Outlook 2007 .ost limit... cant find the registry entry!

Hi
I have an Outlook 2007 installation which is running a .ost which has hit its 20GB limit. looking to increase this limit I am following the MS ID 832925 in locating: HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\OST

and changing the 'MaxFileSize'. However this path doesn't exist from '\12.0\Outlook\OST' with the only sub-entry being '\SystemCertificates'

The System is: XP Pro Sp3 working on a domain with Office 2007 SBE OEM

Can anyone please advise?
Thanks.

In the article it states: "Note You may have to create the registry values if they do not exist. If the registry values do not exist, follow these steps to create them."

Thanks Guys... it does yes but instructs the following:

"1. Click Start, click Run, type Regedit, and then click OK.
  2. In the left pane, expand following registry key:

For Outlook 2007
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook"



On the pc in question '\Office\12.0\Outlook'... does not exist. Shall I create from \Office\12.0\Outlook'... onwards?
Have either of you had to do this before?
Thanks

'\SystemCertificates'.

... no '\Office' entry.

I think you are looking at the wrong regisrty entry.

You need to do the changes where the outlook 2007 is intalled.

Shreedhar EtteCommented:
Sorry, the article contain wrong path

Check this:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\OST

Shreedhar... do you mean that if we installed Office 2007 whilst logged onto the local Admin acct that I need to log in as local Admin (as opose to the 'domain user profile') to locate the entry??

Shreedhar EtteCommented:
Hi,

- These registry changes are applicable for the .PST and .OST.
- The article point to two registry paths. You need use the below mentioned path
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\PST
- Then create the required registry's.
- You need to create them logging with the user for who this need's to be effected.
- In the article go to MORE INFORMATION SECTION.

Note: In previous comment I mentioned OST that is PST.

Hope this helps,
Shree

just noticed.. have changed (30) to (30720) etc...DOH!

But still no joy!

Do i have to accept that the .ost has corrupted beyond repair and I have to create a new on?

How big is the current OST file?

MegaNuk3Commented:
I have never seen anyone using an OST bigger than 20Gb and nor would I recommend it.

Have you tried compacting it?

Shreedhar EtteCommented:
Hi,

The vaules are set wrongly.

You need to set 20480 in decimal for the 20GB. Hence for 30GB need to set 30720.

However 20GB OSt is asking for trouble.

Make the registry changes and check.

Hope this helps,
Shree

Try MaxLargeFileSize = 0x00007530  (Hex) which roughly equates to 30Gb

If that fails try compacting the OST with:
Control Panel-->Mail-->Email Accounts-->Next-->Change-->More settings-->"Advanced" Tab-->Offline Folder file settings-->Compact Now

You may also want to look and see if that OST is synching shared folders:

How big is the user's mailbox as seen from Exchange? Hopefully not 20Gb too.

this user is probably opening loads of additional mailboxes and all the non-mail items are getting synched into the user's OST as per my previous post about the shared mail folders...

Hi guys,

Tried all your suggestions with no success but had to accept that the large Ost had screwed the Outlook profile.

What I did was to thin down the Exchange mailbox then junk the Ost... created a new Outlook profile and then synch'ed new Ost over the VPN... let it run overnight and all seems good today!

Is it ok with you guys (Shree & Mega) if I split the points down the middle and award?

Your suggestions were all helpful.
