Can't recieve yahoo messenger offlines
 

Does anyone have experience fixing an issue like this and what did you have to do to fit it?

Here is the issue: People send me offlines and I am not getting them when i login to my IM account. I have tested this and it is not a machine specific problem. I have tested this on 3 different machines and confirms that I don't get offlines. I have also confirmed that sending offlines to another IM account which I have is ok (I do get the offlines). Only seem to be an issue with one specific account. I've been researching this issue for last 3 days and just going in circles.

Any advice is welcome. Thank you!

could it be that the other people do not have their IM client configured properly to send offline messages?
