Hi,

I'm not sure what the backup it was, a backup of the registry?

Would you please provide more details about how you re-configured these accounts back to Outlook? Did you just add the account manually in Outlook?

Try to create a new Outlook profile, add the Exchange Account to try again, does the issue persist?

I recently had to restore my account settings for Outlook 2010 following a reinstallation of Office.  I had taken a backup of what I though was all the registry stuff I needed and when I reinstalled the settings I thought it worked.  I have 4 IMAP accounts and one exchange account.  The IMAPs all work fine but the exchange doesn't.  

I've tried repairing the account but get the error "The action cannot be completed.  The connection to microsoft exchange is unavailable.  Outlook must be online or connected to complete this action".

I think it is a registry thing as I don't have any trouble with the webmail service and can check the same account on my phone.

Any ideas?

Thanks for the reply, sorry for taking so long to come back!

To backup the settings I copied the profile from HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles

I just reimported it into the registry to restore the profile.

I wasn't bothered about the actual emails, they could just download again.

I did try creating a new profile but I still get the same error message...

I'm still stuck with this, any other suggestions?

Hi,

Based on the error message, please refer to this kb below:

https://support.microsoft.com/en-us/kb/2264398?wa=wsignin1.0

This issue occurs when the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders registry key does not contain all of the required data. Specifically, these problems occur if the AppData string value is missing from this registry key.

Please try the fix in the kb and check the result.

Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

Thanks for that.  I had actually come across that article but the solution requires a working computer which I don't have.  Is there a way to manually fix?
