One Exchange 2010 SP2. Clients use Outlook 2010. Windows XP and Windows 7.
Some clients are having an issue with the Free/Busy and with the Automatic Replies. Problem clients are not on the same database. Exchange has been in place for 2 years. Clients had previously used the Free/busy and automatic reply without issue.
Free/Busy error: No Information, No Free/Busy information could be retrieved, Your server location could not be determined.
Automatic Reply error: Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later.
Seems like it might be the autodiscover, but am not sure.
