This situation means that the user’s mailbox search index (usually Lucene-based) is corrupted, outdated, or has encountered a disk write error.
- Issue: When searching emails within the mailbox, no results are returned or outdated results appear.
- Impact: Users cannot access important emails, which significantly reduces workflow and productivity. This issue often arises after mailbox migrations or server interruptions.
🛠 Solution: Rebuild the Index
The solution to this problem is to rebuild the affected user’s mailbox search index. Depending on the size of the mailbox, this process can take a long time, and during this period the user may experience slower access to their mailbox.
| Process | Command | Description |
| Rebuild Mailbox Index | zmprov reindexMailbox user@domain.com |
Completely deletes and rebuilds the specified user’s email search index. |
| Check Indexing | zmprov gmi user@domain.com |
Used to check the status and progress of indexing. |
Note: To run this command, you must switch to the Zimbra user (su - zimbra), and typically the mailboxd service must be running.
