Hi,
I have created one sandbox solution which contains one web part for word document mailmerge using open xml 2.0, and its work fine on our local SharePoint server.
When I upload this solution to office 365 its not working and give below error message.
Web Part Error: Sandboxed code execution request failed. Correlation ID: 6181299c-e792-0076-0281-e9080164cf50.
So I think that open xml sdk 2.0 is not supported on office 365, or is there any problem?
thanks in advance
Vishal
