Hi @kerem kendirci
Welcome to our forum!
What is your account? Outlook.com or something else?
Does the issue occur recently on Outlook Desktop Client? Do you have any specific operation before the issue occurred?
To further confirm if the issue is more related to Outlook desktop client, if possible, please log in to your web mail to check if the attachments display normally.
Based on the machine translation, can i understand that you are sending an email with an attachment, but the attachment is not showing up properly in your sent message?
If so, here are some steps you may want to take:
- Use Search: An email with an attachment may be accidentally moved to a different folder (Normally, sent messages are displayed in the Sent folder by default), and you can use the search function to make sure that it actually exists in your mailbox. Also, the Deleted Items folder may need to be checked separately.
- Switch to Legacy Outlook: If you are using the New Version, please try switching back away from the "New Outlook", this may resolve some unexpected problems.
- Update Office: Make sure that your Office LTSC Standard for Mac 2024 is up to date. Updates often include fixes for bugs and issues. You can check for updates by going to Help > Check for Updates in any Office app.
- Rebuild Outlook Profile: Considering data file corruption, it is proposed that you create a new profile, re-add your account to the new profile and check if the same issue still occurs.
Hope it helps!
