Access Portal - Reverse Proxy - OWA: Attachment size limited?

VGBHVGBH
in Firebox - Subscription Services

It is not possible to open or download files larger than 2MB. We are using a on-premise Exchange Server.

For example:
I want to open a PDF file. It is possible to open a PDF file smaller as 2 MB. A PDF file larger than 2MB does not open. I will see an unlimited loading bar. I can´t even Download the file.

With Word/Excel files:
I can´t open this files in a browser, so the browser will ask me to download this files. Files larger than 2 MB can´t be downloaded.

It is possible to open and download this files, when I connect to OWA in LAN. The files are not broken. I tested it with several files.

    Hi @VGBH
    Do you see any error logs for 'portald' or 'guacd' in your traffic monitor when you try to open these attachments?

    I'd suggest opening a support case so that our team can look at your firewall's logs and help.
