Android Enterprise - Which PIM solution?

Hey guys,

as of Android 10 being released i am about to move our environment to Android Enterprise and i like to know which PIM solution you use and are happy with?

My first tests are as following:

- Sophos Secure Mail has no possibility to be configured via SMC admin portal (missing configuration)

- Gmail doesnt work at all (wrong password when trying to connect to our Exchange)

- Samsung Mail is not bad but doesnt inherit a calendar or contacts

- "Email+" which is from another EMM distributor doesnt work with SMC
