When Outlook application is in configured with an active Exchange account, you can confirm its connectivity by going to the Account Settings and applying the ‘Test Account Settings’ option. It will check the incoming email server and send a test message to verify the account. When Outlook loses the connection with Exchange Server frequently, then it affects your email communication. Here, we will discuss some troubleshooting method for Outlook 2010.

Resolve the intermittent connection issues in Outlook 2010

Follow the upcoming steps –

  1. Run Outlook and go to the File tab, then click the Info button.
  2. Select the Account Settings option under the Account Settings drop-down.
  3. Select the Email account; click Change.
  4. Now, click More Settings; go to the Connection tab.
  5. Select the Exchange Proxy Settings.
  6. Here, make sure that ‘On fast networks, connect using HTTP first, then connect using TCP/IP’ option is in Enabled state. If not, then enable the option.
  7. Restart the Outlook application, and the issue should get solved now.

If you are using the modern versions of Outlook like 2013, 2016, or 2019, then you can go for troubleshooting the Outlook application.
When the Outlook is configured with Exchange Server, then it shows its status as ‘Connected to Microsoft Exchange.’

Here is the whole troubleshooting process:

  1. When there is no connection with Exchange server, and Outlook shows its status as ‘Working Offline.’ Here, go to the Send/Receive tab and disable the option ‘Work Offline.’
  2. Now try to login to the Outlook on the Web Account. If it shows the error that the Exchange Server is unavailable, then follow the steps:
    • In profile settings, go to Tools.
    • Go to Account Settings and double-click the Exchange email address of the account.
    • Check if the Server Address is mentioned correctly.
    • Click More Settings; then to the Connection tab.
    • Go to Exchange Proxy Settings and verify if the proxy address is correct.

Now run the Outlook in the Online mode by going to Send/Receive tab and reconnect with ‘Work Offline’ option. Go to Files tab, then Account Settings and double-click on the Exchange email address. If the ‘Use Cached Exchange Mode’ is checked, then uncheck it and restart the Outlook again. If the Outlook runs smoothly now and there is no connection issue, then it means that your cache file (OST) is corrupt. You should delete the data file and create a new one.

Another troubleshooting option is to run the Outlook in Safe Mode. Go to Search option and input ‘outlook.exe /safe’. If the Outlook works fine, then you should delete the add-ins from the application.

Another method is to trace route your proxy server. Input the command tracert hostname in the Command Prompt, and it will enlist the connections with Exchange. If there is a problem in the network connection, then such services will load slowly. In such a case, you should contact your Internet Service Provider.

By using all these troubleshooting methods, you can confirm the root of error and rectify it also. But, if the problem is due to the corruption in Exchange data, then you will have to scan the database file using the ESEUTIL tool and remove the corruption. But, you should also know that the ESEUTIL tool may further delete the data if you perform the hard recovery. That’s why you should go for a secure option which not only removes the corruption but also saves the data.

Kernel for Exchange Server recovery software is the most suitable option in any corruption-related issue in Exchange database file. It can easily fix Exchange 2010 database dismounted error. Further, you can save the recovered data in multiple destinations like Outlook PST, Exchange Server, Office 365, or a Public Folder. It protects the data integrity and collects the data in a consistent format so that you can access the files as they were saved earlier.
