routers and firewalls that offer minimal protection. Microsoft’s data centres use state-of-the-art hardware that is fully updated with patches to keep your data safe.
Microsoft 365 also has many security features that can be switched on, like two-factor authentication and Advanced Threat Protection. These features will help mitigate against malicious attacks.
It also comes with Secure Score – a feature that recommends actions you can take on your setup to improve security. It enhances security from the default settings.
2. How much storage do I get with Microsoft 365? Will I have enough space?
There are several types of storage with Microsoft 365 (formerly Office 365), each with their own limits.
Mailbox storage
The Microsoft 365 Business Standard (formerly Office 365 Business Premium) and Microsoft 365 Business Basic licences include 50GB of mailbox storage per user.
Enterprise licences (such as Microsoft 365 E3 and E5) include 100GB plus an unlimited online archive, providing effectively unlimited email storage.
File storage
With OneDrive for Business, each user is allocated 1TB of storage for personal files. For team files, Sharepoint offers 1TB of storage per organisation plus 10Gb of storage per licence.
3. How can I access my files if they are in the cloud?
Before you can access your files, you need firstly to be authenticated. After that, there are a few different ways you can access your cloud-based files.
Web browser
You can access your files via the web browser from any computer with web access.
Synchronise your files to your computer
Synchronising your files allows you to access them from your local hard drive. They’re synchronised on the fly so they only get downloaded when you access them. This saves on save hard drive space and bandwidth.
4. Will my employees have to do anything differently when we move to Microsoft 365?
For email, there will be no difference for your users between using an on-premise or a cloud server.
For file access, there will be some difference in the way they access files. If they choose to access files via the web, the process will be different. If they use synchronised files, the process will be similar to using a networked drive of the normal on-premise server.
5. Which subscription should I choose and what is included in each one?
Choosing the right Microsoft 365 plan depends on the size of your organisation and the features you need. Microsoft offers plans under both Business and Enterprise tiers to suit different business requirements.
