Hi Brianna, thanks for replying.

1. Version: Rio 9.2.1 build 673

2. Some examples include:

-106054 SLRTC 90% Quality Assurance Architecture Title Sheet

-413101 SBLD 60% Specifications 2015-01-12

-413101 SBLD 100% Design Comments 2015-06-25

For reference, we have tried moving the '%' symbol around, but failure occurs on a very consistent basis regardless of placement.

3. Failure occurs when attempting to send either LF links or copies. We have not tried it yet with individual pages to my knowledge.

4. Failure occurs with single or multiple entries-We have tried as high as 10. In all failure cases 1 or more of the documents included have had a '%' symbol  Documents are various and mostly include PDFs, Excel workbooks and Word Docs.

5. Documents range in size from a few dozen KB to a few dozen MB.

Thanks for the additional information.

I tried again with your sample document names using the same version, and was still unable to reproduce, so it's at least not just the document names. It seems likely to be something specific to your setup, such as the version of Outlook you are using, or something about these documents other than the name.

If you remove the % from the name completely, does it succeed?

Either way, you may wish to open a support case with your VAR, since troubleshooting will likely involve a further questions to pin down your particular setup, and you may need to provide sample documents in a briefcase.

Thank you Brianna, we'll keep checking and bring it up with our VAR.
