Support for hybrid environments
A hybrid environment allows businesses to reap the benefits offered by on-premises Exchange Server, as well as Microsoft 365 (Exchange Online). However, mail flow and email signature management in such an environment can be tricky, especially when you have mailboxes split between the on-premises and cloud environments. Still, there is a convenient solution to this problem – CodeTwo Email Signatures On-prem.
The program allows centralized management of email messages in hybrid environments with centralized mail transport enabled. By routing all emails through your on-premises Exchange Server, where the program is installed, you can also manage messages sent by Microsoft 365 users. In this scenario, you will be able to manage all user mailboxes in your organization if:
- all mailboxes are located in the on-premises part of the environment, or
- the mailboxes are divided between on-prem and the cloud.
In the case of hybrid environments where user mailboxes are hosted only in Microsoft 365, you can use our email signature and disclaimer management software – CodeTwo Email Signatures 365.
CodeTwo Email Signatures On-prem also supports the Sent Items Update (SIU) service that lets a user see the added signatures in the Sent Items folder. This will work regardless of whether the email was sent from Microsoft 365 or on-premises Exchange.
