Office 365 with two CuC clusters and Single inbox

[davearnold21]

Hi

I am about to begin migrating a customer from CuC and CuCM 9 to 11.

As I will be doing this on a site by site basis both clusters will be operational at the same time.

Are there any issues / caveats with using single inbox with two clusters at the same time as they will be using the

same Office 365 accounts ?

The same service account but with non-overlapping CUC subscriber mailbox accounts? That should work. Or at least, I’m not aware of issues with that setup.
