Marketo Sales Connect/Toutapp will no longer be supporting our legacy .Net Add-In for Outlook, as of May 19, 2019. Because Marketo made a replacement add-in available in February 2019, we expect minimal impact as there are teams that have already been progressively migrating on to the new add-in.

If you experience an issue when trying to use the .Net Add-In on or after May 19, 2019, you will be directed to update to the new 0365 Add-In.
