Quicken One Step update

Have you done a supervalidate?

Check your firewall settings and your anti-virus settings.

If that doesn't help, try doing "Update Now" for each account individually. Perhaps that will tell you if some accounts are working and others not.

There should be a log from the supervalidate. Maybe that log has some pointers to the trouble spot.

Have you tried creating a new file using 1 of your accounts?

I had a similar problem a few years ago and Intuit support suggested that I create a new file. Sure enough, OSU worked fine. I copied the old transactions to the new file and everything has been working fine since then. He said that there was corruption in the file that could not be resolved using the usual methods and that I needed to start over again.

Quicken doesn't provide any simple way to do what you appear to be trying to do.

But the problem you seem to be describing is one which you will need to fix yourself. Dealing with "transfers" is something that Quicken can come close to doing ... only under certain conditions ... conditions which you may not have taken into account.

For example: if you are trying to transfer Account A from Quicken file 1, to account A in Quicken file 2 ... and Account A had transfers to Account B in Quicken file 1, but Quicken file 2 does not contain Account B, you will have problems.

If your "new" file doesn't contain any account for the transfers to go TO or to come FROM ... you need to create those accounts ... or substitute some meaningful category for the transfer categories.

In that case, use the QIF import option "Special handling for transfers". I think that's the best Quicken can do in your situation. [When Quicken uses that option, it expects multiple QIF files, one per account. I don't know if the option survives an exit from Quicken.]

QIF files have no way to specify account currency, so if a new account is created by QIF file import, it will be in the Home currency.

Correct. Once a Quicken account has been created, you can not change its currency.

For your project, I suggest creating the accounts manually before you attempt to import any transactions for them.
