We are also having random sync issues with o365. Its actually incredibly frustrating because it will work flawlessly for weeks, then magically stops. Its been the cause of multiple double books and I've had enough. We actually moved FROM gapps to o365 because it wasn't great either. Now its worse, but haven't been advised to move back to gapps. That is not going to happen. I'll move away from RS before I go back to gapps.

RS advised we should move (back) to Gapps... No thanks!

Only the first instance of a recurring calendar event is syncing with the repairshopr calendar. We need all of our calendar events to sync for the repairshopr calendar to be useful.

We are having issues with 2-way breaking randomly - also reoccurring entries don't sync to RS.
We need this to work to be able to use the Appointment Booking module - we put unavailable times and holidays in O365 calendar

I've just added this to our repairshopr trial, sync to office 365 seems to work well but not sync from 365 to rsr

I'll be happy to be a Beta...How do I get started?

I have hosted exchange via messagestream.com - will this work?

Feedback to everyone: One-way sync (as described above) is working great! Appointments made in RS seamlessly add to my 365 calendar, and editing/deleting sync's quickly. Notes are a little crude, but location and title are great. Really excited for two-way, as I'd like to see/compare my current schedule and free time against what I have available for appointments. In any case, this is going to be amazing for on-site/remote techs!

We would be happy to test this as well.

I would like to test as well!

I too would be ecstatic to beta test this feature

happy to test on a multi tenancy Exchange 2013 server if that's supported (or are you going to support 365 only?)

Happy to help here also

I would be happy to beta test this

OMG, I forgot to ask until now - @Troy:

Is this integration going to be a sync for Office 365 as a WHOLE, or JUST calendars? I am still dying to have our RS customer database sync with my 365 contacts, too. Is this part of the same sync system? :D

I'd love to beta test this feature. Just what I've been waiting for.

OH. MY. GOSH. 19 months of waiting and it's finally happening! AHHHH!!!!!! Since my original post in Jan 2014, we've now switched from on-premise Exchange to Hosted 365, too.

Great news as we like the look of this app and really need the office 365 integration.

+3 for hosted exchange support :)

FYI - many others are doing this by asking you for your exchange login, storing that information, and logging in as you using something like an IMAP client protocol.

I am not going to implement that method. Something feels wrong about storing your AD login.

On the plus side, we've now seen some apps using the REST APIs in the wild (properly) and plan to take another look at this very soon and see what has changed, or if we missed something.

(2 legged OAuth flow to just have permissions to your calendar, vs being able to login to your domain accounts)
