Office Standard with O365 E1?

[Vivek_S]

Hi All,

Is there a document anywhere that states the level of interoperability of Office Standard (2013-19) with Office 365 E1?

We have a few Office Standard licences and we are keen to make use of those with E1 rather than paying for an E3 but we are not sure what the user experience compromises would be versus E3. 

Thanks!

The biggest thing I can think of off the top of my head is you will be limited co-authoring and auto save with older versions of office, but other than that, not much besides missing newer features.
