Crash Com Error When Emailing/Printing
Quick Answer
"Crash Com Error" usually hits when QuickBooks hands off to Outlook/print/PDF and a COM/MAPI hook blows up (bad Outlook profile, preview pane, or corrupted print profile). Do this: Set Outlook as default, disable Outlook Preview Pane, run Tool Hub → Program Problems → QuickBooks PDF & Print Repair, then run reboot.bat from the QuickBooks folder. If it persists, repair Office and reset QBWUSER.ini.
What is this issue?
QuickBooks relies on COM/MAPI (Outlook) and Windows' print/PDF pipeline. Damaged Outlook profiles, the Windows/Outlook previewer, or corrupted QB print mappings cause the COM call to crash the app.
Problem statement:
QuickBooks crashes when invoking email/print because COM/MAPI or print bindings are broken.

Common causes
- Outlook/Windows updates change MAPI handlers
- The Preview Pane holds COM objects open; QuickBooks' call collides
- Corrupt QBPrint.qbp or XPS/Spooler issues
- Old COM registrations fixed by reboot.bat
How to Prevent It
Best Practices
- Keep Outlook default and Preview Pane off during QB emailing sessions
- Patch Office and QuickBooks regularly
- Add AV exclusions for QB program/data paths
- Close QuickBooks and Outlook before major updates
FAQs
Will I lose data?
No—these steps touch profiles/print configs only.
Does 32-bit vs 64-bit Office matter?
QB historically behaves better with 32-bit Office. 64-bit can work, but test.
Why does it only affect one user?
Most issues are per-user (Outlook/QBWUSER.ini/print profile).
