So, it works with Exchange 2013? Perhaps it is just Office 365 (or our implementation of it) that causes it to not work? Perhaps it works because you are running Exchange in mixed mode?
I don't have access to EMS on the Office 365 side but your command does appear to work in 2010. You say you didn't do step 2 - you mean Create a user in Active Directory but no mailbox for that user (username U). or When it prompts for credentials, put in username G and the password for G. I'm assuming you mean the latter. Thanks for your help.

Yes, I was able to follow your instructions and set this up. Not sure if it matters, but are an on-premise EX2013/EX2010 hybrid shop right now. But everything I did, I did it on the EX2013 side. Also, I didn't have to do step 2 as I logged into a VM as user U and setup the mail profile with Outlook 2010. Instead of prompting me for a username/password, it just used my logged in credentials because user U has full access to the resource mailbox R. If you wanted, you could also add user U directly to resource mailbox R directly with EMS to see if that works: Add-MailboxPermission "resource R" -User "user U" -AccessRights FullAccess On Fri, May 30, 2014 at 5:23 PM, Curt Finley <[email protected]<mailto:[email protected]>> wrote: I have a situation where I'd like to give some users who don't have a mailbox of their own write access to a resource calendar. I've been able to accomplish this in Exchange 2010 as follows: Create a mail enabled security group (called G). Create a user in Active Directory but no mailbox for that user (username U). Add user U to security group G. Create a resource mailbox (called R). Give group G full access permissions to resource mailbox R. Create an Outlook profile as follows 1) Open the profile creation wizard. When prompted to enter name, e-mail address, ... put in the info for R but don't enter a password. 2) When it prompts for credentials, put in username G and the password for G. Voilà! You can open the profile and create calendar entries. I've tried the same technique with Exchange 2013 but it doesn't work. (Actually my test is in Office 365 but Office 365 is Exchange 2013 isn't it?) I tried making U a mail enabled user but that still doesn't work. Is there something that can be done to give a user without a mailbox write access to a resource mailbox? I know it seems like it would be simpler just to give U a mailbox. I'll spare you the details but in this situation it creates complications I'd rather avoid. Thanks for your help. Curt
