O365 64 Bit Outlook Error regarding Outlook "Be set as default mail client" when Dragging Email into LF

asked on May 22


Customer states that starting today, they are getting the following message:

"Either there is no default mail client or the current mail client cannot fulfill the message request. Please run Microsoft Outlook and set it as the default mail client"

They stated this worked up until today.

They are on 64-Bit O365 Outlook. In looking at the release notes for 10.3.1, 10.4.1 and 10.4.2, I see 32/64bit Outlook is compatible with the office integration:

Laserfiche Office Integration Requirements:

Microsoft Office: Microsoft Office 2010 (32-bit and 64-bit), Microsoft Office 2013 (32-bit and 64-bit), Microsoft Office 2016 (32-bit and 64-bit), Microsoft Office 2019 (32-bit and 64-bit)

Now O365 is not listed, but I know Outlook 2016, 2019, and O365 use the same code base:

Office 2016 and Office 2019 now use the same code-base as Office 365 and your license determines which features are enabled.

If this is the case and it did work for the user before today, could there be an issue with the lfoffice-64 bit integration install?

Appreciate any feedback,

Jeff Curtis

This happens when a different email application is set as the default. The user could have done this without knowing it. Try following these steps.  If that doesn't work, please open a support case.
