Moved a client over from an exchange server to SM, for whatever reasons, they prefer eM Client. However, this is an ongoing complaint we've had from eM users who use other EWS hosts like O365 or on-prem Exchange, no archive option.

The "Archive" folder on their on-prem host shows as a special folder as shown with the unique icon...

In SM, it's just a normal folder like the others, and the menu option to archive an email no longer shows. Both their on prem account and SM are using EWS.

Can this be added so that users can have the "Archive" option? I am assuming there is something that needs to be implemented on the server end, along with an updated EWS response to indicate that archiving is supported?
