I had a couple of questions from users still using Outlook 2007, wondering if they would be able to use it with Office 365 Exchange Online.
Yes! Until October 31, 2017, as long as all Outlook 2007 updates are installed, you can use Outlook 2007 to connect to Office 365 Exchange Online or the new Outlook.com (hosted on Office 365 infrastructure) as a Microsoft Exchange account.
You’ll obviously have a better experience if you are using Outlook 2013 or Outlook 2016, and you won’t be able to use the newer Exchange 2016 features that are available to Outlook 2013 and Outlook 2016 users, but the important things - your email, calendar, contacts, and tasks - will sync and the features you are familiar with will continue to work.
Users will need to upgrade by October 31 2017, when RPC over HTTPS protocol is disabled for Office 365 and Outlook.com accounts, if they want to continue to sync calendar, contacts, tasks, and notes with Outlook. For more information, see Deprecation of RPC over HTTP in Office 365 (and Outlook.com).
Another important date is October 10, 2017, which marks the end of the Extended support period. While this won’t affect ordinary users and the Office applications will continue to work, it does mean that security updates are unlikely to continue past that date.

You can of course continue use Outlook 2007 as a POP or IMAP client to Exchange on 365 - not ideal but it will work for the default folders.
Correct, but you will lose calendar & contact sync.
I have a customer that still has about 25 users using Outlook 2007. Since it has been 18 months since you posted this, is Outlook 2007 still viable for use with Office 365? I am really trying to get them to upgrade just for the security of the newer versions, but may have to stay with 2007 for the time being until i can get them fully migrated to Office 365.
Thanks!
Thanks for reminding me I need to update this article. Outlook 2007 will no longer work with Office 365 (as an Exchange client) after October 31 2017, so they have about 6 months to upgrade.
The problem with Outlook 2007 and Exchange EWS is the calendar. All events that you enter in Outlook for April are wrong by one hour if you look them up in Exchange. I found this out when I connected the new Oulook-Mail based on Exchange EWS and looked at calendar events in April (after daylight saving time change). Birthdays in the summer half are also now two days events.

What time zone is your outlook.com set to use? Log into outlook.com and check your account settings.
Hi Diane,
I figured out the solution: in Outlook2007, options, settings, calendar option, time zone, actual windoows timezone under the timezone there is a switch: automatically switch daylight savingtime in windows.
This did it. Now all the Exchange Calendar entries are correct but unfortunately the local calendar entries are screwed up. and needed to be fixed for daylight saving time.
Thanks for the update.
