We have an application sending mail through Outlook automation.
We got a support call where the message mentioned in the title came up.

When looking at the properties of the recipient(s) in the message, it turns
out that the recipients email address also shows up as the e-mailtype.
The code looks OK (as far as I know, you can't set the e-mailtype through
Outlook automation).

This is the first time we experienced this. The app works for a year or two
now at various locations, with or without the use of exchange server.

TIA, Hans
