Hi All, I've transfered almost 500 mailbox users using OWA. Almost all of them got below error message: Outlook Web Access is unable to complete your request. If the problem continues, contact technical support for your organization and tell them the following: The Microsoft Exchange Mailbox server is currently handling too many other requests and was unable to handle this request. Thanks in advance...

Are you using a front-end server or do you connect directly to your backend server if you enter your OWA URL Deli
