We have EV Client plugin installed with Outlook for Mac 2016 on Mac OSX Yosemite 10.10.5.
Plugin installed succesfully. However when I scroll to an archive emails and click Restore, it returns a message of "The operation could not be completed at this time".
When I click View it logs out with a message "Login failure: Unknown user or bad password", then prompts for credentials. Once credentials are supplied and click View, it's the same over and over again.
When I click Reply, the error message is "No message is selected for the operation".
This was working before our Exchange Server and client was upgraded. Are there things I can do to test/debug this?
