Outlook Mobile Gets a New Architecture

Posted on by


Microsoft has simplified the synchronization architecture used to connect Outlook mobile clients to Exchange. The new approach sets the scene for some new functionality, like support for S/MIME and access to shared mailboxes. It’s all good and it marks the continued progress of Outlook mobile since the Acompli acquisition in 2014.

Choosing the Best Mobile Office 365 Email Client

Posted on by

Companies that move to Office 365 have to decide what mobile email client to use. A native client that uses Exchange ActiveSync (EAS) or Outlook? In the past, the best choice was probably something like the iOS mail app. Now, Outlook is the focus of Microsoft’s mobile efforts and it’s where all the new functionality appears. EAS is still valuable, just less so than it was before.

iOS 11 and Exchange 2016/Online: Not Kissing Cousins

Posted on by

Apple released iOS 11 and found that the mail app cannot connect to Exchange Online or Exchange 2016. It’s all to do with HTTP2 connections. Apple tries to connect via ActiveSync but doesn’t do so the way that Exchange likes, or something like that. In any case, maybe now’s the time to consider Outlook for iOS.

Office 365 Forced Sign-Out

Office 365 allows you to block a user when necessary, as when someone is leaving the organization. You can also initiate a forced sign-out, but the option to do so is buried in the user’s OneDrive for Business settings, which seems like a logical place to find it!

Why Contacts Are a Problem for the Outlook Apps

Posted on by

My transition to an iPhone is fine and I have mastered Outlook for iOS. That is, except for Contacts, which are a problem because Outlook must obey Apple’s rules. And I won’t even discuss searching.

Safety Tips Inserted by Exchange Online Protection Make Email Safer

Posted on by

safetylinks

Microsoft is introducing safety tips to Office 365 to highlight bad or suspicious email that might tempt users to do things that they shouldn’t. The initiative is good and valuable, but it rather loses some of its gloss because not all safety tips are exposed in Outlook. However, Microsoft is making sure that mobile and other clients see safety tips, even if not in the same interactive manner as is possible with OWA.

Office 365 Hero

The world of Office 365 is ever-changing. This week my attention was distracted by the inability of the Admin Center to report unlicensed accounts, a Watson dump in an ActiveSync cmdlet, some interesting data about the number of Office 365 users affected by outages as revealed through an API, and more odd entries in the Audit Log. Thankfully Ignite is next week and nothing will happen.

By the time Microsoft Ignite happens in September 2016, the Outlook app for iOS and Android will have an all-Microsoft infrastructure. The Amazon-based cache is being replaced by a new architecture that is shared by Exchange Online, Exchange on-premises and non-Microsoft email servers like Gmail. It’s a big change and it’s happening now.
