Reason Behind Not Showing Attachments
The reasons for the issue can be various from Outlook settings to interference from antivirus programs. Among the most frequent ones are the following:
- Firstly, for safety reasons, Outlook can block some attachments such as.exe,.bat, or.zip, and you may not see them at all.
- Secondly, if the PST or OST file was corrupted, the attachments associated with the emails that were stored in such a file should not be shown too.
- Thirdly, the security software can keep attachments that they think are unsafe in a special quarantine, due to this you may get invisible attachments.
- Fourthly, the use of add-ins that disrupt the usual loading of emails can prevent you from viewing the attachments.
- Temporary files for attachments are stored within the user’s Outlook.
- A full or corrupt cache can cause the attachment not to display accurately.
- When your account does not sync properly, attachments may fail to download from the mail server.
- Sometimes, customized or filtered view settings can inadvertently hide the attachment.
