There are a few reasons why this can happen (we're working on more specific error messages), so here are a few things to try when troubleshooting:
- Try changing the name of the file slightly (e.g. add a number to the end).
- Try opening a copy of the document and work from the copy.
- Try saving the file to another storage location.
- Try removing and re-adding the storage location.
If you are receiving a "saveback failed" error message please look here for guidance.
