Increase Rules Quota Limit in Exchange 2010

Lots of users use Rules in Outlook to organize their emails or move it to specific folder. They will then setup a list of Rules and then either set it to run when the email arrives in the Inbox, or the user run it manually say once a month to move the emails to its specific folder. When you create too many Rules, Outlook will give you an error that you can’t create anymore rules. In this article I will show you how to Increase Rules Quota Limit in Exchange 2010.

Exchange 2010 and all previous versions had a default Rules Limit of 32kb so when you create a new mailbox the user will be allocated 32kb of space to create Rules. In previous versions of Exchange Server you are not allowed to change the mailbox rules limit, but Microsoft change this in Exchange 2010.

Computer Cause Interference on TV

Have you ever experience that your Computer Cause Interference on TV screen? This is something that happened to me personally and it took me a while to resolve. First let’s start with my setup.

I had a Media Player connected to my TV to watch movies and listen to music. I decided to replace the media player with a full computer because the media player’s firmware could not keep up with all the new video file formats. So I built myself a new computer with a dedicated Graphics Card with a HDMI out so that I could connect it directly to my TV. Everything worked fine, but as soon as I switch back to my Satellite TV channels, all channels shows interference from the computer. This only occur while the computer was switch on. As soon as I shut down the computer the interference disappeared. I started to search the internet and found lots of “solutions” but most of them made no difference.

Computer Cause Interference on TV: Things I tried


  1.  I moved the computer and the TV’s power plug so that they are not on the same multiplug so that they are in different wall plugs. (This made no difference)
  2. I wrapped the Coax Cable (from the Satellite TV Decoder) and HDMI cable (from the Computer) with tinfoil to make sure there is no signals between the two cables. (This made no difference)
  3. I moved the computer about 1.5 meter away from the TV to ensure that it’s not maybe the computer power supply that is causing the interference. (This made no difference)
  4. I moved all power cables away from the Coax Cable from the Satellite TV Decoder to prevent any power interference. (This made no difference)

Then I realised that if I leave the computer on and unplug the HDMI cable from the TV the interference is gone. This meant that the issue is not the computer nor the power cables. It’s something to do with the HDMI cable or the display itself.

I also realised that my TV makes a very soft humming sound when the HDMI cable is plugged in. Then I started to play around with the display settings on the computer. First thing I did was changing the Screen Refresh Rate on the graphics card’s display driver. That also made no difference.

Eventually I found the problem! I had the Display Resolution on 1920×1080. This was the default setting and also recommended setting as per the size of the TV monitor. I decrease the Display Resolution to 1360×768 and that solved the problem. I would suggest, if your computer cause interference on TV, start by decreasing the Display Resolution. I might save you a lot of time while troubleshooting the issue.
