Prepare For Microsoft Outlook & Office 365 Changing
August 31, 2017

Microsoft made a recent announcement outlining a change in the way Office 365 and Exchange Online communicates with Outlook that could see many unable to access their inboxes. Here we look at how to safeguard your access and your data.

With Outlook 2007, 2010, and 2013 set to retire and thus no longer being supported by Office 365, anyone not already running the 2016 version needs to make plans to upgrade before the changes are rolled out.

The benefits of upgrading to Outlook 2016 make this requirement an attractive inevitability, with enhanced licensing options, including Office 365 ProPlus, Business Premium and E3 for example, providing improvements to productivity and a commitment to addressing future changes as they are rolled out.

Planning a migration? Unfortunately, you’re not necessarily covered. If you’re planning a migration to Office 365 in the weeks prior to 31st October it’s worth noting that you may initially be able to connect but once the update takes effect your connection will be broken and you will need to upgrade regardless.

First Steps

Not sure what you have? Follow the steps below to identify your version and/or build number.

Keep in mind that your organisation might be running multiple versions of Outlook so it’s worth getting every member of your team to run the exercise below and report back to you. This will help you and your infrastructure specialist formulate an efficient upgrade plan that’s specific to your needs.
  • In your Outlook, navigate to the top left-hand corner and click on File.

  • In the blue column on the left select Office Account.
Alternatively, if you don't have ‘Office Account’, locate Help. Here you will see the product version on the right-hand side of the page.
  • On the right-hand side of the page you will find the version and build number under Product Information.




Outlook 2013

After Microsoft’s October deadline you may still be able to connect if you have updates installed that meet or exceed build number 15.0.4779.1002.

Outlook 2010

Post October you may still be able to connect if you have sufficient updates implemented that meet or exceed build number 14.0.7164.5002, however it is important to note that mainstream support for the 2010 version will be discontinued so planning an upgrade should still be a priority.

Outlook 2007

Come October 31st 2017 you will not be able to connect to Office 365 and will require a comprehensive upgrade.

Back-Up Strategy

Once you have identified the version(s) in operation you need to review your Office 365 backup strategy.

Etain’s Head of Microsoft Practice, Kyle Downey advises “make a comprehensive review of these strategies a priority. Are your current implementations, policies and practices robust enough to protect mailboxes in the event of a malicious attack? How well equipped are you to deal with accidental deletion?”

Look closely at where and when you are backing up. If it’s in the Cloud we advise upwards of two-three times per day. Not only will this keep your data recovery as close to ‘most recent’ as possible, it will reduce potential support costs in the event of a major system-down.


Plan To Upgrade

Once you are equipped with the bigger picture on where your organisation sits in relation versioning and a revised back-up strategy, actually implementing an upgrade before the Outlook 2016 deadline (31/10/2017) is essential. Unfortunately, you will not be able to acquire support for retired versions, and any vendor purporting to do so is, and taking your money for the pleasure, is not to be engaged.
