Outlook signature image load and sending slow

Hi all,

I'm having a network wide problem with Outlook and/or Exchange.  Each user has an e-mail signature setup that contains our company logo as a small GIF file (6KB).  When a user goes to compose a new message, the signature text loads, but an image placeholder appears for the logo.  After about 30-45 seconds, the logo appears.

If the user tries to send the message before the logo appears, the Outlook window say "Saving" and have a green status bar in the bottom left.  The green bar is about halfway full and continues to say saving until that 30-45 seconds is up, the logo loads, and then the message sends.

Any ideas for what is causing this delay?

Thanks!

How big is the logo?  You might want to consider making it smaller.  It is a large image compress the image as a JPEG or GIF.

Tiny...6KB

It's worked fine for almost a year and a half until maybe last week.

If everyone is using that same logo file, could you be creating a bottleneck on your network?

Try this: have ONE user copy that network logo to their own personal network space (but on the same network server, if possible) and adjust their email signature to use THAT copy instead of the common copy.  See if that speeds things up.

If it's still slow, move their personal copy of the logo to a location on a different network server and update their signature.

If that is still slow, move their copy of the logo to their local hard drive and update their signature.

My guess is that the network is plenty fine, but several people vying for the exact same file is creating the problem.

Thanks Brian,

I have copied the files to my local hard-drive, recreated my signature using the local files, and the same thing is occuring.  

Now that we see it is doing the same thing using files locally and on the network, the only thing in common is the Exchange server.  Upon clicking the "New" e-mail button, does any information get transferred to the Exchange server?  

I took the logo out of the signature all together, and things work as snappy as they always were.  The same if I change my e-mail type to rich text or basic text.

Ah just thought of something else too.

The image serves as a hyperlink to our webpage.  Our webpage has recently changed from being served from an external host to being hosted internally.  The domain name is not resolvable internally.  Maybe the image is trying to resolve the hostname, causing the delay, and after a time-out the e-mail sends?

Well...it was a stab in the dark, but no dice.  Making the link resolvable internally didn't work, nor did removing the link.

Got it.

The signature was created for everyone using a template file.  The .html template file referenced the image through our webpage and the image file was replaced by another.
