Suppose I asked a for a solution to a problem I had in a particular environment. But before the answer arrived, I lost access to the original environment.
For example if some question was about a particular SW and OS version, this could happen after changing (employer and) workplace to one with different OS, or updating SW or completely abandoning it.
Now the answer seems correct and I'd like to accept it but I have no way of verifying it.
I have several unaccepted answers like this and I feel like it's unhealthy for my Accept Rate, and more importantly, I believe the author deserves their Accept Rep. Example on SU: Disabling "Sign In " tab on startup - first, the Chrome version is is outdated, and second, I lost access to Windows platform (...yeah, that lucky kid I am! .-D)
I thought of:
Simply accepting the answer without verification (provided it has much more votes than next one)
Trying to create similar environment and verifying it there, probably "updating" question
Which might be unfair since other answer might come out as "correct".
Just leaving the question as is; no accepting
Is any of the above generally advisable? Is there a rule of thumb?
