Migrating From Exchange Server 2003 to Office 365

If office 365 beheer are nevertheless running Exchange Server 2003, then you have to have to quickly track your Office 365 migration, since Exchange 2003 stopped becoming supported by Microsoft in 2014. What’s additional, most Exchange Server 2003 systems are operating on Windows Server 2003 and this will also no longer be supported by Microsoft after June 2015. These two events mean your program will be increasingly open to external hacker attacks as safety breaches are no longer becoming fixed by Windows updates.

In addition, unless you have moved your server to a virtual environment sometime more than the final handful of years, it is really likely that your physical file server is also out of warranty, operating slowly, nearing its disk capacity and starting to suffer reliability challenges.

Migration from Exchange 2003 to Workplace 365 can still be safely completed, however there is normally an added issue to be overcome concerning Microsoft Outlook. Lots of organizations that are running Exchange 2003 are also running Office 2003. The great news is that moving to Workplace 365 presents a excellent opportunity to also replace Workplace 2003 by picking an Office 365 strategy that incorporates Office 2013 – for instance the Workplace 365 Organization Premium strategy.

The terrible news is you have a chicken and egg scenario simply because Office 2003 in general – and Outlook 2003 in specific – does not work with Office 365. This suggests that through the migration process you have to make a decision between upgrading your e mail system initially, and then not being capable to access it until you have updated all the computer systems to a later version of Workplace (at least office 2007). Or, you upgrade all the computers to a newer version of Office 1st, and then do the migration of Exchange Server to Office 365.


Whichever approach you select, there will be a period of time when users are stuck in no man’s land – they will not be in a position to access their e mail server from their version of Outlook. So a decision will need to be created – is it finest to upgrade Office very first, or is it greatest to upgrade the email server very first? True world knowledge shows that it is greatest in every single scenario to upgrade to Office 365 initial and then upgrade Office 2003 customers to Office 2013. Here’s two hypothetical examples to prove this point:

Company A has 20 staff with 19 customers running Outlook 2010 on their computer systems and with only a single user running Outlook 2003. It would be finest to migrate the email server to Workplace 365 initially, since only the a single user won’t be capable to access the new e-mail server until their version of Workplace gets upgraded. And it really should take only an hour or so to get that user’s personal computer upgraded to Workplace 2013.

Firm B also has 20 employees, but in their case 19 customers are on Workplace 2003 and only one is on say Workplace 2010. At very first glance this seems like a issue – if the Exchange 2003 Server is migrated to Office 365 initially then the 19 staff won’t be capable to access their emails till the computer systems have Office 2013 installed. And conversely, if the 19 computers are updated to Office 2013 1st, they will not be capable to access their emails till the Office 365 migration procedure has been completed. Fortunately, in this case there is a incredibly good interim option – users can make use of OWA (Outlook Internet Access) to access their emails via the browser till their computers are updated to Office 2013. Certainly, it will also be feasible for them to now have access to Office 365 e mail on a variety of smartphones and tablets they could currently have like iPhones, iPads, Windows mobile devices and Android devices.

Performing migrations to Office 365 from later versions of Exchange are a lot less difficult to action, but with a well-made scoping plan that considers the implications of old versions of Office, the Exchange 2003 migration process can still be performed in a timely and cost-powerful style.

It may well properly be that the finest way to assure your organization of a effective Office 365 migration from Exchange 2003 is to use the solutions of a Microsoft Companion that has Office 365 certifications and actual-world practical experience in performing Workplace 365 migrations.
