Hello All,

We are facing strange issue regarding calendar permissions in outlook 2010 SP2

We have granted four users "Reviewer" access to a particular users calendar.

All four users when try to book meeting or edit already booked meeting in shared calendar in outlook 2007, outlook 2013 and OWA they get error "You don't have permission to create an entry in this folder", which is correct when Reviewer permissions are in place, but when all these four users try to book meeting or edit already booked meeting in Outlook 2010 they get NO error and able to open/create/modify meetings in shared calendar which is strange behavior in outlook 2010.

Can anyone please let me know how we can prevent all these four users from opening/creating/modifying meetings in shared calendar in all client (Outlook 2007,2010,2013 & OWA), what permissions, settings, registry tweak I've to apply in outlook 2010 so that users will not able to open or create meetings in shared calendar when granted "Reviewer" permission.

We have Exchange 2010 SP3 CU8 in our organization.

We tried LimitedDetails, AvailabilityOnly, non cached mode settings also but no joy.

Hi Sandesh,

I just tested this issue in Outlook 2010 and here is the result:

When double-clicking on a date (or right-clicking on a date and clicking New Meeting Request) in a shared calendar, it opens a new meeting request window. However, the sender is me and the recipient is the owner of the shared calendar. If I click Send button, it will create a meeting in my calendar and in the shared calendar, just like I sent a meeting request to the owner of the shared calendar.

However, if I change the recipient of the opened meeting request and click Send button, it won't create a meeting item in the shared calendar, neither in my calendar. The meeting request won't arrive to the recipient's mailbox.

Is this what you are encountering?

I'm not sure if this is the expected behavior in Outlook 2010 since I haven't found any documentation stating this. I'll submit a feedback regarding this issue via internal way and I'll keep you updated if I get any information. Since users who have Reviewer permission can only send a meeting request from his own account to the owner of the shared calendar and it won't make any confusion in the shared calendar, I'd recommend you ignore this behavior.

If I've misunderstood something, please feel free to let me know.
