exchange 2013, outlook 2013

before trying to move mailbox to a different database, i need to reduce the size.Currently the email box is very hard to work upon, it goes into loop as soon as we open an email. Working on each email itself taking about 10 minutes with such performance moving data from 2012 with each month having an average of 4k to 5k emails is very difficult task.

I don’t think we can move them manually and also I don’t want to take the risk of losing any emails during manual process.

Later, I was able to create a folder in the online archive and then initiated the transfer but in between again the Outlook crashed on my computer. After which I checked the transfer didn’t complete.

As the mailbox has huge amount of emails is there any way I can reduce mailbox size.

sorry we have exchange 2010 sp3
You don't move it.  You should be able to compact it from the Data File windows in Outlook :

How many mailboxes do you need to reduce in size?
Open the suspect mailbox in OWA>click Filter>Sort by Size(make sure the arrow is pointing up so you get the largest emails)if not click it again...you don't want the "tiny" emails

Select one of the emails and then ctrl A(to select all)
Right-Click> Archive
Actually, the compacting may not be what you want because you will require to compact, export, then import to the new DB but it will reduce the mailbox size.

A second thought would be to move the emails from a certain mailbox by date range so you can move partial at a time.  Do you want to move this directly from DB to DB?

I came to know somemailbox data are already corrupted so will compact work?
If the mailbox data is already corrupt from the start then no I don't recommend compacting as it won't fix the initial problem.
Corrupted items will be ignored when you move with baditem limit.

while compacting u mean?
MAS suggestion is probably a good idea so you wouldn't have to deal with bad items manually and it directly move from db to db.
