Hi all,
we have a XG (SFOS 17.5.10 MR-10) and configured the access to Exchange2016 Webmail, which is working fine so far.
But, if I try to upload a Attachement from Outside the LAN, the Upload stuck on attachments larger than 1,x MB.
Inside our LAN or if I'm connected with VPN, i can upload add these attachements without any issue.
I also tried to temp. disable the Exchange-security (Exchange general), but the issues is still there.
Any suggests what I have to do?
Many thanks
Marcus
