QuickBooks struggles to verify the financial institution information with this download

Why would QuickBooks give such an email? Possible reasons are below:

if your QuickBooks copy is three years old (as an example, for current 2019, QuickBooks 2016 or earlier (or QuickBooks enterprise 16 or earlier), it won't import .QBO files. You must either update into the newer version or use Bank2IIF or CSV2IIF converters according to the file you have and import as IIF file instead of QBO.

Your bank or credit card company is no longer “allowed” by QuickBooks. Use Bank2QBO in order to make your QBO file from “allowed” standard bank.

Your .QBO file was not created correctly or “not ready” for your QuickBooks version. Banks and credit card companies create .QBO files differently. QBO files are extended OFX files (QBO can also be called QuickBooks OFX), but there some small but important differences when considering QBO and OFX files. QBO file may follow OFX specification, but is not acceptable for QuickBooks. In addition, different QuickBooks versions have slightly different requirements for “good” QBO files. Use Bank2QBO which will make your QBO file ready for your QuickBooks version.

Your .QBO file is from US bank, and you're wanting to import it on QuickBooks Canadian edition. Or your .QBO file is from a Canadian bank and you are clearly attempting to import into QuickBooks US edition. Use Bank2QBO in order to make your .QBO file importable into QuickBooks.

Your .QBO file is made from CSV or Excel file by third-party software. Use CSV2QBO to recreate QBO (Web Connect) file importable by QuickBooks.
