Mac performance with Exchange Server 2010 SP1

Question

Hi All,
I have some issue with Mac OS X 10.7.2 performance with when setting up new email connection Microsoft Exchange Server.
1) Use Apple Mail to create a new EMAIL account for an Exchange Account using Auto discover.  Note how long it takes.  In my case, it takes almost two full minutes or more until it comes back and is fully set up (and starts synchronizing the server folders).
2) Now use Apple mail create a new EMAIL account MANUALLY -- just don't fill in the password... keep hitting Continue until it shows the POP setting.  Select EXCHANGE and then fill in the appropriate details (mail.mydmain.com, check SSL enabled, etc.).  Setting up an account this way takes only a few seconds.
3) Use Microsoft Outlook 2011 for mac to create new Email account for an Exchange using Auto discover. it takes few second to completed.
I can summarize that:
- Use Apple Mail to create a new EMAIL account for an Exchange Account using Auto discover: Slow
- Use Apple mail create a new EMAIL account MANUALLY: Normal
- Use Microsoft Outlook 2011 for mac to create new Email account for an Exchange using Auto discover: Normal
In any case, do you have any solution to fix this issue.

Hi,
I'd like to know how did you set "send on behalf",from outlook give delegation permission or from Exchange Server give "send as" right?
Please try to use get-adpermission to verify if the user has "send as" right.
Manage Send As Permissions for a Mailbox

Note: After you grant send as right, please try to restart Microsoft Information Store.
By the way, do you receive any NDR or error information when you send on behalf of others?
