Exchange 2010 shared calendar email address missing

I am unable to send appointments to our Office Shared Calendar. When I select Invite Attendees and select Office Diary I am told

This e-mail message cannot be delivered to Office Diary because the e-mail address is no longer valid.

I was playing around with Exchange Management Console yesterday I think I may have deleted something.

We are using Office 2010 on client machines. Server 2008 R2 with Exchange 2010

What happens when you try to recreate it?

After recreating it, you can follow my article to update your GAL: Manually Update Global Address List (GAL) on Exchange 2010

How would I create this for a Calendar?

Sorry if this is basic stuff but my Exchange 2010 is limited

What email address is it trying to send it to? As per your comment "This e-mail message cannot be delivered to Office Diary because the e-mail address is no longer valid." If you recreate the address then it should be able to send.

As stated above after recreating it, you can follow my article to update your GAL: Manually Update Global Address List (GAL) on Exchange 2010

I understand that I need to recreate the email address but I can't figure out who to allocate the email address to. The Calendar isn't a user or group.

Is the Calendar a shared public folder?

Ok can you possibly remember what commands you were playing around with?

That’s the problem I can't. What I was trying to do was clean up the Global Address List as it had public folders listed in it.

It was either Exchange Management or Active Directory Users and Computers that I deleted a list of things, extremely stupid

We would need to determine what email address was used. Have a look in your sent items for previous bookings made and see if you can figure out what the address was. You can always use AD-Restore Plus to restore deleted items in AD or to determine what has been deleted.

Hope this helps!!!

I know what the email address is.  AD-Restore sounds like the business. Do you have a link on how to us this? I'll Google it now

I have just fixed the problem. Under Exchange Management >> Toolbox >> Public Folder Console.
I disabled Mail on Public Folder then Enabled Mail and that seem to bring the settings back.

Thanks for the help your links did point me in the right direction.
