We are setting up an environment for a client. So far we have had the issues that three users cannot use the app in Outlook. It times out during Authorization. It works when using webmail. For two of the users it worked fine for a week but then stopped. For one users it start working after changing computer.
I assume this is a local Outlook problem but what is the fix? We have tried with trusted sites, reset the ost file, remove and add the app. Nothing have worked
(It is frozen like this for 1 min and then gives error message Client Loader timed out)
