Back in November, I wrote about my early experience with the Office 365 Clutter feature. I’ve been using it on and off– mostly off, due to a rare bug that surfaced because my mailbox is actually hosted on a portion of the Office 365 cloud that descends from the old Exchange Labs “friends and family” tenant. The bug kept Clutter from correctly moving clutter messages automatically; once it was fixed things returned to normal after I re-enabled the Clutter feature, and I’ve been happily using it since.
One of the big advantages of Office 365 is that the service team can develop and release new features much faster than they can for on-premises services. Sure enough, Microsoft today announced three new features for Clutter.
The biggest of these is the ability to create transport rules that flag messages, or senders, as exempt from Clutter processing. This is exactly the same thing as specifying safe senders for message hygiene filtering, although the implementation is a little different. You’ll create a transport rule that has the conditions and exceptions you want, but with an action that adds a header value of “ClutterBypassedByTransportRuleOverride: TRUE”, as described here. I have not personally had even a single false positive from Clutter since I’ve been testing it, and I haven’t seen any complaints about false positive problems from other users, MVPs, or customers. Having said that, Microsoft was smart to include a way to exempt certain messages from processing, as this will soothe some users and tenant administrators who are worried about the potential to have important messages be misdirected.
Second, the Clutter folder can now be managed by retention policies. This is an eminently logical thing to do, and it nicely highlights the flexibility of Exchange’s messaging records management system.
Rounding out the trio, you now have a very limited ability to customize the message that users see when they enable Clutter for their mailboxes: you can change the display name that the notification appears to be from, and you’ll soon be abe to change the logo. Frankly, this is weak sauce; there’s no way to customize the text of the notification, add custom URLs to it, or otherwise modify it in a useful way. Long-time Exchange administrators will recognize a familiar pattern exemplified by customizable delivery status notifications (DSNs), quota warning messages, and MailTips in previous versions of Exchange: first Microsoft delivered a useful feature with no customization capability, then they enabled limited customization, then (after prolonged complaining from customers) they broadened the range of things that could be customized. Let’s hope that pattern holds here.
There’s still one weak spot in the Clutter feature set: it still requires individual users to opt in (or out). While it’s true that users would likely be alarmed by the sudden forceful application or removal of the Clutter feature from their mailboxes, it’s also true that Office 365 as a whole needs to provide better controls for administrators to regulate which service features users have access to. I am hopeful that we’ll see better admin controls (and reporting) for this feature in the future.
While these improvements aren’t necessarily earth-shaking, they do add some welcome utility to what is already a valuable feature. Clutter is a great example of a feature that can make a measurable positive difference in users’ satisfaction with the service, and I look forward to more improvements in the feature.
