OpenDataSource method or property issue, Office 2016
"an error occurred merging data. the opendatasource method or property is not available because this command is not available for reading."
One of our users is experiencing this message when attempting to send a confirmation email from our primary software platform. I have unchecked the setting in Word that apparently is the typical cause of this error, as well as uninstalling and reinstalling office.
What is really strange is that this only occurs for a single user, when you sign in with another user on the same workstation this issue doesn't occur.
Go to File > Options > General and see if there is a check in the box:
"Open e-mail attachments and other uneditable files in reading view"
If there is, remove it please.
