This problem has now affected other LetSys users. In the most recent case it was caused by a re-installation of Outlook 2010.
Once again, this was fixed by running the script
CHECKMAPI.vbs This script (it is documented) checks and correct the registry settings needed to get MAPI to run.
MAPI stands for "Messaging Application Programming Interface" and is used by LetSys to send emails via your own client.
I've run it myself just to check for any problems.
Please backup before running it!
CheckMAPI.vbs is provided by MYOB. Run it and then reboot.
This script can be downloaded from here:

Documentation is not good, but I found the following instructions, which I've edited together from different sources:
The MYOB website states "Note that this tool has been created independently and provided to MYOB so we take no responsibility for its use."
To run the tool:
- Click the following link (if prompted, choose to save the file to your Desktop):
http://get.acclivitysoftware.com/downlo ... ckMAPI.zip
- Depending on your web browser and its settings, clicking this link may automatically open the ZIP file as shown in the following step.
- If the ZIP file doesn’t automatically open, double-click the downloaded ZIP file to open it. You’ll see it contains a single file called CheckMAPI.VBS
- Double-click the CheckMAPI.VBS file to open the tool.
- Follow the on-screen prompts to run the tool and fix your issue.
If for any reason you need to undo the changes made by this tool, simply double-click the downloaded CheckMAPI.VBS file to run the tool again. You’ll then be able to restore your original Windows settings."

Please note this problem is caused by Microsoft altering your machines settings when you upgrade Microsoft software. The problem is not caused by the Holiday Letting System. This suggestion is made without any assurance that it will work, although, as above, it has worked for other users. Brendan Blake
