ColumnStore Index the New Cool non-clustered index feature in SQL2012 with
significant boost in performance while been used. I tried to create it on my
newly restored Database but I received this Error

“Create failed for Index Either the object or one of its properties is not
supported on the target server version.
(Microsoft.SqlServer.Smo)”

oh…!!! this is not cool, well not so fast…!!! it’s related to your
compatibility level of your database so this could be fixed very easy.

1. Choose your Database then Click Properties

2. choose Options tab and change the compatability level to
SQL Server 2012 (110). then OK

now try again to create your index and … Yes I can.

Lync Server Enterprise Voice uses the Exchange UM infrastructure to provide call answering, call notification, voice access (including voice mail), and auto-attendant services.

all of the notifications and voicemails are stored on the main mailbox of the user; which can have an impact on the user quota

so in order to roughly understand the impact "size on disk" for the voicemail; we have the below calculation.

The narrowband used codec is consuming 16Kbps; so the size on disk will be (16Kbps X 60 Seconds)= 960Kb / 8 bits = 120KB per 1 minute voicemail

so for a standard maximum 3 minutes voicemail message  =  360KB

Also notifications can be turned off from the Exchange2010 OWA Phone>Voicemail settings under notifications menu.; You can disable save call logging on the mailbox from the client side or from client policy from the server;

 this control can be done via PowerShell command (Set-CsClientPolicy –Identity Global  –EnableCallLogAutoArchiving $false)
