Hello,
I started using TD with a shared space on my WebDAV server. I sent an invitation to a colleague and he got it and can work with me on this shared space. I sent two additional invitations to other colleagues and they only get the email about the invitation - not the invitation in TD. Even searching for it does not work. Whats wrong? I tried this now a dozen times (revoking invitation and inviting again). The colleague even installed TD again (including new activation of his account...) - nothing helps.
