Activesync Email Client For Mac

Outlook for Mac and not syncing Hi everyone, looks cool but ironically Mac users that purchased and use Outlook2011 as email client don’t stand a chance to have a decent email service. Exchange ActiveSync will only work on mobile devices, tablets and Outlook 2013. To use an Exchange account with Mac Mail, you'll actually need Exchange Web Services. When you have EWS enabled, you can follow these steps to configure it with Mac Mail: Configure Apple Mail for Exchange Web Services. If you have Snow Leopard 10.6.x on your Mac, the built in Mail, iCal and Address Book support Active sync. Exchange 2007/2010 only. Else you'll have to spring for Office 2011 Business Edition to obtain Outlook 2011. Dec 31, 2013  Best Microsoft Exchange client application for OSX? Discussion in 'Mac Apps and Mac App Store' started by mathcolo, May 14. (apparently because of its lack of support for Exchange ActiveSync). So, that said, what do you all think is the best mail client for OSX that supports Exchange+push these days, and is.

Everyone manages their email a little differently, so picking one client that works best for everyone is tough. However, we've picked Thunderbird as our favorite desktop email client due to its numerous features and add-on capabilities.

Where It Excels

Out of the box, Thunderbird doesn't necessarily blow other mail clients out of the water. It does have some really nice built-in features, like tabbed browsing, multiple layouts, a pseudo-conversation view, and super easy account adding. However, Thunderbird's true awesomeness lies in its add-on capability. With Thunderbird's big add-on library, you can tweak Thunderbird to fit a lot of specific needs. For example, you can import address books, import Outlook PST files, or even skin it to look like Apple Mail. You can really tweak your experience, which is great.

Where It Falls Short

Thunderbird is actually a pretty great client, and it's hard to say it has 'downsides'—it just isn't quite as powerful in certain areas as other clients. For example, if you need Exchange support, you'll have to look to an official Microsoft offering. If you want seriously powerful search and attachment organization tools, Postbox might be more up your alley. Thunderbird is a great all-around client, though, and will fit almost everyone's needs—especially with the availability of so many add-ons that let you tweak your experience.

The Competition

The main competition to Thunderbird are Microsoft's two email clients, Windows Live Mail and Microsoft Outlook. If you use Exchange, you'll probably need one of these. Windows Live Mail is actually a pretty good client, and has a lot of the same features as Thunderbird, like conversation views, as well as some nice Windows integration. It doesn't have the awesome add-on support that Thunderbird does, however. Outlook is a very full-featured email and calendar client that is pretty powerful, and useful for organizing a lot more than email. It does, however, come with a hefty price tag.


If you like Thunderbird but just want something a bit more powerful, Postbox is a really great option. Postbox takes Thunderbird's open source code and builds a very powerful client on top of it, including more advanced search, some serious attachment organization features, and other features that stress making email faster and easier. Its only downside is that it costs money, though it's now only $10—which is well worth it for what you get.

These aren't the only mail clients on Windows, but they're by far the most popular, and you're bound to find something that fits your needs with these few options. And, of course, there's always the option of webmail, too—after all, Gmail is still one of the best mail clients out there.
