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. In the field we have seen office workers with Zimbra accounts as large as 6 to 7GB! (Don’t ask us how someone gets that much email).
