A few weeks ago I’ve turned on Cloud App security feature in my Office 365 Subscription. I was surprised today when i started getting the alerts that there were some attempts made to login as my on my account. In less than two hours there were m15 attempts and they were all outside US and from an unknown device. First I didn’t know where it came from but when I logged on the links provided and I re-called that I did setup some policies a weeks ago.

As you can see below there were three email sent to me whenever there was an attempt made to hack into my account

Email Alerts

And here is the policy matched and alert was triggered

 

The Next Step – Review the alert

The next action was to Review the alert and investigate it. I was brought on to this page

 

What did I configure? It was not enabled by default

As I said above I created a policy while ago and based upon that now I’m getting these alerts

As you can see, in GOVERNANCE I’ve options to select the action.

Pro Tip !

Enable Multi-factor authentication 

 

Hybrid free/busy lookups fail between Exchange Server 2016 CU8 and O365

Microsoft has identified a condition where Free/Busy lookups from On-Premises to O365 in a hybrid configuration may fail.

 

Symptoms

After you install Microsoft Exchange Server 2016 Cumulative Update 8 (CU8), free/busy queries from Microsoft Office 365 users to on-premises mailboxes in hybrid environments fail if the cloud mailboxes are not archive-enabled.

Cauase

This problem occurs because of a known issue that affects OAuth connectivity in Exchange Sever 2016 CU8.

Workaround

To work around this issue, create personal archive mailboxes for each cloud mailbox.

Status

This problem is scheduled to be fixed in Microsoft Exchange Server 2016 Cumulative Update 9 (CU9). For a supported fix for CU8, contact Microsoft Support.

Hi, I’m speaking again after the summer break. This time I’m speaking to NYC Enterprise Collaboration User Group. There is no fee to attend this event but you will need to register the event on meetup. Click the url below.

Businesses of all sizes are taking advantage of the convergence of cloud and mobile technology to enhance collaboration and productivity, accommodate different work styles, and reduce costs. Many companies now let employees work from anywhere, provide cloud-based productivity tools so those workers can communicate and collaborate more effectively, and encourage them to use their own devices for work.

In this presentation/discussion we will take a close look at the Team and how it can best fit for your day to day work.

It is time to upgrade – End of life Exchange 2007

Exchange 2007 End of Life Roadmap

Do you know that April 11 2017 is the date when Exchange 2007 will no longer be supported by Microsoft.

If you haven’t already begun your migration from Exchange 2007 to Exchange 2016 or Office 365 now’s the time to start your planning.

What does End of Life mean?

Exchange Server, like almost all Microsoft products, has a support lifecycle during which we provide new features, bug fixes, security fixes, and so on. This lifecycle typically lasts for 10 years from the date of the product’s initial release, and the end of this lifecycle is known as the product’s End of Life. When Exchange 2007 reaches its End of Life on April 11, 2017, Microsoft will no longer provide:

  • Technical support for problems that may occur;
  • Bug fixes for issues that are discovered and that may impact the stability and usability of the server;
  • Security fixes for vulnerabilities that are discovered and that may make the server vulnerable to security breaches;
  • Time zone updates.

Your installation of Exchange 2007 will continue to run after this date. However, because of the changes listed above, we strongly recommend that you migrate from Exchange 2007 as soon as possible.

Benefits of upgrading to Exchange 2016

Simpler and Better Server Architecture – Single Server Role
Better Collaboration
Saving files to OneDrive for Business
Uploading a file to OneDrive for Business.
Most Recently Used lists populated with both local and online files.
Office 365 hybrid
Messaging policy and compliance
In-place Archiving, retention, and eDiscovery
Improved performance and scalability
Auditing
Antimalware protection
Integration with SharePoint and Skype for Business

What are upgrade options?
#1-You can migrate to Office 365
#2- If you don’t want to migrate to cloud then you can upgrade to either Exchange 2010, Exchange 2013 or Exchange 2016.

I still have more questions, where do I get more details?

Data Residency option in #Office365

Data Residency ??

Yes it was new term of me as well when i came across msdn website but this really a need for a number customers who has business partners, business operations, their customers in different region and have to meet their local country data protection laws or in other terms who are concerned about data sovereignty. Data Residency Option is the solution for those type of customer.

What is Data Residency Option? 
Customers with data residency requirements can request to move their core customer data into the new region or regional data center. We recommend our customers to take no action, unless their organization needs core customer data to be stored at rest in their respective new datacenter region. By choosing to move their data, customers limit Microsoft’s possibilities to optimize the location of core customer data at rest in either their current or the new datacenter region. As a customer in any of those two regions, you will experience the same quality of service, performance and security controls as you did before.

Data-at-Rest is not available by default
Yes you may lose the option for your data to be secured at rest if you choose to move your data to a different data center. Which means by default all new data center does not offer data-at-rest- according to above statement.

For customers who need to have their core data moved to the new region:

  • Customers will need to request to have their data moved within a set enrollment window. Review the How to request your data move page for more details about the enrollment window for your region and the steps to enroll into the program.
  • Data moves can take up to 24 months after the request period to complete.
  • We introduce no unique capabilities, features or compliance certifications with the new datacenter region.
  • The complexity, precision and scale at which we need to perform data moves within a globally operated and automated environment prohibit us from sharing when a data move is expected to complete for your tenant or any other single tenant. Customers will receive one confirmation in Message Center per participating service when its data move has completed.
  • Data moves are a back-end service operation with minimal impact to end-users. Features that can be impacted are listed on the During and after your data move page. We adhere to the Microsoft Online Services Service Level Agreement (SLA) for availability so there is nothing that customers need to prepare for or to monitor during the move. Notification of any service maintenance is done if needed.

 

Notes From Microsoft iGnite 2016 #msignite

Running from Hall A to Hall C and then back to Hall A I needed up walking/running approximately 4 miles (6 km) per day, yeah it was good cardio J

I went there to learn more about on-premises Exchange Server 2016 and Hybrid configuration with Office 365 BUT was not quite impressed though you search the sessions you will find approx. 57 sessions on EXCHANGE but most of the are just Office 365 features and product marketing. It looks like iGnite email related (messaging) content were focused to a specific customer market or in other words they ignored the large enterprise customer running complex exchange environment.

I’d also mention that there were some sessions which I liked most and one of them was just specific to Office 365 but it is related to on-premises stuff (Below is the list of sessions I liked most or in other word 5/5 on the score card).

Challenge cloud encryption myths and learn about Office 365 BYOK plans
Yes, now you can bring your own keys.  Very information session from Jaclynn.

Migrate to Exchange Online via Exchange Hybrid
2nd session of the day for Hybrid.  Tons of information, must watch Tim and Mike did an awesome job.  And yes don’t forget to run the RCW on-premises.

Meet twin sons of different mothers (MVPs and Exchange engineers). It was a very interactive session carried out by Tony Redmond with folks from Product Team (Karim Battish and Jeff Mealiffe) and Exchange MVP (Andrew Higginbotham and Jeff Guillet). The room was full of on-premises Exchange Enthusiast.

The Ultimate Field Guide to Office 365 Groups. Microsoft gave a lot of information at Ignite about future developments for Office 365 Groups. This session provided a counterweight in that it focused on how groups are used in the field. This session was carried out by Tony Redmond and Bejamin Niaulin.

Unplug with the experts on Exchange Server and Exchange Online
Another interactive session. Discussion on on-premises, Modern-Auth, ADFS and Hybrid

 

So to conclude that overall it was a busy event, specially with running from one hall to another (wish they plan it better next year). Other than attending these breakout sessions I got most of questions answered by meeting the product team at the booth, I spent HOURS with them.
