Thought I'd share my experience of sharing a mailbox.
I wanted a shared mailbox where users would not be able to delete any inbound or sent items.
su zimbra
#Grant permissions to entire account, sadly this cannot be done from the GUI (notice that I've NOT given Delete permission)
zmmailbox -z -m
sharedaccount@mydomain.com mfg / account
chris@mydomain.com rwixa
#Give full permission to chris on the drafts folder to prevent drafts getting stuck
zmmailbox -z -m
sharedaccount@mydomain.com mfg /Drafts account
chris@mydomain.com rwixda
#Mount the account inside the chris folder heirarchy
zmmailbox -z -m
chris@mydomain.com createMountpoint /sharedaccountbox
sharedaccount@mydomain.com /
You must upload any signature logos to the briefcase of the Shared Account.
(I think that "may" be a bug)
The calendar and tasks also show up for chris, I may yet grant delete permissions to them ... maybe !
So far so good, except the shared folders do not show up in Mobile Devices, which is a pain, and the Zimbra Mobile HTML client does not appear to handle identities in the same way as the normal HTML Client.
Thanks again for a great product.
