As part of my role at work – we continuously swap the company’s mobile phone – a Nokia windows phone so being able to reset Nokia windows phone to factory settings is quite useful as we store our contacts on the SIM card so restoring the phone back to factory settings before handing them on is a useful occurrence.

Warning: This erases all personal content on your phone and restores the factory settings._

The Lync Server Control panel is used to control most Lync user policies and settings so when the Lync Server control is blank – it causes an issue with maintaining and configuring the Lync server.

1. The Lync Server control panel relies on the Silverlight dependency in order to display properly – if your Lync Server Control Panel is blank – install Silverlight and restart the control panel.

On the Performance tab you can configure the following settings:

Compression level

You can choose the compression level for a backup:

• None – the data will be copied without any compression, which may significantly increase the backup file size.
• Normal – the recommended data compression level (set by default).
• High – higher backup file compression level, takes more time to create a backup.
• Maximum – maximum backup compression, but takes a long time to create a backup.

The optimal data compression level depends on the type of files stored in the backup. For example, even maximum compression will not significantly reduce the backup size, if the backup contains essentially compressed files, like .jpg, .pdf or .mp3
