How to Search and Export Conversations with OCS IM Archive ViewerThe OCS IM Archive Viewer is a tool designed to read, search, and export chat logs created by Microsoft Office Communications Server (OCS) and related instant messaging systems. This guide walks through installation pointers, how search works, step-by-step procedures to locate conversations, exporting options, tips for filtering and bulk operations, and troubleshooting common problems.
What you need before you start
- A working copy of OCS IM Archive Viewer compatible with your log files.
- Access to the archived log files (typically stored as .msg, .xml, .pst, or custom archive formats depending on your archiving setup).
- A Windows system with appropriate read permissions for the archive files and any required supporting libraries (for example, Outlook if the viewer relies on MAPI/PST access).
- Backup of the original archive files before performing export or bulk operations.
Installing and launching OCS IM Archive Viewer
- Obtain the installer or portable package for OCS IM Archive Viewer from a trusted source.
- Run the installer and follow prompts, or unzip the portable package to a chosen folder.
- If the viewer depends on Outlook or MAPI, ensure Outlook is installed and configured with a profile that can access PST files.
- Launch the viewer. On first run, point it to the folder or PST/Archive file that contains your OCS IM logs.
Understanding the archive structure
OCS IM archives often organize data by:
- User mailbox or PST file
- Date (year/month/day)
- Conversation threads or participants (one-to-one or group chats)
Knowing this helps form effective search queries and apply date or participant filters.
Searching conversations — basic techniques
- Use the search box to enter keywords or phrases present in the messages. The viewer typically supports simple substring matching.
- Filter by date range to limit results to a particular period (e.g., last month, custom start–end dates).
- Filter by participant or sender to focus on messages involving specific users.
- Combine keyword + date + participant filters to narrow results further.
Tips:
- Search for unique phrases or uncommon words to reduce false positives.
- If exact-match is supported, wrap phrases in quotes to search the exact sequence.
- Use wildcard or partial word matches if the viewer supports them (e.g., “meet*” to find meets, meeting).
Advanced search options
Many viewers offer additional controls:
- Search within message bodies only, or include subject/metadata.
- Case-sensitive vs. case-insensitive options.
- Boolean operators (AND, OR, NOT) to combine terms—useful for complex queries.
- Search by message type (e.g., text chat, file transfer notices, presence changes).
If your viewer supports indexing, ensure indexing is enabled so searches are faster and can handle large archives.
Viewing search results
- Results are usually shown as a list with date, participants, and a message snippet.
- Click a result to open the full conversation thread in a reading pane.
- Use the thread view to see the full context of messages, timestamps, and attachments (if supported).
Exporting conversations — options and formats
Common export formats:
- Plain text (.txt) — simple, widely compatible.
- Rich text or HTML (.rtf/.html) — preserves basic formatting and inline links.
- PDF — good for sharing and archiving with fixed layout.
- PST or other mailbox formats — for importing into Outlook or other mail clients.
- CSV — useful for data analysis (one row per message with columns for timestamp, sender, recipient, message body).
Typical export methods:
- Single-thread export — open a conversation and choose Export > select format > save.
- Bulk export — select multiple conversations or a date range and choose Export All.
- Command-line or scripted export — if the tool offers CLI, automate large exports (helpful for compliance/archive migrations).
Example: export to CSV so each row contains:
- Timestamp, Sender, Recipient(s), Message text, Conversation ID, Attachment names
Exporting with attachments
- Some viewers include attachments in exports as separate files plus references in the exported conversation (e.g., attachment filenames listed in CSV).
- For PDF/HTML exports, attachments may be embedded or linked.
- When exporting a large number of conversations with attachments, ensure you have enough disk space and consider zipping exported bundles.
Preserving metadata and chain of custody
For compliance or legal discovery:
- Prefer formats that preserve timestamps, sender/recipient metadata (CSV with metadata columns, PST, or EML).
- Keep a checksum or hash of exported files (e.g., SHA-256) to prove integrity.
- Document export actions: who exported, when, which filters were used.
- Work from copies of archives to avoid altering original evidence.
Bulk export workflow (recommended)
- Create a working copy of the archive files.
- Open the viewer and apply filters (date range, participants).
- Run a search to verify the filter returns expected results.
- Use the viewer’s bulk export function; choose a format that retains needed metadata.
- Verify a sample of exported files for completeness (messages, timestamps, attachments).
- Compute hashes and store an export manifest describing the operation.
Common issues and fixes
- No search results: verify you pointed the viewer at the correct archive and that indexing is complete. Try searching broader terms or removing date filters.
- Missing attachments: confirm the viewer has access to attachment storage and that attachments were archived. Check permissions.
- Corrupt PST/archive: use repair tools (scanpst.exe for PSTs) or restore from backup.
- Exports truncated or malformed: try a different export format or update the viewer to the latest version.
Performance tips
- Enable indexing if available.
- Work with copies of large PSTs or split archives into smaller files.
- Close other heavy applications (Outlook scanning large PSTs can slow things down).
- Export in batches rather than all at once for very large datasets.
Security and privacy considerations
- Store exported conversations in encrypted storage if they contain sensitive data.
- Limit access to exported files and keep logs of who accessed them.
- Delete exports securely when no longer needed.
Troubleshooting checklist
- Confirm file paths and permissions.
- Verify viewer version and update if necessary.
- Ensure supporting software (Outlook/MAPI) is installed if required.
- Test search with known messages to confirm functionality.
- If crashes occur, check for corrupted archives and try repairing them.
Summary
Searching and exporting with OCS IM Archive Viewer involves indexing or loading archives, using keyword/date/participant filters, reviewing results, and choosing appropriate export formats (CSV, PDF, PST, etc.) depending on needs. For compliance, preserve metadata and document the export process. When handling large archives, use indexing and batch exports to maintain performance.
