Hello,

Does this issue occur on OWA?

Whether the issue only occur when checking the emails in Sent Items folder?

Thanks,

No the OWA is Working fine and the problem just in the sent Item but i discover when i unchecked the cached mood in Outlook the LDAP path disappear and returned to origin Username

and when i check the cached mood in Outlook the LDAP path appear again

Hello,

Since OWA is fine, it means the email items are good on the Exchange Mailbox. The issue occurs because Outlook client read the email properties by mistake. So we need to troubleshoot the issue from the client side.

I think it will be more effcient by re-posting the issue on our Outlook Itpro forum, including the progress we have made.

Merry Christmas,

Thanx for your help Man

when i recreate a new outlook profile on Outlook 2010 or 2007 the problem disappear

but the problem appear on random user on random time and date " its like a pandemic " one by one

i don't want to appear on CEO laptop ;D

I have the same issue now.

I have deleted and re created the Outlook 2013 profile, I have deleted and created a profile with a different name, this issue disappears when the profile is newly created but quickly comes back. I have this issue on 2 Office 2013 machines, this issue has not appeared on over 850 Windows 7 Office 2010 machine's, connecting to Exchange 2010. I never encountered this issue until I upgraded to Office 2013

Outlook 2013 connecting to Exchange 2010, printing, setting calendar appointments all show user name as LDAP address.

I turned off cached mode and end users name displayed correctly in all. Not ideal but will do for now.

I have same issue too,

server Exchange 2010 SP3 Roll-up 8-v2

client outlook 2013 sp1

printing mails display users x.500 address instead of Name

outlook online mode not ideal on notebooks, any solution?
