I think I might know the answer to this question, but without having a BB of my own to experiment on, I thought it might be best to ask actual BB users in order to appear knowledgable to my BB users here at the office.
I have a couple BB users here who currently have their mail forwarded from our Exchange Server to the provider's BB Webmail. Currently messages deleted off their BB devices are not deleted from their Outlook when they dock at the office.
The BlackBerries appear to offer Email Reconciliation, but does this require that the user use the Desktop Redirector software to forward & sync email, or can they use the Webmail service to forward their mail & do something crazy like synchronize with their outlook VIA the dock when they get back? The main reason for not using the redirector software is the lack of support for attachments, and I don't think these guys are too exciting about buying the RIM Enterprise BB Server for these folks. I guess what I'm asking here is, can I have my cake and eat it too?
