Activate and deactivate G DATA Transport Agents in the Exchange Transport Service

G DATA Exchange Mail Security installs so-called agents in the Microsoft Exchange transport service. These are needed to report all mail traffic within Microsoft Exchange.

If required, you can find further information on the transport service at the following link: https://learn.microsoft.com/en-us/exchange/mail-flow/mail-flow?view=exchserver-2019

This article explains how to manually activate or deactivate G DATA agents

For test purposes (e.g. in the case of problems with mail transmission) it can sometimes be useful to temporarily deactivate these agents in order to be able to exclude them as a possible source of problems. It also makes sense to temporarily suspend the mail check during the installation of Microsoft Exchange updates.

Never forget to reactivate the agents after deactivating them. Otherwise a mail check can no longer take place!

Deactivate G DATA transport agents

Start an administrative Exchange shell.
Execute the following command to disable the G DATA transport agents:
```
Get-TransportAgent -Identity "G Data*" |Disable-TransportAgent
```
Restart the Microsoft Exchange Transport service with the following command:
```
Restart-Service MSExchangeTransport
```

Activate G DATA transport agents

Start an administrative Exchange shell.
Execute the following command to activate the G DATA transport agents:
```
Get-TransportAgent -Identity "G Data*" |Enable-TransportAgent
```
Restart the Microsoft Exchange Transport service with the following command:
```
Restart-Service MSExchangeTransport
```

Check the status of the G DATA transport agents

Start an administrative Exchange shell.
Execute the following command:
```
Get-TransportAgent -Identity "G Data*"
```
You will see a list of G DATA agents installed in the transport service. Check that in the "Enabled" column. True is displayed.
