OST file size is 32 GB

I have a user with a mailbox size on Exchange server of 4 GB and when I perform folder size check the mailbox size is 4GB. The OST file on the laptop is 32 GB.
We are currently using Exchange 2003 Server with Outlook 2010 Clients.
The user has other mailboxes listed for employees that are no longer working for our company.
Thanks....B

Hi Bluem1,
If the user is using Outlook in cached mode, the shared mailboxes will also be downloaded to the OST-file by default. To stop that, disable caching of all shared folders in teh users Outlook profile.
To disable the caching of all shared folders, follow these steps:
On the File tab, click Account Settings in the
Account Settings list.
In the Account Settings dialog box, click the E-mail
tab and then double-click your Microsoft Exchange Server account.
In the Change Account dialog box, click More Settings.
In the Microsoft Exchange dialog box, click the Advanced tab.
Click to clear the Download shared folders check box.
This will not shrink the OST-file, so I would recommend that you recreate it (just remove the OST-file and a new one will be created when Outlook is started). To manually shrink the file using the method in the above linke provided by Peddy1st will take
many many hours.

Possible to increase Outlook OST/PST size to 200GB?

Hi all,
I wanted to know per the subject if it's possible to increase the OST/PST limit to 200GB? If so, would anyone be kind enough to post the values so I can amend a reg key?
Thanks

Hi,
There are two format of Outlook data file. In theory, maximum Unicode pst/ost file size is 1TB or 1024 GB. The maximum file size for
ANSI pst is 1.9 GB.
To increase the maximum size of Outlook data file, please refer:
http://support.microsoft.com/kb/832925
http://www.slipstick.com/outlook/config/changing-the-default-pst-and-ost-sizes/
Please note, if your Outlook data file is too large, it may cause some unexpected issue. So it's not recommended to create a large Outlook data file.
Hope this helps.

Outlook OST file become large

Hi,
My mailbox about 3GB, but the OST file size seems 38GB.
After recreate new OST, it grow very fast back to very huge file size.
Any idea of this?

Hii,
MS Outlook File grows as you create and receive items. Sometimes user of MS outlook encounter an error that OST file exceeded its default maximum file size while sending
and receiving emails. Deleting some data item from OST file might not decrease the file size in proportion to the data that you deleted.
To reduce the size of ost file you can either use Synchronization Filter method or you can
compact the size of ost file on advanced tab settings of exchange account. Synchronization filter Method restricts particular data items to be synchronized from exchange mailbox to ost thereby reducing the size of ost file at some extent.
Steps to be followed for Synchronization filter method,
Right click on folder and click
properties
Click synchronization tab and then click
Filter
Now provide the appropriate criteria for filtering that you want according to what data items should arrive in folder.

How to deal with the extremely big *.ost files in a Terminal Server environment which is running out of space

Hi,
Our Terminal Server is running out of hard disk space, and the major files which occupy most of the space are *.ost files of the Outook, which come form the users which use the Terminal Server all the time through remote desktop. The Outlook is installed
on the Terminal Server and various users can use it.
What would be a solution in this case. Is there a way to limit the size of the *.ost files? I read in forums that having the Outlook 2010 set up in Cached Exchange Mode isn't the best practice for an environment where the hdd space is a major constraint.
What do you suggest?
Thanks,

Is the Exchange server local or remote? If it's local then it might be worth considering disabling cached mode, since the traffic will be going over the local network and therefore having the data cached becomes much less useful. If it's a remote exchange
server then realistically turning off cached mode would likely make it unusable.
If Exchange is remote then other than increasing the available storage, another option might be to upgrade your Outlook / Office installation to 2013. In Outlook 2013 you can configure how much of the users mailbox is cached in terms of time, so for instance
you could set it to only cache the last 6 months worth of mail, and then all recent messages would continue to be quick to view, but older messages that are less likely to be accessed frequently would have to be downloaded from Exchange each time since they
would no longer be cached.

Outlook 2010 - Data File Properties/Folder Size verses Windows Explorer pst file size

I am running Outlook 2010 32bit Version 14.0.6129.5000 on a Windows PC running Windows 7 Professional. All updates from MS are up to date.
I have several pst files I open with Outlook 2010. The size of the files displayed in Outlook are very different than what is displayed in Windows Explorer.
For example one of the pst file called "business.pst" when opened Outlook displays it under "Data File Properties -> Folder Size" that the Total Size (including subfolders) is 764,354 KB. Windows Explorer says
the file size is 1,190,417 KB.
For some reason MS Outlook 2010 is displaying the wrong folder size. Any ideas why this is the case?
Thanks,
Pat

Outlook mailbox grows as you create and receive items. When you delete items, the size of the Outlook Data File (.pst and .ost) file might not decrease in proportion to the data that you deleted, untill it has been compacted.
Normally, after you have deleted items from an Outlook Data File (.pst), the file will be automatically compacted in the background when you’re not using your computer and Outlook is running.
For an exception, when the Outlook Data File (.pst) is somehow corrupt, the compaction might not finish correctly. So the size of the Outlook Data File (.pst) file might remain the same before compaction.
To solve this, try run the
scanpst to fix the Outlook Data File (.pst) file first, after that, we can
manually start the compact command.
When finished, compare the file size again.

Can we script the compressing of OST files on users computers

After mailbox cleanups either manually by users or by using archiving software OST files remain large. Couple of questions. If the user does nothing, will Outlook 2010 automatically try to compress the OST file in the background? Read some things that seem
to suggest that once the white space grows to 20% of the total size of the OST, Outlook will start a process that runs in the background to compress the OST.
If this is true, can this value of 20% be adjusted. If it's not true, is there any way to programmatically compress the OST so the user does not have to do it manually, or delete the OST and let it rebuild?

Hi,
There's no such method to change the threshold of 20%, but we can configure Outlook to automatically compact the .pst or .ost every time we close Outlook.
I don’t actually recommend this method, as it can lengthen the time it takes Outlook to shutdown and if Outlook is forced to close during the compaction process the data file could become corrupt. My suggestion is that if the .ost file is not so large,
just leave it alone.
If you are sure you want to do this, you can add PSTNullFreeOnClose to the registry.
Important
This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the
registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry,
http://windows.microsoft.com/en-US/windows7/Back-up-the-registry
Press Win key + R and type "regedit" in the Run dialog, then press Enter to open the registry editor.
Browse to the appropriate key for your version of Outlook, in your scenario it's Outlook 2010, the key is "HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\PST"
If the PST subkey does not exist, create it.
Right click on PST key and choose New, DWORD.
Type (or paste) PSTNullFreeOnClose as the Name.
Double click on it and enter 1 as the Value.
DWORD: PSTNullFreeOnClose
Value Data: 1 = compact on close, 0 = don’t compact
Although the key name only contains "pst", it also works for .ost files.
I hope the information can be helpful.

How to pad OST file to prevent fragmentation

Does anyone have any clever tricks on how to quickly fill then empty an OST file, so you can get it to what your maximum mailbox size in, then clear out the padded space so it has a ton of free space in it, and the file will no longer become fragmented then.
We have performance issues once large OSTs get heavily fragmented due to them constantly expanding as more and more email builds up, so was wondering if there was a way to grow it or pad it to make it the max their actual mailbox could get, then free the
space from the garbage files.

Hi RJ022,
Yes, I agree with Daine that compacting a file just help to reduce only approx 20% of white spaces in the data file. But, if you really want to solve this large OST data issue, then you should prefer archiving
instead of this one. It will help you to make an archive of Outlook data file and reduce the risk of damaged data and slow Outlook interface.

Óutlook - Disable OST file creation.

Hi.
Running XenApp 6.0 on Windows 2008 R2 with Office 2010
Some users has managed to enable Offline use so there are created a OST file in %USERNAME%\AppData\Local\Microsoft\Outlook
In group policy we have disabled this:
Use Cached Exchange Mode for new and existing Outlook profiles
So it is not possible for the user to enable Cashed Exchange Mode under Account Settings.
But still the user can go to Account Settings, select Data Files pane and select Settings.
Then select Advanced pane and "Outlook Data File Settings..."
Here you just hit OK at then the sync starts after an Outlook restart.
Is it possible to disable this feature?
Thanks
Torsten

Hi,
As I have tested in my environment, the size of local ost-file didn't increase when I followed your steps. So, would you please tell me how did you notice that the sync starts after an Outlook restart?
In theory, Outlook will work using information directly from the server when you are in Online Exchange mode. It won't sync anything to the ost-file.

Office365 - OST download size and managing it.

We have 400 users and we are using Microsoft Office365 Enterprise (E3). The mailbox size of few users more than 25GB (Just 3 months data).
If the user moves from one computer to other, the entire mailbox will be downloaded via internet. This consumes high bandwidth. In case more than 3-4 users shift per day, all other users experience slow internet access.
I have read the performance blog:
http://blogs.technet.com/b/askperf/archive/2007/01/21/network-stored-pst-files-don-t-do-it.aspx
So, will not be trying to re-direct OST/PST files to network location.
Requesting some experts advise to overcome this problem.
Thanks.

Hi,
If your mailbox is large, a larger OST file is needed to download to your Outlook when changing your computer. When you don’t want to use Outlook in Online Mode as a workaround, I suggest we can try the following method to manage your OST file:
1. Delete Items or archive items in your mailbox to reduce the size of the Exchange mailbox.
2. Manually compact OST files to eliminate deleted item space in Outlook:
http://support.microsoft.com/kb/289987/en-us
3. Limit the amount of email synced to your OST by using a filter to restrict items.
For more information about these methods, please refer to the following KB:

Exchange Online forum for more professional answers.

PDF File Size - any way to compress further?

We have are using the Crystal for .NET export method to export a report to a .pdf file, and are having an issue with the pdf file size on a report that contains images. The images are stored in a SQL2005 database as blob or varbinary(max). The report executes a stored procedure that selects data (including images) to produce a quotation. There are input parms to decide which images to print (for example A, B or both A&B). Both types of images can appear at the line level on the quotation. Type A images print in the main report, Type B images are in a subreport. Both the main report & subreport execute a stored procedure to select an image type.
Our issue, when both Type A and B image is selected to print on a 293 line quote. The PDF file size is 44.23MB
When Type A only is selected, the PDF file size is 2.64MB
When Type B only is selected, the PFD file size is 43.95MB.
There are more Type B images that would print at the line level than Type A, but is there any way to compress this down further as it is too large to email.

You mention that you are using Crystal for .NET, but not what version; CR for .NET 2003, 2005, 2008. 2010?
Applying the latest fixes for the correct version of CR would be the first thing to do.
Next, I'd have a close look at image B as it appears to be the one adding the most "bulk". How is this image different from image A?
General tips re. images:
Save the files a BMPs.
When .jpg image is inserted into Crystal Reports it is converted into bitmap format and as the result of the conversion the report may loose some quality, scale and other issues may arise... E.g.; Crystal Reports is not so good a graphics management tool
When an image is saved as a .bmp, then there is no conversion required and thus the quality of the image should be preserved.
Best practice: save the image with high resolution and required size as a .bmp format then insert this image into Crystal Reports.
Resize the image to the smallest possible size and downgrade the DPI to 72. This will ensure your image is as small as possible and Crystal Reports will have to put in the least amount of work to display it.
Have a look ar KB [1241630 - Exporting a Crystal report (XI) to PDF generates a big PDF file|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233343331333633333330%7D.do]. This KB, may apply to your version of CR, or not. In any case, you will have to use the KB as a guide and determine what the appropriate registry entry would be for your version of CR.
One more thing. Many people like to use jpg files as they are smaller than bmp files. However, as far as Crystal Reports is concerned, this is inconsequential. The report file will be the same size if a file is inserted as a jpg or a bmp. This is due to the jpg conversion to bmp Crystal Reports does internally.

How can I use one background jpeg in my ebook without a large file size

I'm guessing that by simply adding a background image or watermark by default adds a separate copy to each page. Since I am intending for them to be the same on all pages except for the title page, how do I shrink the final file size of my PDF eBooks so that the image is stored once but shown on all pages?
Thanks in advance.

Thank you, I understand, yeah, I knew that, my phone is factory unlocked and I am going home, which is obviously not in the States and I am thinking of buying a local carrier there. However, I still have 2 weeks before I leave and cannnot wait to start using my Iphone 4. I thought at least I could use the mp3 player function. So as far as I understand, I cannot activate it without a sim card. I have been using metropcs for about two years and it does not have a sim card. In this case, do I really not have another choice but wait for two weeks to listen to music? My Mp3 player just failed me and I really need to listen to music but on the other hand, while I can use my iphone as an mp3 player in two weeks, I don't want to spend more money on a new one. So, do you have another suggestion? For instance, can I use a friend's sim card to activate mine? Would this cause any trouble, when I go home and buy a local carrier? I think these questions might kinda sound weird to you, but first time with an Iphone, extremely excited to start using under my circumstances, I need help thanks,

A simple and free way of reducing PDF file size using Preview

Note: this is a copy and update of a 5 year old discussion in the Mac OS X 10.5 Leopard discussions which you can find here: https://discussions.apple.com/message/6109398#6109398
This is a simple and free solution I found to reduce the file size of PDFs in OS X, without the high cost and awful UI of Acrobat Pro, and with acceptable quality. I still use it every day, although I have Acrobat Pro as part of Adove Creative Cloud subscription.
Since quite a few people have found it useful and keep asking questions about the download location and destination of the filters, which have changed since 2007, I decided to write this update, and put it in this more current forum.
Here is how to install it:
Download the filters here: https://dl.dropboxusercontent.com/u/41548940/PDF%20compression%20filters%20%28Un zip%20and%20put%20in%20your%20Library%20folder%29.zip
Unzip the downloaded file and copy the filters in the appropriate location (see below).
Here is the appropriate location for the filters:
This assumes that your startup disk's name is "Macintosh HD". If it is different, just replace "Macintosh HD" with the name of your startup disk.
If you are running Lion or Mountain Lion (OS X 10.7.x or 10.8.x) then you should put the downloaded filters in "Macintosh HD/Library/PDF Services". This folder should already exist and contain files. Once you put the downloaded filters there, you should have for example one file with the following path:
"Macintosh HD/Library/PDF Services/Reduce to 150 dpi average quality - STANDARD COMPRESSION.qfilter"
If you are running an earlier vesion of OS X (10.6.x or earlier), then you should put the downloaded filters in "Macintosh HD/Library/Filters" and you should have for example one file with the following path:
"Macintosh HD/Library/Filters/Reduce to 150 dpi average quality - STANDARD COMPRESSION.qfilter"
Here is how to use it:
Open a PDF file using Apple's Preview app,
Choose Export (or Save As if you have on older version of Mac OS X) in the File menu,
Choose PDF as a format
In the "Quartz Filter" drop-down menu, choose a filter "Reduce to xxx dpi yyy quality"; "Reduce to 150 dpi average quality - STANDARD COMPRESSION" is a good trade-off between quality and file size
Here is how it works:
These are Quartz filters made with Apple Colorsinc Utility.
They do two things:
downsample images contained in a PDF to a target density such as 150 dpi,
enable JPEG compression for those images with a low or medium setting.
Which files does it work with?
It works with most PDF files. However:
It will generally work very well on unoptimized files such as scans made with the OS X scanning utility or PDFs produced via OS X printing dialog.
It will not further compress well-optimized (comrpessed) files and might create bigger files than the originals,
For some files it will create larger files than the originals. This can happen in particular when a PDF file contains other optomizations than image compression. There also seems to be a bug (reported to Apple) where in certain circumstances images in the target PDF are not JPEG compressed.
What to do if it does not work for a file (target PDF is too big or even larger than the original PDF)?
First,a good news: since you used a Save As or Export command, the original PDF is untouched.
You can try another filter for a smaller size at the expense of quality.
The year being 2013, it is now quite easy to send large files through the internet using Dropbox, yousendit.com, wetransfer.com etc. and you can use these services to send your original PDF file.
There are other ways of reducing the size of a PDF file, such as apps in the Mac App store, or online services such as the free and simple http://smallpdf.com
What else?
Feel free to use/distribute/package in any way you like.

Thanks ioscar.
The original link should be back online soon.
I believe this is a Dropbox error about the traffic generated by my Dropbox shared links.
I use Dropbox mainly for my business and I am pretty upset by this situation.
Since the filters themsemves are about 5KB, I doubt they are the cause for this Dropbox misbehavior!
Anyway, I submitted a support ticket to Dropbox, and hope everything will be back to normal very soon.
In the meantime, if you get the same error as ioscar when trying to download them, you can use the link in the blog posting he mentions.
This is out of topic, but for those interested, here is my understanding of what happened with Dropbox.
I did a few tests yesterday with large (up to 4GB) files and Dropbox shared links, trying to find the best way to send a 3 hour recording from French TV - French version of The Voice- to a friend's 5 year old son currently on vacation in Florida, and without access to French live or catch up TV services. One nice thing I found is that you can directly send the Dropbox download URL (the one from the Download button on the shared link page) to an AppleTV using AirFlick and it works well even for files with a large bitrate (except of course for the Dropbox maximum bandwidth per day limit!). Sadly, my Dropbox shared links were disabled before I could send anything to my friend.
I may have used a significant amount of bandwidth but nowhere near the 200GB/day limit of my Dropbox Pro account.
I see 2 possible reasons to Dropbox freaking out:
- My Dropbox Pro account is wronngly identified as a free account by Dropbox. Free Dropbox accounts have a 20GB/day limit, and it is possible that I reached this limit with my testing, I have a fast 200Mb/s internet access.
- Or Dropbox miscalculates used bandwidth, counting the total size of the file for every download begun, and I started a lot of downloads, and skipped to the end of the video a lot of times on my Apple TV.

My premiere project file size just went from 190MB to 5.61GB... and now it won't open! Anyone know how this happened?

My premiere project file size just went from 190MB to 5.61GB... and now it won't open! Anyone know how this happened? Or how to prevent it from happening again? Thankfully I saved a backup project of the 190MB file size.

warp stabiliser?

Is the file size of a selected image shown on Adobe Bridge CC 2014? If so, where?

Is the file size of a selected image among the filter categories? Or anywhere else? I know I can find it in Photoshop, but that is cumbersome.

The file size is shown in the Metadata panel.
You can not filter on file size but you can sort by file size.
