Hello,
We are running Exchange 2013 with Outlook 2013 clients.
We created a Shared Mailbox and gave a couple users Full Access and Send As permissions via the EAC.
What we are trying to accomplish is to be able to allow the user with Full Access to be able to delegate rights to other users for this shared mailbox. However, I'm not sure if our method is even supported as I can't find any MS article doing it this way.
Once the full access user is setup, they'll open their Outlook and via the Account Settings page add the Shared mailbox as a separate account next their own.
After that, they will open the Account Information page and change the account to the Shared mailbox and open the Delegate Access page.
However, here we have been seeing different results for different users. One user will be able to get the Delegates window to open and be able to add users to it, but once they try to click OK it will give them an error stating "The Delegates settings were not saved correctly. Cannot activate send-on-behalf-of list. You do not have sufficient permissions to perform this operation on this object."
We then setup another user exactly the same way and when they try to access the Delegate page, they get an error stating "The Delegates page is not available. Cannot access Outlook folder."
Both of these users have been normal users with no Admin rights. I added myself (Domain Admin rights) to the Shared mailbox and was able to successfully add delegates to the mailbox without any problems.
Any suggestions?
Thanks
