Microsoft Outlook 365 - Something is wrong with one of your data... RRS feed

  • Question

  • Dear people,

    recently in our company we've switched to the newest version of the Office. Office 365 to be exact. We use O365 Exchange server. From today i have been experiencing, that my outlook can't run, because a message is always showing up.

    It says: " Something is wrong with one of your data files and Outlook needs to close. Outlook might be able to fix your file. Click OK to run the Inbox Repair Tool." 


    I tried to go through the repair process, but after i do everything this message will constantly show up

    What i tried: 

    1.) Uninstall Office - Didn't work

    2.) Remove Outlook profile from control panel > email  - didn't work

    3.) Tried to force remove Office + All of the files/registry as well - didn't work

    4.) Tried to run it in safe mode ( WIN + R > outlook.exe /safe ) - didn't work

    5.) Tried disabling firewall and overall whole antivirus - didn't work

    6.) Tried to add different mail attached file in control panel > email - didn't work as well

    7.) tried to update registry for outlook ( HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\OFFICE\OUTLOOK\PST PROMPT REPAIR. ) - didn't work

    8.) tried to use external .OST file recovery program that was recomended on the internet - didn't work

    9.) tried to remove all of the .pst files that was found on my Computer hard drive - didn't work

    10.) I removed a file from appdata - didn't work

    I basically tried every single way that i found on the internet to fix it but nothing seems to be working. Can you guys help me found a solution for this? I'm experienced IT user but i simply can't fix this. I tried everything. Literally everything.. 

    Thank you for everyone that responds. Have a nice rest of your day :) 

    BR

    Michal

  • Hi ,

    What's the version of your Outlook 365? (File > Office Account > About Outlook). Please make sure you have upgraded your Outlook to the latest version.

    >> From today i have been experiencing, that my outlook can't run, because a message is always showing up.
    Do other users in your working environment have the same issue as you?
    Does this issue only happen to your O365 Exchange account? It is suggested to add other personal email account to your Outlook and see if this issue could be reproduced.

    To confirm if your issue is related to your Outlook client, please log in to your web mail and see if they can work all fine.

    >> I basically tried every single way that i found on the internet to fix it but nothing seems to be working. 
    It seems that you have already tested many workarounds. In order to confirm if your issue is related to the remained files of Outlook, please try the steps below to see if there is any difference:

    1. Exit Outlook and open the Registry Editor
    2. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0
    3. Right-click the Outlook folder
    4. Rename it as Outlook1
    5. Restart your Outlook and add your email account to test

    (Note: Serious problems can occur if you modify the registry incorrectly. Before making changes, back up the registry to restore it in case something goes wrong.)

    Besides, since messages in exchange account are all synced with mail server, it is suggested to completely reconfigure your email account without using old .pst or .ost file and see if there is any difference.

    If the problem still continues, I’m afraid there might be something in your windows which corrupt your Outlook, please try to create a new windows profile and see if it works.

    Hope this can be helpful.
