Microsoft has introduced Exchange Server in the year 1993. These files came into existence with the introduction of Exchange Server. However, the most common issue that raised by the many user is Exchange EDB file too big and it requires compression. Here, in this blog, you will get to know how exchange database size has grown too big and how the size can be reduced.
Why Exchange EDB files becomes too big?
The exchange EDB files will automatically grow in size as the data within the EDB files increases. However, the EDB files will never compress if the data is removed from the database. Let us suppose that the size of the EDB file is 15GB and if we delete 5GB mailbox or move it to any other database then the size of EDB file will remain as it is, i.e., 15GB. However, 5GB white space will be created in the database and that space will be available for the new data to be written without the increase in the file size of the database. However, the size of the database can be reduced easily with the below-mentioned solutions.

Solution 2: Run Eseutil to Defrag EDB Mailboxes via Exchange Management Shell
If your EDB file keeps growing to large file size abnormally and so you are willing to reduce to the file size, then there are few pre-requisites that must be fulfilled beforehand.
The database of the EDB file must be dismounted before initiating the defrag procedure. However, while defragging is under the process, users would not be allowed to access their emails at any cost.
While the process is in working state, a new file will be created. However, the old file along with the new file as well as the temporary file generated by Eseutil will also exist on your system. There should be enough storage space exist on drive son that it can enable the defragmentation procedure in order to perform successfully.
However, if there is a not enough storage space exist on hard drive then different location can be specified while executing Eseutil command.
- In order to perform defrag procedure, you have to launch Exchange Management Shell and then execute the below mentioned command to dismount Mailbox database.
“C:\ Windows\ system32>cd D:\ Mailbox\ ‘database name’”
“D:\ Mailbox\ ‘database name’> Dismount-Database ‘database name’”
- Run Eseutil for defragging the EDB file
“D:\ Mailbox\’database name’>eseutil /d ‘database name’.edb /t\\ testserver \defrag\temp.edb”
- After, execute the following command to mount the database:
“D:\ Mailbox\ ‘database name’> mount- database ‘database name’”
After performing the above steps, the database size and the existing white spaces on the selected mailbox database can be easily examined. Then you can notice that the EDB file is compressed and all the white spaces are removed from the database. With these steps, the Eseutil execution is done successfully and you can then easily run full backup of the database.
Note: You should have free disk space of at least 10 percent the size of the EDB database that you wish to defrag.
