Exchange 2010/ Outlook 2010 "One or more users cannot be added to the folder access list. Non-local users cannot be given rights on this server"

Environment
Exchange 2010
Outlook 2010

Issue:
Users has been migrated from Exchange 2003 to Exchange 2010 and now few users are reporting that they are unable to share Calendar with the other users. 

While Adding users from GAL it shows RED Mark on the user and 
they are receiving following error

 "One or more users cannot be added to the folder access list. Non-local users cannot be given rights on this server"

Resolution : 

Convert the Mailbox Type to Regular, 

Set-Mailbox Useralias -type Regular

You can check the status from the following command

Get-Mailbox UserAlias | FL *type*

Still not resolved, then opend ASIEDIT.msc, > Domain Configuration > User Properties and find Attribute 

MxchRecipientDisplayType : 1073741824

MxchRecipientTypeDetail  : 1

In my Case MxchRecipientDisplayType value was set to '0' and changing to 1073741824 resolves the issue.
