5 Common Outlook Errors and the Ways to Deal with Them

Email messaging has now become the most common mode of communication for professional and personal purposes. And MS Outlook is a popular email client which handles most of these emailing tasks efficiently. It helps users to maintain emails, contacts, calendars, tasks, journals and other important information. However, handling all these things regularly is not an easy task. While using Outlook, many users have to deal with different types of errors.

In this post, we will discuss some of the common Outlook errors along with their causes and solutions.
1. “Your MS Exchange Server is unavailable.”
There are many reasons for this error. The error can be resolved by verifying a few settings:

  • Test SMTP server connection using telnet as suggested by Microsoft.
  • Check if PST/OST files are set on “Read Only.” Make suitable changes if they are set on “read-only” status. This can be done by locating the files on your system.
  • Start Outlook in safe mode. It is required in cases where third-party software or any antivirus programs are blocking Outlook.

2. “Cannot open your default email folders. The information store could not be opened.”
This is one of the common errors in Outlook. To resolve this error:

    • Type Outlook.exe in the Start Menu.
    • Right-click and select Properties.

    • Under the Compatibility tab, uncheck the box, “Run this program in compatibility mode for.”

  • Click OK and restart Outlook.

3. “Office Outlook will not open personal folders, or personal folders do not show up in Outlook.”
Many Outlook errors are related to PST files. Personal Storage files contain emails, contacts, calendars, tasks, journals and other important information. So, any corruption in PST files can stop the Outlook email client. Microsoft has provided an inbuilt solution, Inbox Repair Tool, to scan and repair corrupt pst and ost files.

    • Open scanpsts.exe and browse the corrupt OST file.

    • Run the repair process.

Other than this in-built utility, many third-party tools are available for repairing Outlook data files.

4. “None of the authentication methods supported by this client are supported by this server.”

This error is related to the authentication in Outlook. You can change authentication settings to fix this error:

    • Launch Outlook, go to File > Account Settings and click Account Settings.
    • Select Change and click on More Settings.
    • Select the Outgoing Server tab and uncheck the box, “My outgoing server requires authentication”.

    5. “Cannot send this item.”

    The reason for this error message is the formatting of the email message. This error takes place when you enter an incorrect destination email address. Always verify the ‘To’ email address before clicking the Send button. Another possible reason for this error is some modifications in HTML based email messages.

    • Verify the “To” email address.
    • Change the format of the outbound message from HTML to plain text or rich text.
