Outlook won't update unless you close it and open it again. All users in the company experience this issue inside or outside the organisation, but I'm tempted to say it happens more often in the same network as the server (more complaints from users). It also gets fixed when IIS is restarted. Emails flood in but stop again and they do load themselves but you need to wait HOURS!
OWA works fine though, and so does access from mobiles devices.
Full Back Story:
Ok so our server crashed (the C: hard drive failed, only where everything is installed but no actual data is kept). I reinstalled Windows SBS 2008 (ours comes pre-loaded with Exchange 2007). I set up everything as I did 2 years ago when we had other server issues (putting everything the same, from memory). I decided I should write everything down this time just in case, so I have a list of everything I did when installing (if this will be needed).
Everything worked perfectly, but then about a month later a different hard drive failed - this time it was the one that contained all the company data, user data, mailbox's. I restored the data but because of certain factors it was loaded on a new drive letter (R: instead of S:).
Everything works fine except everyone complains that they need to restart outlook to get it to load any new emails or to load any category changes, but OWA works and it loads ok on everyone's mobiles. I presumed it was an issue with IIS, and found that if I restart IIS (restart the web app within the IIS Manager) then all outlooks update. I've also noticed that when I expand the ExAdmin, Exchange, ExchWeb, and Public virtual directories in IIS then it shows an error 'Could not find a part of the path \\.\BackOfficeStorage'
I'm not sure if that error is normal behaviour, but I presume it isn't. I thought it might be something to do with changing the drive letter?
I'm sure the issue clearly lies with SBS 2008 / Exchange itself (not the clients). I've tried best practices analyser and checking error logs but there isn't anything showing up.
Please help me find the problem!!!
