Q: – Is it possible to mix ZCS Open Source Edition accounts with Network Edition accounts in one installation?
Unfortunately you can not mix them, but there are multiple versions of Network Edition available to meet varying needs.
Q: – How much storage does each Zimbra account come with?
If you are installing ZCS on premise then storage is only limited by how much physical storage space you wish to allocate to each account (eg it can be unlimited, 10GB, 2GB, etc) depending on hardware constraints. The Administration Console allows IT team to easily set up "Class of Service" for the accounts.
Q: – What happens when my Network Edition 60 day Trial license expires?
Your basic ZCS features will still be working, but the following occurs:
- You can no longer add new user accounts
- Zimbra Mobile and the Zimbra Outlook & iSync Connectors will be disabled
- Administrators will see an alert message when they log into the Admin console
Of course, if you're not ready to purchase Network Edition but like Zimbra, you can always revert the Trial to the Open Source Edition. You will lose all the Network Edition benefits, but your data will still be intact plus you will have the basic features.
Q: – What are the top issues affecting performance?
Make sure that your client machines satisfy the system requirements for systems specs, operating system, and browser. Make sure the server machines meet the system requirements for hardware and operating system; size your hardware with growth in mind! Review the system requirements Evaluation and testing: Intel/AMD 32-bit CPU 1.5 GHz, 1 GB RAM, 5 GB free disk space for software and logs, mail storage space Production: Intel/AMD CPU 32-bit 2.0+ GHz, 2+ GB RAM, 10 GB free disk space for software and logs, mail storage space. RAID-5 not recommended for installations with more than 100 accounts
Q: – We use Active Directory, what level of "access" into AD does Zimbra need to authenticate users?
In order for Zimbra to use external AD/LDAP for authentication and/or GAL, you need to create a user that can see all user objects in the AD schema. Configuration of external auth/GAL is by means of an easy wizard in the Admin UI.
Q: – Does Zimbra set a storage limit or quota on accounts?
Administrators can set any storage quota limit they feel is appropriate for an account (or multiple accounts via Class of Service) in a deployment, eg 54MB, 2.2GB, 4GB… Technically there is no physical storage limit imposed by the ZCS platform itself. But practically speaking, storage limits should be set based on the physical hard drive space available, number of users, limitations present in any sync 'end points', and overall growth projections.
Q: – What phones are supported by Zimbra Mobile?
All Windows Mobile 5 devices Symbian S60 and S80 devices like the Nokia E-Series, Palm devices like the Treo 700P sync natively with Zimbra. (Some require additional 3rd party plugins) Blackberry is supported through a third party partner.
