问题
When I try to connect to a MS Access 2016 database, it connects perfectly without password, but when I try to connect to the same database after encrypting it with a password, I get this error:
Cannot open the database. It may not be a database that your application recognizes, or the file may be corrupt.
I don't know what I should do - my database isn't corrupted, and I have to make it with a password. Is there a way to do it, or am I wrong in something?
File extension is .accdb

Hope your connection string as follows,
"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=[Path];Jet OLEDB:Database Password=[Password];"
So, you used Microsoft.ACE.OLEDB.12.0 driver and must be installed on your machine, as it doesn't come with windows. you can find the driver on this link
And hope this post also help to you. and also this
