If anyhow .stm is missing or any mishap will be happened, u can still recover by this command /createstm switch. the sample comm. is:
eseutil /p priv1.edb /createstm

By using this option for the priv1.edb will the new stm file be created in the same location or will I need to specify a location for the stm file ?

Both need to be defragmented, but when u specify the edb then stm will also be defragmented as well. Before do it, it requires the databases must be dismounted.

Remember, before doing the job, U must take backups the database both like edb & stm to another disk / other safe storage. It helps to recover databases in case disk fails / occur any mishap during the defragmentation process.

I am not concerned by how much free space is required to defrag the DB, that is not an issue.
Time is the issue. As my DB is 65GB then presumably I can expect the defrag to take around 7 hours ?
Do I need to defrag the priv1.stm independently ? Or will defraging the priv1.edb be enough ?

Close information store service. open cmd and type as :eseutil /ms My priv1.edb
Now calculate the free space by multiplying the number of free pages by 4 KB (might be it is 35 gb). and subtract the figure from physical size of ur DB.
Again multiply this amt 110 %.
Note: The sum total is the space that you require to defragment the db
To estimate approx time that is required to defragment the database, divide the figure as per hour.
Reference from Micro Soft

Note 9 GB per hour is the speed at which the Eseutil utility runs.
