Outlook is corrupting PDF and office documents

Question

The title says it all.... I first get a message that I don't have permissions to the file. I click on it again, and it opens. The next time, I get an error message that the file is corrupt and can not be read. This is true both on the web and on the classic version of Outlook.

It sounds like you are experiencing issues with opening PDF and Office documents in Outlook, where you receive permission errors and corruption messages. Here are some potential causes and solutions:

1. Antivirus Software: Sometimes, antivirus programs can interfere with file access. In your case, turning off real-time scanning in your antivirus (like McAfee) has helped in the past. Consider keeping it off temporarily while troubleshooting.
2. Corrupted Outlook Profile: A corrupted user profile can lead to issues with file access. You might want to create a new Outlook profile and see if that resolves the problem.
3. File Size and Type: If the attachments are large or of certain types, Outlook might struggle to handle them. Ensure that your mailbox isn't too full and that you're not trying to open unsupported file types.
4. Updates and Repair: Ensure that your Outlook and Microsoft 365 applications are up to date. Sometimes, installing the latest updates or repairing the Office installation can resolve these issues.
5. External Content Loading: If Outlook is trying to load external content (like images in emails), it might freeze or cause errors. Try disabling this feature in the settings.
6. Add-ins: Conflicting add-ins can also cause issues. Try disabling any unnecessary add-ins to see if that helps.

If these steps do not resolve the issue, you may want to consult the Microsoft Community for further assistance.
