Last week one of our 4 Exchange 2003 servers experienced 100% on its C:\Drive which as you can guess numerous issues with end users in MSOutlook.
That has been resolved by clearing space on the target server but since then we have received calls (40 ish) users out of 1,300 so only a small amount who are reporting that when they launch Outlook 2010 at the beginning of a session they receive the following message.
"The Server is Unavailable" 'Retry' > 'Work Offline' > 'Cancel'
When they click 'Retry' they connect OK to the Exchange environment. However, I need to avoid them having to do this all the time.
I have only done the following:
Run the /resetnavpane switch on a couple of PC's (still waiting for feedback before looking at Profiles, Cache Mode etc
(Note - would the 100% on the Exchange C:\drive last week caused any of the above to connected users at that time?)
