With the ever-changing business and technology landscape, staying current with your software is imperative.  Microsoft has announced that older versions of Outlook such as Outlook 2007 and 2010 are incompatible with the following major upcoming service changes.   

  • Support for basic authentication is ending to increase the security of Microsoft 365 by relying on modern authentication protocols, which are not only more secure but also provide compliance and policy controls to help you manage your data.  
  • To improve data transfer between Exchange Online and Outlook Client, Microsoft is working on transitioning to a new protocol ( HTTP/2). This new protocol can provide multiplexing capabilities and better performance over the internet, giving a better user experience with faster access to your Outlook and Microsoft 365 with less delay.   

It can be a challenge to stay current with hardware or software requirements on servers. With that in mind, there are many reasons why staying current is a good idea:  

  • Security fixes will protect your devices against known vulnerabilities: With many companies running with a hybrid or full remote workforce, cyber security is ever important.   
  • Reliability – over the last five years Microsoft has eliminated 75% of crashes in Outlook!  
  • Updated versions have all the coolest new features to make your life easier! 

How does this affect you? 

If you are running one of the above Outlook and Office clients, they will be unable to connect to Microsoft 365 Services. We and Microsoft recommend switching to the subscription model of Office 365 or Microsoft 365, which provides always-up-to-date client software.  

If you are affected by this reach out to us today and we will help you get your subscription sorted.
