I have one user that is having a problem with some of her attachments being blocked by Outlook 2007 in her archive PST.
I am aware that Outlook will block executable attachments but the issue her is that the attachments are normal documents such as .doc, .pdf and .xls. I have only seen it in the PST and not the OST and even then, only on some emails in her PST. In other emails, a .doc won't be blocked.
Things i have tried:
- Editing the Registry to add those extensions to the Level1Remove key. That doesn't unblock the attachment in the PST. Only makes you save files that weren't already blocked with that extension to disk before opening. More on that here
- Editing the Group Policy to allow those extensions and change Outlooks security mode. Unsuccessful and i have reverted those changes. More on that here
- For isolation - Attaching an entire email as a .msg to an email and sending it to another machine and seeing if they could open it. No. The attachments either remain blocked, Come through as empty .txt files or not at all depending on the version of Outlook
- For isolation - Moving the affected email/s to the OST but remained blocked
- Running ScanPST.exe over the archive as i thought it may be corrupt but made no difference
Things i haven't tried:
- Opening the Archive on another computer. I can't do this until Monday when the user gets back from an overseas trip but that should at least tell me whether it is a problem with the archive or with the machine/outlook profile
- Recreating the users Outlook profile / computer profile. With limited access to the users machine at the moment, this may have to wait until Monday
What i can't do:
- The parent company does not use Exchange Journaling for some stupid reason so putting all her historic mail back into her mail store and just letting her download it all again to her OST is not an option. And they only just implemented an online backup solution for the laptops so any backup they have of the PST may have the same issue (if it is a pst issue)
So i want to know if anyone has seen this kind of behaviour and what your thoughts are on it and what i should do and test for. I can resolve it once the machine is back in my possession on Monday but this user is VIP so if there is anything i can do before that remotely then that would be good
I would also like to avoid doing major sugery remotely over a Telstra wireless dongle in case something goes wrong and makes things worse but if you're sure it will fix it then sweet
