Access 2010 statement gives error message on Win 10 system

[NoSmoke]

I have an Access 2010 program that works fine under Win 7 but gives an error message when running under Win 10.

The problematic statement appears to be:

DoCmd.SendObject acSendNoObject, , , Me.EmailAddress2, , , Me.EmailSubject, Me.EmailContent, False

An message appears stating an error has occurred and the program must close.

The associated program was written under Win 7 and run under Win 10 with the Access 2010 run-time app. In both cases, the email program the statement references is Mozilla Thunderbird.

I don't even know where to start looking for a solution and would appreciate any suggestions as I am attempting to migrate to Win 10 now that MS has announced Win 7 will no longer be supported after Jan 2020.

Thank you in advance...

Presumably this depends on Thunderbird being the default mail application. Is that the case?

Yeah, it seems to be smart enough to look for the default app (I was surprised when it worked, at least in Win 7). Dunno though if it has to be Thunderbird - it would seem unlikely.
