Hi,

We currently use Exchange 2003 and are looking to upgrade our e-mail system to a cloud based system, namely Google Apps for business or Office 365. 

We have around 75% of the company on Office 2007 and need to know how long this version of office will be supported to work with Office 365. I understand that there is already limited functionality in comparison to Office 2010 but none of this affects our business.

I have found that there are two levels of support, mainstream and extended. Will Office 2007 continue to be supported with Office 365 until the end of mainstream or extended support?

Kind Regards

Haydn
