First things to check would be your (read/write) permissions and the status of the resource you're trying to use. <br />
<br />
What version of the Outlook client is in use on the affected computer(s)? Are you able to replicate the error on anyone else's computer or mobile device?<br />

If I understand correctly from your post, your HE system is run internally, on Exchange 2013. That should make it relatively easy to troubleshoot.

Exchange 2013 On PREM. &nbsp;So I have Autoaccept on and no delegates. &nbsp;Ive checked settings and everything is in place. &nbsp;When I got to Outlook and sent &quot;Location&quot; and type in a room name and send this meeting at the sametime as an already accepted meeting from that room then my meeting shows on my calendar as &quot;has not been accepted yet&quot; &nbsp;But I do not get a conflict email or a confirmation. &nbsp;So If you try this straight from the resource Calendar it gets declined and if you put the room into the TO: field and it has a conflict it gets denied. &nbsp;Im recurring the alert emails when sending TO: but when I do &quot;location&quot; which alot of folks here do then it just goes to &quot;your meting has not been accepted&quot;

Exchange 2013 On PREM.  So I have Autoaccept on and no delegates.  Ive checked settings and everything is in place.  When I got to Outlook and sent "Location" and type in a room name and send this meeting at the sametime as an already accepted meeting from that room then my meeting shows on my calendar as "has not been accepted yet"  But I do not get a conflict email or a confirmation.  So If you try this straight from the resource Calendar it gets declined and if you put the room into the TO: field and it has a conflict it gets denied.  Im recurring the alert emails when sending TO: but when I do "location" which alot of folks here do then it just goes to "your meting has not been accepted"

Room resource Doesnt Accept or Decline a Meeting
