Enterprise Vault IMAP - invalid input string.

One of my customer wanted to use a new feature of Enterprise Vault 11 - archive access by IMAP. However they faced with a problem as the Metadata Store Build task didn't work correctly - status of the subtask was stuck to Will Retry. In the Enterprise Vault Event Viewer we could find the following info:

Command Line: "C:\Program Files (x86)\Enterprise Vault\EVMDSBuildTask.exe" -URL:tcp://192.168.203.200:23987/1d44983d_4abb_4f05_8988_7b9b2513e2fb/KVS.EnterpriseVault.ProcessManager41728762 -CUSTOM:1F2324323DAAS3B82B71B6C846E91013b00EVSERVER|False|1B80BEAA014R422323WEF9C2E7542AD1013a00EVSERVER

In the dtrace log for EVMDSBuildTask:

We realized that there would be a problem probably with "," in archive name:

Enterprise Vault - IMAP Metadata Store Build

The workaround was a typical for Veritas products 🙂 There was necessary to change the regional number format settings on the Enterprise Vault Server to use a period for the decimal separator as follows:

  1. Navigate to Start --> Control Panel --> Clock, Language, and Region --> Change the date, time, or number format
  2. Select Additional Settings on the Formats tab.
  3. Change the Decimal symbol value to a period "."
  4. Save new settings.
