eM Client 9 introduces synchronized signatures, but Microsoft has released an update to some of their servers which unfortunately locks this feature for Exchange Web Services protocol. If you do not see the 'Synced from EWS' signatures for your Outlooks/Exchange accounts please try this workaround:

• In the Outlook Web Application go to Settings > View all Outlook settings > Mail > Compose and reply.

• After that delete all signatures using the Delete button. 

• Then, in section Select default signatures change values For New Messages and For Replies/Forwards to No Signature.

After deleting all signatures Outlook should create the new signature with the name Outlook Web Signature, which will represent your synchronized signature. This signature should synchronize to your eM Client and can be edited.

Note: in case the Outlook Web Signature was not created, please contact Microsoft support with a request to block Roaming signatures.
