Things that you should keep in mind when working Office Web Apps Server 2013 and Lync Server 2013


Since Office Web Apps Server 2013 is becoming more and more an important role that organizations is relying upon for Lync server 2013 and other products, I have decide to share this piece of information with you that might help you save time when troubleshooting existing environment, and deploying Office Web Apps for Lync server 2013 .

What is Office Web Apps Server ?

Office Web Apps Server is a new Office server product that delivers browser-based versions of Word, PowerPoint, Excel, and OneNote. A single Office Web Apps Server farm can support users who access Office files through SharePoint 2013, Lync Server 2013, Exchange Server 2013, shared folders, and websites.

is it required for Lync Server 2013 ?

Lync Server 2013 doesn’t requires Office Web Apps Server to be deployed in order to function, however it is required whenever you have the necessity or the requirement to enable Lync users to upload and share PowerPoint presentations during conferences. it is good to note that using PowerPoint presentation sharing will dramatically decrease bandwidth requirements during presentations hence enhancing the overall Lync meeting experience.  Read more ›

Bulk approving existing ActiveSync devices after enabling ActiveSync quarantine

One of the biggest problems of enabling ActiveSync Quarantine in an established organization is that, once enabled, it will block all existing devices.

I needed a simple and effective way to allow ActiveSync for the existing 2500+ devices and I was surprised that I couldn’t find a script that is actually working so I am sharing mine hoping it can help someone else.

Before I tackle the script this is the cmdlet needed to enable ActiveSync quarantine in your organization

Set-ActiveSyncOrganizationSettings -DefaultAccessLevel Quarantine -AdminMailRecipients -UserMailInsert "Your mobile device type has not yet been approved for use. Please contact the Help Desk for further assistance."

Keep in mind that this will directly quarantine all ActiveSync devices and users are likely to receive numerous emails in their inbox stating that their devices needs approval, so be ready for some phone calls.

Next step was to allow all existing devices, the script and its explanation can be found below

Lync Server 2013 added support for SQL Failover Clustering

Seems like Microsoft recently updated the Database Software support for Lync Server 2013 to include Failover clustering as a supported Database high availability solution in addition to SQL

We can directly notice that SQL failover Clustering support has been introduced without the need to apply any Server side updates. which confirm that this recent statement is the result of the extensive tests applied by  Microsoft and the clients that participated in the testing program.

it is good to note that active passive failover clustering is only supported, so I believe that doesn’t  include SQL always on availability groups.

For my opinion this is another important update introduced to Lync sever 2013 product which will be most welcomed by database administrators, which doesn’t encourage using SQL mirroring and also in organizations where SQL consolidations are a required.

Reset Search Index in Microsoft Exchange 2013

If you happen to need to reset the search index for an Microsoft Exchange 2013 mailbox database you would have noticed that the “ResetSearchIndex.ps1” script that used to be present in Exchange 2010 was removed. So this is what you should do to reset the search catalog of an Exchange 2013 mailbox database

  1. Stop-Service HostControllerService (you can simply run this command from powershell or stop the service in the services mmc
  2. go do the folder hosting your mdb file and delete the folder named with a long GUID
  3. Start-Service HostControllerService

That’s about it
