Is Exchange Online Threatened by Ransomware?

with 4 Comments by Tony Redmond

Some people worry that Exchange Online mailboxes could be compromised by ransomeware and people will be forced to pay BitCoin to decrypt their messages. It's certainly a possibility, but out-of-the-box solutions exist if you're unlucky enough to be infected. That is, if you've done the necessary up-front planning to prepare for the worst to happen.,

Microsoft Deprecating Exchange Online’s Search-Mailbox Cmdlet

by Tony Redmond

Microsoft has started to flag its intention to deprecate the Search-Mailbox cmdlet. It's probably the right time to remove this cmdlet from Exchange Online because Office 365 compliance searches can serve the same purpose. At least, compliance searches can do most of what Search-Mailbox does faster. Some functionality gaps need to be filled before we can bid adieu to Search-Mailbox, but its time is coming.

    The PowerShell Mess in the Microsoft Cloud

    with 1 Comment by Tony Redmond

    PowerShell is a great way of automating common administrative Office 365 operations. That is, if you know what module to use and how to use the cmdlets in that module. Unfortunately things are a bit of a mess with too many modules and inconsistent behavior in areas like error handling. With so many development groups working on Office 365, the PowerShell situation might be inevitable, but it needs cleaning up.

    MyAnalytics Focused on Outcomes not Raw Statistics

    by Tony Redmond

    The new version of MyAnalytics is available to Office 365 E3 and E5 users and takes a different approach to the interpretation of data gathered about user work activities inside different apps. Instead of telling you the raw counts of messages sent and read and other data, MyAnalytics gives insights to help people work smarter and achieve a better work-life balance.

    How Retention Impacts Office 365 Storage

    with 2 Comments by Tony Redmond

    Office 365 retention policies help organizations keep information for as long as needed. But retention consumes storage. This isn't a problem for Exchange Online, but it is for SharePoint Online, because files held in the Preservation Hold Library are charged against the tenant storage quota. This isn't a reason to not use retention policies, but you should be careful.

    Stick or Stay: Should I Upgrade to Exchange 2019?

    by Tony Redmond

    Exchange 2019 has been around for six months. It's a good time to consider if on-premises organizations should upgrade or stick with the version of Exchange they run today. Exchange 2019 is a solid release, even if Microsoft's engineering efforts are largely focused on the cloud these days. Of course, moving to Exchange Online is an option too, but perhaps not for the dedicated on-premises deployments.

    Bringing Intelligence to the Office 365 Substrate

    by Tony Redmond

    Artificial intelligence is of major interest to Microsoft right now, so it really shouldn't be a surprise that Jeffrey Snover, one of their technical chiefs, is now heading the charge to bring AI to the Office 365 substrate. Quite what this means for the internal operations of Office 365, applications and clients, and customers is to be seen, but some interesting times lie ahead in the evolution of Office 365.

    Why Exchange Transport Rules are a Good Way to Encrypt Email

    by Tony Redmond

    Exchange Online transport (mail flow) rules are a powerful way to ensure that email from Office 365 tenants to specific recipients are encrypted in a consistent manner. Using rules relieves the need for users to become involved and makes sure that email is protected in a way that recipients can read messages. It's a good way to use the protection features built into Office 365.
