When an RTF message that contains embedded images is sent out externally, it is converted to HTLM, and OLE conversion occurs on the images. OLE conversion works correctly, but the process cannot delete the temporary files that were used for the conversion. When these temporary files accumulate and eventually reach a combined size larger than 128 megabytes (MB), the conversion process starts to fail. At this point, every sent message loses the embedded images. Instead, the images are converted into a period (.).
- Manually delete the temporary files in the "%ExchangeInstallPath%\V14\Working\OleConverter" folder.
- Manually grant the "Delete" permission on the "%ExchangeInstallPath%\V14\Working\OleConverter" folder for the Network Service account.
