I just did that export. &nbsp;the PST is 700MB. &nbsp;Looking at the proprerties in outlook (right click on the folder, choose folder properties, general, folder size, it says it's 200MB?! &nbsp;I opened the PST, checked the properties and it comes in at 500MB?! &nbsp;Would you think they shoudl be so wildly different?<br />
<br />
I use beyond compare to compare files and it can do binary compare of 2 files to see if they are identical / different.<br />
<br />
Is there a way to compare 2 PSTs for the same content?
</div>


<div>
uh, wait a minute... when exporting to pst, it defaulted to the old file name form a backup in March. &nbsp;and I chose 'allow dupes'. &nbsp;so that's not accurate comparison. &nbsp;redoing it now.
</div>


<div>
mark - you know where that 12 months setting in outlook 2010? &nbsp;I don't see it.<br />
<br />
And the OST is 426,081KB<br />
The backup PST is 405,993KB<br />
&nbsp;<br />
The properties in outlook say the total folder size is 266KB.<br />
<br />
here - check this out - checking folder size in outlook, you have 2 tabs - local and server. &nbsp;would you think server would be the same or bigger than local? &nbsp;(not caching everything would mean server is larger?). &nbsp;BUt for some of my folders, local is larger than server.<br />
<br />
any thoughts on that?<br />
<br />
I am compacting (the OST?).<br />
<br />
so is there a way to compare 2 PSTs for the same / different content?

<div>
thanks, but I have outlook 2010.<br />
<br />
check out these pictures. &nbsp;should local and server data size be the same? &nbsp;why different, even after compact now on the local machine?<br />
<br />
Server shows stuff in the inbox. &nbsp;I went to office365.com, logged in and it shows nothing in the inbox (we are just using this account for contacts / calendar. &nbsp;I guess it might send mail internally, but I'm not seeing it.<br />

Carbonite for Server supports Exchange 365 currently and we have plans to support the other parts of Office 365 down the road. Once you authorize Carbonite to access your Exchange365 backup we just pull the data on a schedule you select and keep the data for a retention period that you also select.<br />

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
