Time delayed appearance in shared contact folder

[Johannes Graumann]

Hello,

I made a puzzling observation with a shared imap folder (contacts): I access
this folder with the same client (kontact) from two different locations,
but when making entries to it, they are only visible from the other site
after a day or so. Excuse my newbieishness, but what might this be and how
to remedy it?

Thanks for any input,

Joh
