hi

i am using exchange 2010 onpremises i am runing out of disk space its consuming about 4 mb everyday

kindly how to reduce the size of mdb file.

regards

I'm guessing you mean it's consuming 4GB a day, not 4MB?  Anway, is it the size of the database(s) or log files that's the issue?  If it's the database, you can ask the users to delete email.  Other options would be fine tune SPAM filtering (if you have it) to decrease the amount of mail coming in,  move the database(s) to another partition or everyone's least favorite option  - defrag the database(s).  Defragging a database requires downtime.  Now, if the issue is log files and not the database, then are you getting successful backups of Exchange?  If not, that's probably your issue.

Yes, please clarify if it is the mailbox database file (.edb) or the log files.

You could also implement Retention Tags to delete messages older than so many weeks or months depending on whatever policies govern your organization.

Of course, if size if really increasing by 4 GB a day, that option will not be enough.

Hi,

I suggest to refer to the following article for Troubleshooting Rapid Growth in Databases, if its consuming really about 4GB/day, not 4MB/day.

Best Regards.

I hope, you have received enough suggestions to resolve this issue.

A better way would be to checkout the mailbox statistics and see if one is growing at an unusual rate.  If you do have a large amount of white space, you should try to recover it by creating a new mailbox database and move all the mailboxes to it, and then delete the old database.

To make this task more easily, you may get help using this automated application (http://www.exchangemailboxtopst.org/) too that could be a nice alternative approach to PS command.

hi

as i said i have deleted many emails and mailboxes but still

before 2 hours the remaining capacity of the exchange drive was 29.6 gb

now the reaming is 29.4 gb

for your sugestion how do i know if i have larg amount of white space so i can check if moving mailboxes will work.

In the grand scheme of things, that's not a large database.  My suggestion of having user's delete email is more of a band aid than a solution.  When emails are deleted, you won't see the size of the .edb file decrease unless you defrag the database.  If possible, your best option might be to bring another partition online (or use a larger existing partition), create a new DB and then move the mailboxes to it.  Moving the mailboxes will essentially defrag the data so it's even possible the size of all mailboxes could potentially be smaller after the move.

yes you are right

now

can i add a new hardisk and make a new database to this partition.

also i am using exchange standard version which is only allowing you 5 databases.

how to add a new empty database and move the users to it before deleting it.

appreciated you help.

Yes, that's the tricky part.  Because you're limited to 5 total DBs, you'll need to be creative.  Is it possible to collapse 2 other DBs together temporarily?  That would give you 4, allowing you to create the new one.  After you move the mailboxes to the new one, you can delete that one and recreate the other allowing you to move mailboxes back to it.  Depending on how many mailboxes you have it may be a pain, but you don't have many options.  Do you have a second Exchange 2010 server or is this your only one?

sorry if that's confusing.

i have only one exchange server.

how do i collaps 2 DBs together and is there any risk on that , and if i added together the users automaticaly will be moved to the new DB ?

is the old DB after moved the users will be save to deleted?

i have now inside one of the databases the .edb file and many other files like E00res0000A.jrs and many text files

and a folder named catalog data this files are available in other databases but not as many as in this DB.

i think instead moving users from database one to database 2

then deleted database one

then create database one again in difrent partition

then move the same users to database one again.

kindly is there is any precaution do i have to take care of this task before doing it

also

the new partition i am making i will add new hardisk to exchange server then i will create the new DB , is there any problem creating a database in difrent drive than the original one.

appreciated your kind support.

What I meant by "collapse" two DBs together was essentially just perform mailbox moves from one DB to another, that's it.  Once all of the mailboxes are moved out of any DB, that DB can be deleted.  Your DBs can reside on any partition, so creating a new drive/partition and then creating a new DB on that partition is of no concern.  When you create the new DB, just make sure you choose the new partition for it's placement, as well as the log files.  Make sure your Exchange backup process is aware of the new partition and DB; it may find them automatically but I'd just verify that.  It's also important to get good backups after the mailbox moves because of a side effect of moving mailboxes.  When you move mailboxes, the process generates log files in a near equal amount of the email you've moved.  Example... If you move 30GB worth of mailboxes to a new DB, that new DB will now have 30GB of email data as well as 30GB of log files.  When a full Exchange backup is run, the 30GB of log files will be truncated (removed) so you only have the 30GB of email data.  Hope I'm not confusing you, just want you to be aware.
