FIXED! There's an updated beta version of LetSys available (V4.3.0.5) from the beta page: https://holletsys.co.uk/beta.htm This latest version replaces the standard email interface with one that should work in most situations. We have tested this reasonably extensively and the tests show that you c...

Please also be aware that the Windows 10 Mail App also does not support the necessary interface (MAPI). So this is not an alternative to either using Outlook or the built-in email client. For example, this reference makes it clear that Windows MAIL is a basic Mail client, with no MAPI support. https...

Thunderbird does not support the Microsoft "Messaging Application Programming Interface" (MAPI). So you can't send the booking confirmation emails that you are used to.

He had tried running the fix referred to above, namely executing the script CheckMAPI.vbs but this did not work. He subsequently repo...

One of our users has reported that the problem was resolved by a fix installed by Microsoft on 15th June.

I haven't verified this myself yet, but it would now seem that you can go ahead and install this new release of Windows 10.

Really sorry about this. Why people are willing to waste their time causing trouble for others I shall never know. I've just changed the board settings so all new registrations need administrator approval. This should stop problems as I will only approve registered users of the Holiday Letting Syste...

Note: You only need to read this post if you are running LetSys on Windows 10. We have had a problem reported by a user who had upgraded to Windows 10 Creator's edition, which started rolling out to users at around the beginning of April. This results in dates being shown incorrectly in the bookings...
