Big news from today’s Windows 10 announcement: Microsoft will be shipping a “universal” version of Outlook that works on Windows tablets, phones, and PCs. This is a really interesting move, and not something I expected based on the existence of OWA for Devices (MOWA) on iOS and Android. The universal Outlook uses the universal version of Word as its editing engine, a huge plus because it delivers all the rich formatting tools available on Windows PCs (and which are still, sadly, missing from Mac Outlook, hint hint), and during the demo, Joe Belfiore showed a fluid touch-based interface that nonetheless preserved much of the look and feel of Outlook and OWA.
This announcement raises a lot of interesting questions, though. A partial list, just off the top of my head… (and a disclaimer: I haven’t seen any preview versions of Office 16 so perhaps these are naive questions that have all been well dealt with in the code)
- Is this new version of Outlook a replacement for, or a complement to, the existing rich Outlook client? In other words, will it be able to do everything that I can do with Outlook 2013 on a Surface Pro 3? If not, what will they leave out?
- Will this app replace the native WP calendar and contacts app? I’d guess not, given that the People app got a lot of play in today’s announcement.
- Outlook’s resource requirements would seem to be a poor fit for phones and low-end tablets. I’d imagine that we’ll have sync controls similar to what exist on WP8.1 to allow users to sync a certain amount, but not necessarily all, of their mail, but it’s going to take a lot of optimization to provide acceptable performance on these devices.
- Will this version of Outlook support on-premises servers? If so, that means it probably won’t rely on MAPI over HTTPS, which isn’t widely deployed. But it’s hard to imagine Outlook built completely on Exchange Web Services.
- Will the universal Outlook team match the slow release cadence of desktop Office or the faster cadence of, say, the Lync mobile clients? One of the nicest features of OWA for Devices is that new OWA/Office 365 features (such as Clutter and the People view) just automatically show up in MOWA because it’s essentially a container for OWA views. How will the universal Outlook team bake in support for new features as Exchange and Office 365 ship them?
- Will Exchange ActiveSync-specific features (especially remote device wipe) be included in this version of Outlook? They aren’t included in the existing Outlook family, of course.
- If the answer is “no, but you can use InTune or Office 365 MDM”, that’s going to displease a lot of existing users. On the other hand, you can’t remotely wipe a desktop Office installation, something which has led several of my customers to block Outlook Anywhere so that people can’t easily use Outlook from personal machines.
- If the answer is “yes”, then it will be fascinating to see how Outlook interacts with native data such as contacts stored on the device.
- What does this mean for OWA for Devices? I’d guess that we won’t see Outlook for iOS and Android, but I wouldn’t necessarily rule it out. Maybe we’re headed back to the days of yore, where the premium clients run on Microsoft operating systems, with a sort of best-effort client set for competitors.
- Is this the logical vehicle for incorporating the technology Microsoft acquired from Acompli? Or is that being baked in somewhere else?
- When can I get a Surface Hub?
Given the upcoming availability of previews for Windows 10 for phones, I suppose we’ll get the answers to these questions soon.
