'Can't connect to Exchange' error in Dynamics 365 App for Outlook for some users

(2) ShareShare

Posted on by Community Member

Hello,

We have a problem with Dynamics 365 App for Outlook (lightweight app) for some users.
They get the message "Can't connect to Exchange". We have Exchange 2013 on premise, CRM is also on permise.
The weird thing is, it is not for all users. And the problem does not occur in OWA.

Any idea's what can be the cause of this?

Thanks in advance!

    We also have the same issue. Everything works fine in OWA but this is issue on the outlook client. Also we only get this app working when we run this app "as Administrator". Do anyone have idea off this?

    I think your problem, has to do with GPO's... Did you put your sites in intranet zone? Protected mode also has to be active for internet + intranet zone.

    Have you got any solutions to his problem yet? I have exactly same issue. Works fine with OWA, but not the client. I have set the GPO's settings.

    you are saying you dont have problems with all users. Does this problem belong to rights given to different users or roles? Are you able to login with administrator?

    If you run outlook as administrator, you don't get any user gpo's (not sure about computer gpo's). So if yours works when you run it at admin, it will be gpo's...
