One of my users (Outlook 2007, Exchange 2010) is having problems with her mailbox; she continually gets the message "Updating Inbox" in the status bar and performance is generally poor. I realise her mailbox is large (4.8Gb) but I'm not sure why her OST file is so huge - it sits at nearly 17Gb. I have deleted it and recreated it a couple of times but in each case it has grown to this massive size. I can understand why her laptop would have problems dealing with a file that size, thus giving the mailbox performance issues, but I'm unsure as to why the file gets that big in the first place. I read somewhere that OSTs are generally bigger than the mailbox, but this seems excessive. Is it? Is there any obvious errors to look for? Nothing untoward is in my event logs. Is my best bet to limit which folders are available to her offline?
Have you tried to use the Compact Now option in outlook to compress the .ost file?
I just came across this looking for a solution to something else and thought it may help. It's particularly referencing Outlook 2007 but the option is there in Outlook 2010 as well.

thanks Barbyf; tried it but the file was up to 17Gb in size and compacting it on a relatively low-powered laptop was sloooow! I've persuaded her to shift some of the 5000 or so messages that were sitting in the root of her Inbox into a holding folder and that seems to be helping a bit...
Have you open your Outlook in safe mode ? Please try the following steps to open Outlook in safe mode and to sort out the problem:
* Go to Start >> Click on Run and type Outlook /safe- >> click ok. * Atempt to send a test mail and check you receive the e-mail fine and check whether the send/receive process completes successfully. * If MS outlook in safe mode works. It means the issue is with one of your add-ins. * Try to disable add-ins,
Go to File >> Options >> Add-ins.
* Click Go for COM-Add-ins and clear the check box for all. * Exit Outlook. * Open your Outlook and try to send and receive an email.
There are a few reasons why the OST may be getting so large. Does the client have the outlook CRM add in installed? if so remove and reinstall, I've read some articles related to the add on causing problems. Does the client have a bunch of large attachments in their mail? See if the client can clean up unneeded junk. A 4.8GB mailbox is getting on the larger side, especially if the client wants to run cached mode. Client education for managing their mailbox is going to go a long way. Is the client truly a mobile user and needs the mailbox offline, online mode may help allot here. In that regard, do you allow clients to connect their outlook client via https/ssl, if so would they really need cached mode? Deleting and letting Outlook recreate is the standard fix for this issue but it seems you've tried that already. Another option would to follow the practices documented in http://support.microsoft.com/kb/932086 and http://blogs.technet.com/b/exchange/archive/2007/12/17/3404552.aspx to limit what is being sent to the OST (I know the articles are getting old but the information is still valid for today's users)

This is still ongoing for this user (as an aside, I - unfortunately! - have others with bigger mailboxes) who are OK. Have just noticed she is getting hammered with Sync Issues (there were several hundred for the last few weeks). The following is a typical entry. Any ideas what is causing it?
15:49:10 Synchronizer Version 12.0.6606 15:49:10 Synchronizing Mailbox 'User Name' 15:49:10 Synchronizing full items in folder 'Inbox' 15:49:10 The following message could not be downloaded (0x8000ffff): 15:49:10 The following message could not be downloaded (0x8000ffff): 15:49:10 The following message could not be downloaded (0x8000ffff): 15:49:10 The following message could not be downloaded (0x8000ffff): 15:49:10 The following message could not be downloaded (0x8000ffff): 15:49:10 The following message could not be downloaded (0x8000ffff): | | yadda yadda yadda * several hundred lines (it differs)... | | 15:49:24 The following message could not be downloaded (0x8000ffff): 15:49:24 The following message could not be downloaded (0x8000ffff): 15:49:24 The following message could not be downloaded (0x8000ffff): 15:49:24 The following message could not be downloaded (0x8000ffff): 15:49:24 The following message could not be downloaded (0x8000ffff): 15:49:24 The following message could not be downloaded (0x8000ffff): 15:49:24 Done

Unfortunately, she is mobile and insist on having everything online at all times. I'm loathe to shipping it all out to PST files as they are a nightmare to manage...
