Hello,

We just upgraded from 8.3 to 8.4 and now Exchange Activities have stopped and we are getting this in the error logs -

```markup

Hello&nbsp; @chrisk &nbsp;,

FAM 8.4 uses some enhanced commands suggested by MSFT and requires the EXO V3 PowerShelll module to be installed on the CPC server.

Please verify if you have the latest EXO Module installed.

Thanks.

Ranjith

Hey&nbsp; @ranjith_koppu

We are using v3.1 of the EXO module.&nbsp; We previously had 3.4 but were told by support to downgrade it to 3.1.&nbsp; Still receiving the error.

This is installed on the machine that has the ExchangeOnlineBAM installed.&nbsp; Should it also be installed elsewhere?

Thanks,

Chris
