Supported platforms and requirements
CodeTwo Email Signatures for Office 365 consists of several components that are responsible for handling server-side and/or client-side signatures. The core portions of the software that seamlessly process emails and apply signature rules, e.g. the CodeTwo Email Azure Service, run on Microsoft Azure servers and are operated by CodeTwo.
The administrator of an Office 365 tenant configures the software via the CodeTwo Admin Panel: a web-based panel for registering new tenants to the service, managing payments and accessing other tenant-related options. To manage the signatures, the admin (or the users delegated by the admin in the Admin Panel) needs to launch a dedicated Windows app – the Manage Signatures App.
Outlook users need to install the CodeTwo Signatures Add-in for Outlook on their machines to have access to client-side signatures. An optional component, the CodeTwo Email Signatures for Office 365 Add-in, allows end users to preview server-side signatures while composing emails in Outlook and OWA.
The last component, CodeTwo Email Signatures for Office 365 Custom Attributes Sync App, is required only if you want to use custom AD attributes in email signatures.

|The following message types are only supported in client-side mode (and in combo mode for client-side signature rules):
Messages digitally signed and encrypted via Office 365 encryption / Azure Information Protection (Azure RMS and related features: Encrypt-Only, Do Not Forward, sensitivity labels) or by other encryption technologies (e.g. S/MIME, PGP or OpenPGP such as GPG) are supported in client-side mode and in combo mode for client-side signature rules.
In server-side mode, encrypted/digitally signed messages will be stamped with signatures only if encryption takes place after these messages pass through the CodeTwo services. The same applies when using server-side signatures in combo mode.
|Out of Office messages (autoreplies) are not supported.|
