During the installation of SMSMSE and credentials to set up the SMSMSE service account were entered. The installation produces an error "User does not have a mailbox, please change username or create mailbox for the user".
Username or domain for the SMSMSE service account contains a space.
SMSMSE is not properly escaping the space character when checking the mailbox using Exchange Management Shell.
This issue is resolved in SMSMSE version 6.5.1 and higher.
Specify a user account that does not contain a space in the name.
