This problem can occur because the Chat service in Exchange Server 5.5 writes its log information to the following folder by default
X:\InetPub\Chat\Transcripts\channel_name
where
channel_name is the name of the channel for which transcription capabilities are enabled.
Different transcription paths are used where
X is one of the following:
- Blank. Transcription logs are created and stored in the rootdrive\channel_name folder, where rootdrive is the drive letter chosen as the root drive.
- " \ " (without the quotation marks). Transcription logs are not created and there is an approximately 2 second delay for client channel entry.
- "Path" (without the quotation marks). Transcription logs are created and stored in the windir\System32\channel_name folder, where windir is the folder in which Windows is installed.
