    Common Outlook Problems and Solutions

    Note: The errors and solutions mentioned below apply to Outlook 2007. Though most of them should work with other versions of Outlook too, you should be aware that they might not.

    Problem 1 – Outlook Stuck on Loading Profile

    This is the most common of Microsoft Outlook problems. Over time, emails, notes, calendar entries, attachments etc. keep piling up in the Outlook PST, making it abnormally large in size. It eventually reaches to such an extent that working with Outlook becomes nearly impossible due to its utterly slow speed. It may cause ’Outlook stuck at loading profile’ issue.

    Solution – The first solution here is to reduce PST file size. For this, you need to remove any and everything that is causing the PST to bloat up. Find out the folder called “Larger Than 100 Kb” in Outlook 2007, it will contain all emails that are larger than 100 Kb. Delete all unwanted old emails (especially the ones with bulky attachments). If you really need an attachment, save it to the disk but clear it out of the PST. Also, delete all other unwanted emails and clear out the Trash.

    The second thing that could do wonders is Archiving. Archive your emails by year. This will save large amounts of data to your disk, relieving the PST of its burden.

    Problem 2 – Outlook not Working or Not Responding?

    It’s ironic how something that’s meant to help can itself become a cause of the trouble. Many Outlook add-ins claim to help around with Outlook’s working and make things easier for you. Sadly, quite a few add-ins have bugs and many are poorly written. And, using a corrupt add-in may cause Outlook to crash without warning, or it may result in Outlook has stopped working error. Installing too many add-ins can make Outlook slow too.

    Other reasons that may cause the email application to crash or halt its working are a corrupt Outlook profile, corruption in Outlook data file, etc.

    Outlook stopped working

    Solution – To find out if add-ins are causing a problem, start Outlook in safe mode and see if it performs better. If it doesn’t, the problem lies elsewhere. However, if it does, go to Outlook’s Trust Center and disable any suspected add-ins, then restart Outlook normally.

    If disabling the add-ins doesn’t help solve the issue, try re-creating your Outlook profile. If this doesn’t help, skip to the next problem and its solution.

    Problem 3 – Outlook PST is Corrupted

    You’ll know if the PST is corrupted if you start seeing errors pointing out the same on opening Outlook. A corrupt PST file can lead to inaccessibility of all data within your Outlook since it won’t allow it to open.

    Corrupt PST File

    Solution – Microsoft’s built-in repair utility, ScanPST.exe proves to be quite effective in this situation. You can find it in your Outlook installation folder and just run it. However, if the utility freezes or fails to fix PST file corruption, using Stellar Repair for Outlook software can help.

    Problem 4 – An Email on the Office PC Doesn’t Show up on your Laptop

    When Outlook is installed on more than one computer, you may find that the email settings on one don’t match the other. Downloading an email on both would also lead to an inconsistency.

    Solution – Follow any of these solutions to fix this problem:

    • Copy the PST file from one computer to the other manually. Whichever computer has all the emails, copy its PST to the other manually, and then restart Outlook.
    • Switch to IMAP protocol that synchronizes the mail on the server with the mail in Outlook.

    Problem 5 – You’re Sending out Spam emails

    You may get to know from your contacts that they’ve received unwanted emails from you while you may not be aware of sending them. This could prove to be quite embarrassing if the receiver is an important business associate and the sent out email is inappropriate.

    Spam Emails

    Solution – The cause of this problem could be either a malware-infected computer with access to your email address or your email account being hacked. Changing the password could solve the latter problem. However, if you’re unable to do so, you should contact support immediately and report the issue.

    If, however, your computer is virus-infected, scan your entire hard disk with a premium antivirus program, other than your regular one. Meanwhile, also inform your contacts that something like this has happened so that they can be aware of such an issue too.

    You can also refer to this Manual guide for outlook related issues

    To Sum it Up

    Though the above points should pretty much capture most of your Outlook problems such as; ‘Outlook stuck on loading profile’, ‘Outlook not working’, ‘Outlook PST is corrupted’, ‘Outlook PST is corrupted’ however if you’re still facing some issues, you could try other fixes such as rebuilding your Outlook profile, disabling your antivirus, adjusting your calendar permissions, etc.

    But, you can save the manual efforts and time spent in Outlook troubleshooting by using Stellar Repair for Outlook software. The software is purpose-built to repair large-sized, severely corrupt PST files. It can also fix common Outlook errors if need be.

    7. My Outlook is getting crashed every time whenever I try to open it. I thought the problem was due to recently installed Add-in and even after uninstalling it, the same problem persists. I’m not able to access my emails now.

      What could be the reason? I think PST has become corrupt due to continuous Outlook crash? Suggest something.

      1. Hi Mikaela Pitkänen,

        Yes you are right. Your Outlook PST file has been corrupt due to continuous crash of Outlook.

        To repair damaged PST file, you can opt for Microsoft suggested free inbuilt utility i.e. scanpst.exe or as its alternative Stellar Outlook PST Repair.

So, to avoid permanent deletion of emails or to repair severely damaged PST file opt for Stellar Repair for Outlooksoftware. It will resolve your problem.

        If you face any difficulty while using the Scanpst.exe or Stellar Outlook PST repair, feel free to ask.


    8. Hey, I am facing some issues in my outlook; whenever I try to send emails a popup message appear like this: Error 0X80040116? Could you please suggest me solution?

      1. Hi Wright,

        Large PST file: Users usually ignore the warnings given by Outlook to remove the unwanted emails. Not deleting unwanted email data will make user Outlook PST file heavy in size and large size PST file outcomes in corrupt PST file.

        Header of PST File Corrupt: Outlook PST header’s sometime corrupt very easily and outcome in PST file corrupt. May be same is happened with you.

        You can resolve this problem by following opting for any of these methods:

        • Create new Outlook PST file
        • Repair Your Outlook PST file

        Though creation of new PST file would be tough task and as well this is not a secure method. Along it will result in loss of current email data. To resolve your issue I would recommend repairing it using Stellar Repair for Outlooktool. Tool will surely resolve your problem.
