Hi,
Apologies if I am posting in the wrong place. I am hoping someone can shed some lights or give me some suggestions.
I have one user, only one user, having this strange issue. She receives voicemail in her email with a wave attachment, but Outlook desktop app blocks this wave file (voice.wav). The attachment is not blocked in OWA. It is not blocked by our mimecast email filtered. It only gets blocked when it hits outlook desktop app.
What I did so far: used Level1Remove reg hack, completely re-installed office suite, logged her onto a totally different machine to see if it was her profile, put in a ticket with MS Support > the result was nothing worked!
I just don't know where else to look. No one has this problem in our organization. The affected user is on Windows 10 20H2. The strange thing here is, once in awhile outlook would let the wave attachment through, but most of the time, it blocks it with the message "outlook blocked access to the following potentially unsafe attachments".
If you have any suggestions for me to try, greatly appreciate it!
Thank you!
