When sending an email to one recipient I get the following message from a recipient with a disconnected mailbox: Delivery has failed to these recipients or distribution lists: Becky Wicks The recipient's e-mail address was not found in the recipient's e-mail system.

Many thanks Kelly Kelly Newell

Hi Kelly, The disconnected mailbox might be still at forward email list of the mailbox. Regards from www.windowsadmin.info | www.blog.windowsadmin.info

Are you sure that one recipient doesnt have this user listed as a delegate in outlook?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

You can use ADSIedit tool to check delegate and forward setting on the problem user. If you have not removed the delegate setting, when you send the meeting request, it also will forward to the disconnected mailbox. Thanks, EvanEvan Liu TechNet Community Support

I Have checked both on the server and on the users pc and there are no delegates, any other ideas would be gratefully received. Kind Regards KellyKelly Newell

On the users outlook save all his outlook rules, close outlook and run outlook /cleanrules than test sending again.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Any updates on this? If you still have issue on that user, please use ldap to export the configuration on that user, then we can know more information about the problem user. Thanks, Evan Evan Liu TechNet Community Support

Hi Evan, I tried the above and it worked for a couple of test calendar invites but is now happening again, the user in question has been deleted so I am unsure as to how to get the configuration information you require? Regards KellyKelly Newell

What did you do exactly ran outlook /cleanrules on the existing user you're sending the invite to right?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Yes and it worked for a couple of days then the bounce messages came back again, she does have access on mobile and also on an additional laptop, so should I run on the laptop as well? would the rules be on the mobile as well? and therefore there is a sync issue? Advice would be greatly appreciated. Thanks again KellyKelly Newell

Hi Evan,I'm not sure what Idap is? please can you advise? Thanks KellyKelly Newell
