Office 365 Usage Location and Skype for Business Online

Questions often arise in Skype for Business Online (SfBO) administration regarding the a user’s registered “location”. In the SfBO admin center we see it as the location field in the user listing as shown here:

This subtle setting is important for the voice Phone System calling plan (PSTN) service configuration in SfBO because it restricts what phone numbers can be assigned to a user, and their associated emergency location. Specifically, only registered emergency locations (addresses) that belong to the same country as a users’ location can specified for that user. In addition, when assigning phone numbers to a user, only acquired numbers in the same country are available for . . . → Read More: Office 365 Usage Location and Skype for Business Online

Skype for Business Online PowerShell Throttling Limits

As many ITPro’s have found out through remote PowerShell scripting against Exchange Online, there are limits. 

The same holds true for Skype for Business Online when using the Skype for Business Online Windows PowerShell Module. These are often an issue when scripting across thousands of objects.  For example, applying a SfBO policy to 15,000 user objects.

The throttling limits are very similar to that in Exchange Online. From experience, here are the hard limits:

3 concurrent sessions per credential used to connect 10 concurrent sessions per tenant Throttle Limits for Resources and Types of Resources A resource is an object, or a type of object such as a Policy, . . . → Read More: Skype for Business Online PowerShell Throttling Limits

Key Skype for Business Online Policy Settings

As I work more with enterprises adopting Skype for Business (SfB) Online in Office 365, many questions arise about setting user policies which govern which features which compliance, security, and resource usage.

There are many policies (about 12 that applicable to individual SfB Online users), and each type of policy can have many settings (52 for the Conferencing Policy for example), and it is difficult to know what settings are available, what the individual setting enables/disables, and which ones matter the most.

In my experience the 4 most commonly used SfB Online policies are:

Conferencing External Access Client Voice

The importance of each policy type will depend on what features . . . → Read More: Key Skype for Business Online Policy Settings

Anatomy of a SIP Domain Change


Mergers, acquisitions, and branding initiatives usually necessitate a significant but poorly understood change to a Lync Server deployment: a change to the domain name used in the Lync user SIP address (the right-hand-side of the @ sign).

Making this change in a way that minimizes user disruption is a challenge. This blog post aims to provide additional insight and guidance on the user impact, the process to follow, and what changes are required to your infrastructure.

It was written for Lync Server 2010, but all of it should be applicable to Lync Server 2013 (as far as I know).

5 Tips for Installing the Lync 2013 Monitoring Reports

The Microsoft documentation for Lync Server 2013 has improved considerably from previous releases. Having recently walked through a couple of installations of the native Lync Monitoring reports, the process is documented much better than in the Office Communication Server days! The documentation related to installing the prerequisite SQL Server Reporting Services (SSRS) for example is much improved.

A Fix for the Lync 2010 Control Panel Crash Issue on VMWare

For those living with the annoying issue of the Lync Server 2010 Control Panel crashing on a VMWare image, a fix has quietly been released in the form of a new update to Silverlight (which was the underlying cause).

The original issue was caused by a Silverlight 5.x update (specifically Silverlight 5.1.10411.0) and the only workaround was to rollback to Silverlight 4.x. This was annoying when updates applied to the image re-upgraded Silverlight to the 5.1 version and the issue surfaced again.

On March 12, 2013 Microsoft released an update to Silverlight 5: see MS13-022: Vulnerability in Silverlight could allow remote code execution.

This updates Silverlight to be 5.1.20125.0 and . . . → Read More: A Fix for the Lync 2010 Control Panel Crash Issue on VMWare
