I am having trouble installing Office 365 on my client machines.
We always get the error 30015-25 when trying to install. I can see on the firewall that all the machine downloads what looks to be like all the required content (judging by the amount of data).
It also takes quite a while to fail.
I am aware that there could be an issue on my Firewall side, but i have no idea what to look for as nothing out of the ordinary is blocked.
Any help would be greatly appreciated.
