The current physical size of this database (the .edb file and the .stm file) is 52 GB. This database has exceeded the size limit of 48 GB. However, the logical free space in this database has not yet been evaluated. Therefore, it is possible that this database contains enough free space to bring its logical size below the maximum size limit.

If the logical database size exceeds the maximum size limit, it will be dismounted on a regular basis.

We have been running Mailbox Management Process to clean deleted and old e-mail messages based on the Mailbox Manager Settings Policy; however,  I think, there is a lot of white space.  In addition, the disk space on the server is  limited.  What is the best way to resolve this issue?

    If disk space is limited on the server you may struggle to do an offline defragment as it needs to create a tmp database which will be the same size. I have had great success with offline defrag's so if you have the space then its the best way to go. The mailbox management process I have found in no way compensates for a full offline defrag. I would increase the database size to give you some breathing space as a store dismounting should be avoided.

    How about mapping a drive from different server and then peform the defrag.

    Mapping a drive would work, but if there is a network issue that can cause problems.  I'd use a local USB drive before I'd use a mapped drive.
