I already read my owner's manual, and it did not address this problem.
However, I did find a fix on brickboard.com and matthewsvolvosite.com.
For the benefit of the next person who encounters this problem:
- remove the trunk paneling covering the gas tank area
- look for a long, silver wire with a loop on the end (manual door release)
- gently pull the loop towards the rear bumper of the car
- spray fuel door locking mechanism with WD40

Bad Volvo! Bad! Why, once they had something right, would they change it
to make it less good?
You say that the owner's manual for the '97 850 doesn't mention anything
about the locked fuel filler door.
But in the manual for the '95 850 it does!
In chapter 5, 'In case of emergency...', there is a section for
'Troubleshooting' and on page 5-17 there is a paragraph titled (can you
imagine?) FUEL FILLER FLAP DOES NOT OPEN [upper-case in the original].
There one finds, with clear illustrations even, the procedure one needs
to follow in order to deal with this problem.
So...for future googlers who find this thread: if you've got a '95, the
info is in the book but if you've got a '97...
cheers,
Henry

And if that does not work, just unplug the electrical conector from the
solenoid and problem is solved. You just won't have a locking door anymore.
I did this on my '95 after multiple sprayings with WD-40 that did not solve
the problem permanantly.

The 1997 850 Owners Manual [which is at
http://new.volvocars.com/ownersdocs/1997/1997_850/97850_000.htm ]
states on Page 6:18:
"Fuel tank cover does not open
Faulty motor in fuel tank cover
(Sedans):
Open the cover panel on the right tail light unit and pull on the hook.
The fuel tank cover can then be opened.
(Wagons):
Remove the right floor cover (the center storage compartment must be
opened first) and the cover panel on the right lower tail light. Pull on
the hook and the fuel tank cover can then be opened."
If your manual doesn't have this then download a copy.
