The Enterprise Vault installation is currently in maintenance mode and consequently unable to process your request. Maintenance mode was initiated because [System Administrator requested shutdown]. (ID: CORE_MAINTENANCE_MODE)

Cause

The issue can occur if there is corruption with the maintainance-mode file. One of the possible reason for the corruption could be Antivirus Scans, hence this location should be excluded from Antivirus scan.

Solution

1. Rename the maintainance-mode files at location C:\Program Files (x86)\Enterprise Vault\EVIndexing\maintenance-mode and C:\Program Files (x86)\Enterprise Vault\EVIndexing\bin\maintenance-mode to old.
2. Restart the EV admin service.

Note : If the issue occurs in a cluster the same solution will have to be applied on all cluster nodes.

3. If the above steps does not resolve the problem then the index engine should be reset (see Related articles).
