Zimbra connector for ARM CPU

[malcolm10x]

Is there a Zimbra connector for the new ARM-based MS Surface Pro X ARM processor?

I'm using Outlook 365 (all up to date as of 3 January 2019) on W10-64 (which is also up to date).

Installing the 64-bit connector 8.7.10.1711 with server 8.7.11_GA_1854 complains it is not ARM-64 compatible, needs to see an x64 Intel CPU. This is not unexpected for ARM-64: I was forewarned.

So I reinstalled O365 as 32-bit and tried 32-bit connector (32-bit apps are supposed to be compatible and most are). Now connector installation is complaining that CTR is not supported. I've seen this before caused by remnants of old, pre-installed O365 software, but that doesn't seem to be the case here.

I'm sure I've omitted stuff or been less than clear. Ask away.
