Microsoft Outlook is one of the most common programs for email access and works well with Exchange Server for business communications. Nevertheless, a common problem bothering users is the disconnection of Outlook from the Exchange Server. This disconnectivity can cause interruptions in productivity, refusal to send/receive emails, and restricted data accessibility. This blog will discuss the causes of this problem and possible ways of solving it.

Reasons for Outlook disconnection from Exchange Server

  • Unstable or intermittent internet connection
  • Misconfigured Outlook account settings
  • Outdated or incompatible Outlook version
  • Overly restrictive firewall settings
  • Conflicting third-party security software

Methods to resolve the Outlook disconnected from the Exchange server

Here are some ways to solve the Outlook disconnected from Exchange Server problem

Method 1: Check the connectivity and status of the mailbox server

If you encounter a particular error, you should attempt the basic solutions before going to the complex ones.

  • First, check the system’s connectivity and the mail server’s status.
  • Ensure the system is connected to the internet and the mailbox server is active

For the mail server:

  • You can attempt to access the Exchange Server using OWA (Online Web Access).
  • If you are to log in successfully, the server will be on and functioning as it should.
  • If not, please contact the administrator

Method 2: Check work Offline status

Work Offline is also a feature available in Outlook, which allows one to temporarily log out of Outlook and work offline without being interrupted by new incoming messages. It is also handy when the network is unavailable or is of substandard quality. In case the Work Offline is turned on by mistake or intentionally, Outlook will indicate the disconnected from the Exchange Server message. To resolve this,

  • Click on the Send/Receive tab.
  • Look at the Work Offline feature.
  • If yes, put the pointer on it, right-click on it, and select disable.

    • Send/Receive tab

  • It can also be solved by flushing the DNS in order to allow Outlook to connect to the Exchange Server. For this, press the Windows logo + R on the keyboard, then type ipconfig /flushdns and press the ‘Enter’ button.

Method 3: Open Outlook in Safe Mode

The incorrect and incompatible add-ins can also lead to errors, make the Outlook data file inconsistent, and harm the OST file. To resolve the issue and ensure add-ins are not responsible for Outlook disconnection, the following steps need to be taken such as:

  1. Exit the Outlook program and then press the Windows button and the R simultaneously on the keyboard to bring up the Run box
  2. Type Outlook.exe/safe and press Enter.
    bring up the Run box
  3. Insert your login credentials and observe the connectivity status on the status bar. If it is connected to Exchange Server, turn off all the add-ins in Outlook and launch the application again.
  4. To know which is faulty, enable the add-ins one at a time and check Outlook’s status for disconnected status.
  5. Last of all, uninstall any problematic add-ins installed in Outlook and use the Outlook application without any problem.

Method 4:Fix the certificate issue

Outlook access needs proper certificates that offer the best application experience. Now and then, if you are logged in to your Outlook account and you are unable to connect with the Exchange server, then this might be due to damaged or expired certificates.
Pro Tip: For certificates, the best practice is to contact the administrator and use the seamless services.

Method 5: Create a new Outlook profile

Sometimes, for some reason, your Outlook profile is corrupted, and creating a new one is the correct course of action.

  1. First, shut down Outlook and then go to the Control Panel in the system.
  2. On the Control Panel window, select Mail by clicking on it.
