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
