The PRE 8.5 signature issued to a user is installed as an HTML file on the user's local hard drive. If a user had been delegated access to send emails on behalf of the mail file owner, the signature was not available to the delegated user.

If the user with delegated access clicks on the installation email, it would install a new copy of the signature and update the Calendar Profile. If the path was generated using the @unique or the %TEMP% directory, then the new path would be different from the Mail File Owner's original installation path

This fix allows the user with delegated access to install the Mail File owner's current signature into the same path as the one specified in the Calendar profile.

This fix was added in V3.10
