gimitel,
I haven't see that one before what version of software are you running on MiCollab?
We just had an issue show up for 9.1.3.12 where it wants to add the MiCollab as a shared Element.
I think this is a problem with the new version, but there have been some known issues with previous 9.x versions of MiCollab and the MCD.
Thanks,
TE
