Hi,
Our company has our own XML manifest button. [custom add-in].
We have support for shared folders tag to allow shared mailboxes to use this button too.
But for some reason, specific customers are having issues using this button via outlook client [WORKS ON OWA]
the error message they are getting: "API not supported for shared folders"
Additional details :
The tag <SupportsSharedFolders>true</SupportsSharedFolders> is in place in the XML.
The client version is built 2210/2209 which supports the requirement set of 1.8 [which introduced shared folders support]
Everything works perfectly on outlook web application the error occurs only via outlook client
Any suggestion why this could happen?
Here is how our XML manifest looks like:
