"Error in Write in File" error message output to Excel File

[mmish]

I have a workflow that is pulling large sets of data from several databases and doing some minor transformation.  The data is then output to several sheets in one excel workbook to a location on a shared drive.  I am using a Block Until Done tool prior to each output. 

Output 1 is set to Overwrite File (Remove) and Outputs 2 and 3 are set to Create Sheet.

The workflow had worked seamlessly until today where I am getting the below error message.

Anyone familiar with this error and how I can resolve?

Does the shared drive have enough storage?

Hi @mmish 

Since the workflow worked before, I would investigate if there were any changes made to your network, as @AkimasaKajitani suggested

-drive space

-permission changes

-routing changes

-etc.
