I have a user that has a large Outlook 2007 OST file. It was over 4 gigs... We got it down to 1.7 gigs. The problem she is having is anytime she logs into OUtlook 2007 it always starts out by updating Inbox with 150MB of data.. regardless if there is emails to be downloaded or not.. Currently using Cached mode... Cannot use online mode with our current internet speeds.  She has to constantly click send / receive to get new emails to download or exit outlook and log back in.. when she does this it still looks to download 150MB of data.  Please advise.

thanks

You could delete the .ost file and let Outlook create a new one from scratch. Still painful, as it will (eventually) download 1.7GB.

If that doesn't help, I would wipe the Outlook configuration and start setting up Outlook as if you were using it the first time.

Use a filter to restrict the items that you synchronize from Exchange to your .ost file
To configure a synchronization filter on a specific Exchange mailbox folder, follow these steps:
1.Right-click the folder, and then click Properties.
2.In the Properties dialog box, click the Synchronization tab.
3.On the Synchronization tab, click Filter.
4.In the Filter dialog box, specify the criteria that will be used to synchronize new items that you want to arrive in this folder.
5.Click OK two times to return to Outlook.
Note This method will reduce the current size of the .ost file. Items that were previously synchronized in this folder will be removed from the local copy of your .ost file the next time that Outlook synchronizes this folder. These items will be removed if they do not fit the filter criteria. You may have to wait for background compaction to occur before you can see the size of your .ost file decrease. Alternatively, you can manually compact the .ost file by clicking the Compact Now button in the Advanced settings of the Exchange account.

If you use a synchronization filter, you can view the items that are not synchronized with the .ost file either by using Microsoft Office Outlook Web Access or by using an Outlook client that is configured to use online mode in an Outlook profile.

If you use a portable computer
If you are using a portable computer, you may experience these problems sooner than you would on a desktop computer. This occurs because hard disks on portable computers are generally slower than hard disks on desktop computers. The performance problems are directly related to hard disk speed

Are you certain you recreated the entire profile from scratch?
Control Panel->Mail->Show Profiles
Delete her profile
Create a brand new one
Let it download the whole thing (best to do at the end of the day so it can download overnight).

If you have done this, then there is either something in the inbox causing the error or there's an actual error with the mailbox itself. You could try exporting all her data to a .pst file, creating a brand new email account on the Exchange server, and moving all her data back into that one. If the problem still persists after that, then there must be some item in the inbox.

Here's what I would do. Move all the stuff in the inbox into some other folder. If it says it's updating the other folder, then move half of the stuff back. Keep doing this until you find out which item is causing the problem and delete it. (You could also sort by size and only look at things 150MB and higher). If the inbox is empty and it still says "Updating inbox 150MB" then you'll probably need to fix her actual mailbox on the Exchange server. You could do a repair or just create a new one and delete the old (don't forget to export and import the data).

Please read this whole post carefully and not just the last paragraph.

This could be a mailbox problem on server or outlook configuration problem on PC.

On PC you can try to delete outlook profile, move all data from both outlook folders in user profile (nk2 file most probably you will need to copy autocomplete cache) and recreate outlook profile.
Locations in windows xp:
c:\documents and settings\%user%\application data\microsoft\outlook
and c:\documents and settings\%user%\local settings\application data\microsoft\outlook

If that will not help, then you can try to configure that account on another computer - just to be sure that it is not an original PC problem. If the problem persists also on another PC, that the source of the problem is in mailbox. You can try to check consistency of exchange database or simply try to create another datastore and try to move that mailbox there.

run scanpst.exe on the users data file, and see if it comes back with errors
Are there any issues when accessing the account from web access?

I've requested that this question be deleted for the following reason:

None of these answers helped.. I had to re-create mailbox.

In http:#a36600904 I actually suggested recreating the mailbox as a last resort option.
Also, the other suggestions (in mine and the other posts) are valuable to have in the answer database. I recommend just including a closing comment saying you had to recreate the mailbox so others with that problem will know to do the same.
