"Failed to verify user identity, please log out and back into FYI before trying again"

Issue

I am getting the error "Failed to verify user identity, please log out and back into FYI before trying again"

I can use FYI functions such as Comment and Tasks, but if I try and open or preview an email or document I get the error "Failed to verify user identity, please log out and back into FYI before trying again".

Causes

Incorrect date or regional setting on the user's desktop

If there is an incorrect date or regional setting on the user's desktop this causes an error due to the integration with Microsoft Office on the desktop to create, documents, which does a security check as to the user's authenticity.

Solution
Refer to Incorrect date/time or region settings is causing incorrect date format, errors when opening documents or cannot view clients/documents
