I've gotten really close to deploying Zimbra for a client of mine that needs push email, contacts, and calendaring for their business.
The requirements were that they could cache all data to their Macintosh laptops offline, and still have up to the minute meeting notices and contact data sent to their phones.
One big hurdle that we've run into is the ability to share and edit one big company address book - about 5000 records.
While Zimbra makes it possible to share each others contact list, and sync this list to the computer (and even seems pretty smart about handling edits from each persons shared list), there is no way to send these shared contacts OTA to the phone.
I wanted to know if this is a limitation with mobile platforms in general? When the architecture was designed (Exchange, Zimbra, Kerio, Communigate, etc), was the assumption made that people would only need to push contacts to their phone that they owned - much like their own email?
Was this a business strategy decision or just an oversight in general? Seems to be an issue across these types of solutions, unless I'm completely missing something.
If contact lists can be shared and synced with a user's local Address Book, what would be the limitation to also allowing shared contacts to be pushed back and forth to a person's phone via Activesync?
I know that in a huge corporation it wouldn't make sense to share out a company wide address book with 30000 people (I understand you could do an LDAP lookup if you're connected) - but what about a division or a team of people that all need access to a subset of the same data on laptop and/or mobile device?
In this case, we're using WM6 devices (with iPhones planned for future use)... I may be able to do a hack workaround by disabling OTA contact syncing and using Missing Sync to communicate to the phone via Address Book (and then AB back to Zimbra)...
unless someone knows of a fix??! I'm sure this has been asked 1000 different ways on the forums, but I've not seen a way to do this, or see if it's even a planned feature addition.
