Outlook Temp Folder File Proliferation

Topic

New Reply

I work within an organisation that rolls out an auto-signature to all its users. This forces all emails sent to be in html format, and adds in the company logo at the bottom of the email. It all looks rather nice until a couple of weeks down the line…

After a point when a user receives an email, or saves an email they are working on the logo images change to the ‘wee red cross’ signifying that the image is not available. On further investigation it appears that the outlook temporary internet folder is stuffed full of the logo and can hold no more. Each instance of the logo that makes it to the temp folder is listed with the file name and number appended (logo (0).jpg, logo (1).jpg…). When it gets to the 100th instance of the logo (ie logo (99).jpg) it seems that no more can be created, and we start to see the red cross appearing. We then have to clear out all the logos from the temp folder and all will work again until they get back to logo (99)jpg, and it all needs cleaned out again.

Is there a way that we can stop this from happening?? And why, when we have a standard build of machine (Outlook 2003 SP2), roll out the signatures in the same way, seem to happen to some people more often then others (short of them sending out and receiving more emails!)

Any help/comments appreciated!

I assume the logo image is hosted on an external web site. If some users automatically download images and others do not, and that second group does not bother manually downloading images for the company’s own logo — I wouldn’t — then that might explain why some have many more of the images in the cache.

Our logo is not stored on an external site, but I think embedded into the email when sent. Looking at the HTML coding that is created within an email the graphic is found with this code:

I’m not sure of how the cid:661164016@31032010-29B9 actually relates to the name and location of the graphic, but I do know that as emails are being sent/received that the OLKxx folder starts to fill up with files named logo.jpg (0), (1) … all the way to logo.jpg (99). Once it reaches logo.jpg (99) (I guess that the folder can only contain 100 instances of files with the same file name??) when you receive through an email with the logo you only see the red cross and if you compose an email – the logo is there to start off with, but as soon as it has been saved (either through autosave, or by saving to drafts) the logo disappears and is replaced by the red cross. My guess is that on saving the email moves from being held in memory to existing in the OLKxx folder…

Its just that for some people this folder builds up more quickly than with others, and ideally I would like the behaviour to stop completely as it is not the easiest thing in the world to help navigate people to their OLK folder.

Thanks for any help/ideas (short of stop using logos in our signatures..)!!
