Resource mailboxes can be set to forward meeting requests to delegates for approval. It sounds like this option is enabled for this particular room mailbox.

•   Automatically accept or decline booking requests   A valid meeting request automatically reserves the room. If there's a scheduling conflict with an existing reservation, or if the booking request violates the scheduling limits of the room, for example, the meeting duration is too long, the meeting request is automatically denied.

•   Select delegates to accept or decline booking requests   The delegates are responsible for accepting or declining meeting requests that are sent to the room mailbox. If you assign more than one resource delegate, only one of them has to act on a specific meeting request.

To add a delegate, click Add. In the Select Delegates page, select a user, click Add, and then click OK to return to the Room Mailbox page.

To remove a delegate, select the user and then click Remove.

Is the user seeing invites in their calendar for things they accept on behalf of the room mailbox?

Alan,

Yes, as mentioned in my first post. She is the delegate and she is seeing the invites which she excepts on behalf of the room in her own calendar. It's also in the room calendar, looks like a copy.

Kind regards

Hi ArneCroughs,

Was this meeting request also sent to the delegate so that she can see this item on her personal calendar?

Thanks,

She's not a participant in the meeting. All she needs to do is approve the request. It seems when she does it enters her personal calendar and the room calendar. She would like to only see it in the room calendar because it's cluttering her own.

Hi ArneCroughs,

Did this issue happened in Outlook or Outlook Web App or both?

If this issue only occurred in Outlook, I would like to suggest you recreate the Outlook profile and add the delegate account as the only one in the new created profile to see whether this issue persists.

If there are any questions, please feel free to post.

Thanks,

Hi ArneCroughs,

How are things going?

If there are any questions, please feel free to post.

Thanks,

This has been checked with the client, and recreating the profile doesn't seem to work.

This issue has been solved
