Outlook Very Slow to Open old emails

I have a network with a Small Business Server 2003 (new server spending), Windows 7 Pro PCs 64bit with 8Gb RAM. Office 2010

Everything has been running fine but suddenly 2 PCs are struggling to open any emails that are not todays. The error is Outlook is trying to retrieve data form Exchange.........

I have tried switching on Cached Mode but it never finishes creating the .ost file and new emails are not delivered. It was left to run over night.

I have reindexed and disable Windows search. I have uninstalled the anti-virus and tried and its the same. Everything else on the PC like opening files, browsing the internet is fine.

The user has 7.5k email in their inbox but a different user who is having no problems has 35k.

There is plenty of space on the Server and the PC.

Outlook has the latest updates.

If todays emails are opening they are absolutley fine.

Any ideas?

Install this specific account to another pc and try to receive those mails

Post the results

I tried logging on the the PC (with the problem) with the user who doesnt have a problem on their PC and they have the same issue when their account is put on to the faulty PC.
Nice, so the problem is, as you said already, the PC

-Did you create a new windows profile (and new outlook profile) from scratch and tested the pc?
-Do you experience other problems to this PC except outlook?

Test in Outlook Safe Mode if the problem still occurs

1. Click Start | Run.
2. In the Open box, type: "Outlook /safe" (without the quotation marks)
Notes: There is a space character between Outlook and the forward slash (/).
3. Click OK.

The above will tell us if an Outlook add-in is causing the problem

I tried it on a different PC (which doesnt have a problem) and the problem persists. Not as badly but it is not as good as it should be.

sorry missed your other reply.

It now must be the outlook account. I have tried Outlook Safe and the problem is the same. I have deleted and recreated the account on the PC.

Also, if it is the actual Exchange account how easy is it too delete the mailbox in SBS 2003 and then create a new one and attach it to the existing user? Or do I have to export the mailbox, delete the user and recreate the user and import the .pst into the new account / mailbox?

I am going to try eseutil /p and then /d to see if it sorts the problem out. This is because not all users are affected and I can run these over the weekend. Hopefully it might sort the corruption out?

I will archived the old emails & attached them as a data file
Optima SystemsNetwork EngineerAuthor Commented:
the problem is that anything I try to do is very slow. I enabled Cache again to try and get a local copy and it took 2 hours to create a 43Mb file. The entire mailbox is 2.5Gb so it would have taken days.

If i try to run an export or archive it will take as long.

Is there a reason why the eseutil isnt worth a try?

Have you checked for connectivity problems with the exchange server?

That may be the problem more so than a problem with the mailbox and exchange. The suggestion to check from another PC that is not having an issue would be verification of that

Optima SystemsNetwork EngineerAuthor Commented:
In an early comment I mentioned I tried the account / profile on a PC where the user doews not have the problem and the problem persisted so it must be the account rather than connectivity problems.

What happens if you log in as the problem user to Outlook Web Access? Does the problem also exist in Outlook Web Access?
Optima SystemsNetwork EngineerAuthor Commented:
I solved this by uninstalling McAfee anti-virus and GroupShield off the server and everything has started to work perfectly. I will switch to Symantec Endpoint.
Optima SystemsNetwork EngineerAuthor Commented:
None of the suggestions worked and in the end by uninstalling McAfee from the Server it solved the issue.
