How Exchange's Recover Deleted Items option could be improved 5

Since the introduction of the first "dumpster" in Exchange 2000, users have been able to recover deleted items without asking an administrator to recover the data from a backup. Given the propensity of humans to make mistakes (like deleting an important message in error), the feature has proved to be invaluable over the last 15 years....More

Exchange says no to .NET Framework 4.6.1 1

The disclosure on the EHLO blog that Exchange on-premises servers will run into some known issues if .NET Framework 4.6.1 is installed might surprise some, especially because it has become a recommended update distributed by Windows Update, but it’s not really much of a shock....More

Office 365 Planner FAQ 2

Many questions followed my article introducing Office 365 Planner, so clearly I didn’t do such a good job explaining the topic. Here’s an attempt to do so in a question and answer format. If you have other questions, try asking them in the Planner group in Microsoft’s Office 365 Network. What is Office 365 Planner?...More

Yammer for all (whether you want it or not) 1

The news that Microsoft has decided to activate Yammer for “every eligible Office 365 tenant” warmed the very cockles of my heart, even if some doom-and-gloom was introduced by the notion that this might be a tactic to stop customers looking at Facebook at Work. I think not in this instance....More

Synchronizing user photos across Office 365 workloads isn't easy 3

One of those who read my post titled “Pretty Delve profiles need better synchronization” from last December came back with a question about how to manage user thumbnail photos across Office 365:...More

Microsoft fails to communicate over Exchange Online IMAP4 outage 3

A curious incident occurred in Exchange Online over the last week or so when some European users who connect to their mailboxes using the venerable IMAP4 protocol reported that they couldn’t receive new mail. There’s nothing particularly notable about a glitch occurring with a messaging protocol. After all, Exchange supports quite a few (MAPI, Exchange Web Services, ActiveSync, IMAP4, POP3, and SMTP) in order to be able to provide as wide a client choice as possible....More

New OneDrive for Business sync client much better but not perfect 1

On December 15, Microsoft announced that the next generation synchronization client for OneDrive for Business is now generally available. A preview of the new software had been available since September. Despite many requests, I never managed to get hold of the preview so I was quite happy when Microsoft released the new client, which is available for both Windows and Mac OS X 10.9 (and above)....More

Online protection the only way to go 4

Microsoft’s January 14 post “Leading the way in the fight against dangerous email threats” to the Office blog recalled the discussion that ensued in September 2012 after they announced the cancelation of their on-premises email protection products, including the Threat Management Gateway (TMG) and Forefront Protection for Exchange (FPE)....More

Why public folder compliance gets no respect 1

Microsoft’s July 2 announcement of a “compliance toolset” for public folders appears to have fallen flat in terms of the excitement generated in the Exchange community.  At least, I never hear anyone talking about it or receive any questions about why Microsoft’s compliance toolset for the cockroaches of Exchange is so limited....More

The woes of Exchange mailbox auditing 1

Mailbox auditing seems like a pretty good thing to have in an email product, if only to answer the eternal question of who deleted a particular message from the mailbox. Exchange 2010 was the first version of the product to include mailbox auditing. The sad news is that not much has changed since in either the cloud or on-premises product, which is both worrying and not particularly good when considered in the context of Microsoft’s overall compliance strategy....More

How small glitches can cause big problems for complex cloud infrastructures 4

Last month, I discussed whether a problem that caused Office 365 users to be unable to authenticate provided any indication that Azure Active Directory (AAD) was proving to be an Achilles Heel for Microsoft’s cloud services. That outage affected users in Western Europe on December 3 and underlined the dependency that Office 365 has on other parts of Microsoft's cloud infrastructure....More

Predicting the world of Exchange in 2016 7

Last week I looked back on what happened in the world of on-premises and cloud Exchange during 2015. This week it’s time to consider what might come along in 2016. Of course, I don’t work for Microsoft, so anything outlined here is total speculation, all done in the best possible taste....More

Active Directory and Exchange - too tight for a rename 3

1999 seems such a long time ago now, but that's when many of us first faced the need to deploy Active Directory (AD). For many companies, the need arose because Microsoft replaced the Exchange Directory Store (DS), used for Exchange 4.0 to 5.5, with Active Directory in Exchange 2000. The DS was very much like AD....More

Pretty Delve profiles need better synchronization

Microsoft uses “Delve profiles” within Office 365 as part of its strategy to make information easier to find, which of course is the mission of the Delve application. The theory is that you might not remember the name of an important document shared with you by someone, but you’ll probably remember the person. Therefore, if you navigate to the profile of that person, Delve will be able to reveal the documents that they have shared with you and the mystery is solved....More

Why mailbox anchoring matters 1

Tuesday’s EHLO post by Rob Whaley, a well-known Exchange guy who works on beta releases of the on-premises and cloud products, is all about how a remote PowerShell session connects to a mailbox on an Exchange server. Or, to use the term now popularized by the post, “mailbox anchoring”. I confess ignorance on the point as I was heretofore unaware of such a nautical reference in the context of Exchange....More

IE9 to deliver "diminished experience" for Office 365 users from January 12 3
