Error: The section VersionOverrides 1.0 of the manifest is not valid. A Child node of the node VersionOverrides named webapplicationinfo is not valid

Question

I have an outlook addin working as expected on all platforms except the following.

• Outlook 2016 (16.0.5257.1000) MSO (16.0.5366.1000) 64 bits
• Exchange server 15.1 build 1713.5

When I try to install the addin - I get the error below

Error: The section VersionOverrides 1.0 of the manifest is not valid. A Child node of the node VersionOverrides named webapplicationinfo is not valid.

My maniest does contain the webapplicationinfo node which is a part of VersionOverridesV1_0 as per this

What am I missing here ?

Answer 1

Sounds like the host application doesn't support the Identity API 1.3 requirement set required for SSO (see the WebApplicationInfo element).
