Error Occurred in Workflow ....

Sep 23, 2014 at 8:06 AM
Need help on below scenario,

• We have email enabled library and users can send mails with documents to that library.
• There is a workflow which triggers on new item with some actions to extract words from Email subject and then route drop off library. In content organizer rules we check those words , then route to the relevant destination. [Library -> Folder]
Workflow error occurred only with Excel files but not with other file types such as PDF, Word.

Any workaround for this ..... ??
Thanks,
Sanka
