"Microsoft Excel cannot access the file 'https://...."

Issue
When trying to edit an Office file in FYI I am getting the following error (for example, for an Excel file):

"Microsoft Excel cannot access the file 'https://...."

I can preview the file or export the document and then open it.

Refer also to "Sorry we couldn't find 'https://...." when opening documents for Edit in Desktop and for OneDrive Syncing.

Cause
This could be caused by one of the following:

• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same as a currently open workbook.

Solution

• Check the file name and path.
• Check if the file is being used by another program.
• Check if you currently have the file open.

If these are OK, there may be some background applications that need to be restarted. Please ask your IT administrator to check.
