Hello. My organisation has one forest containing two domains. The two domains correspond to two different geographical locations.
In the domain I manage, I have two Exchange 2013 CU7 Standard servers in a DAG. Both servers have both the CAS and Mailbox roles installed. The servers are running Server 2012 Standard. The two servers are on different subnets. One server, which is usually our active mailbox server, is at our primary data centre. The other server is at a standby data centre. The two sites are separated by a WAN link.
The other domain in the forest has one Exchange 2007 server, as well as two Exchange 2013 CU7 servers in a DAG.
In the domain that I manage, our users run Outlook 2010 Standard on Windows 7 Professional. I have one user who is presented with a “MailTips could not be retrieved” message in Outlook. The user does see MailTips through OWA. The same behaviour is observed when the user logs on through a different PC on the domain.
The user’s MailTip settings in Outlook are the same as those for users who are not experiencing the issue. The user also has the same LAN and proxy server settings, in Internet Explorer, as other users who are not experiencing the issue. The user can set her Out of Office message. The user does not have any different add-ins than users who are not experiencing the issue.
Removing and re-installing MS Office 2010 has not resolved the issue. If you have any insights into how to resolve this issue, please share them with me. Thanks.
