This morning, a user with a 3.7gb mailbox on exchange 2000 fired up her outlook 2003 and gets the error :

Task 'Microsoft Exchange Server' reported error (0x8004010d): 'There is not enough disk space available for this operation'.

I can't find any settings for a quota on the exchange server, and when i try to remote into her computer and remove old mails to clear up space, i get the error:

The file C:\Documents and Settings\xxx\Local Settings\Application Data\Microsoft\Outlook\outlook.ost could not be accessed.

Mail for the other users works fine, although their mailboxes are much smaller.


Watch Question

standard exchange has a 16gb limit for ALL of your mailboxes combined, can you confirm if you have reached this limit or just under it?

Ive had it before where the whole exchange will fail once it hits this limit and we had to keep archiving the users .ost files into .pst files on a monthly basis just to stay under the 16gb limit.

Is there any free space on her C: drive?  It sounds like her hard drive is full.


hi guys,
i am under the limit on the database size, it is about 7gb total.

it turns out the ost error was caused by outlook being open on her work and home computers simultaneously using exchange cached mode. i shut down one of the copies of outlook and was then able to successfully remove around 30,000 junk mail messages, and then empty the trash. even though i did this, her mailbox size in system manager didn't change.

so now when i open up outlook for her, i get a friendly little box telling me i've exceeded my mailbox limit and i get some auto archive options. new mails are not coming through.

her c: is fine with tons of space: ;but this is all server side anyway i think. the exchange server total mailbox size is around 7gb, and there is lots of free space on the exchange server hard drive.

thank you
you should have a schedule somewhere within your exchange server which will defragment unused space (most firms run it over night with the backup process)

check the space again tommorrow (or manually run the defragment procedure now, but dont if there are a lot of users connected)


just to clarify, when i open outlook, the box i get has the title "mailbox cleanup" and says "you have exceeded the size limit on your mailbox. you can find types of items to delete or move, empty the deleted items folder, or you can have outlook transfer items to an archive file."

but i just deleted over 20,000 spam messages and emptied her trash in outlook.

because she does a lot of work remotely from her laptop, everything has to stay on the exchange server and can't be archived locally to her hard drive.

hope this points you in the right direction:


also lookup eseutil.exe


can i run this without taking mail offline? i am getting file locked/in use errors when i try to use the eseutil program


could i up her quota for a quick and dirty fix? how is that done?

you could setup a .pst file in her user folder on your in-house network and move her mail to that file.  Assuming she VPN's back to the office, she would open the saved mail file locally once it will always remember where it lives so to speak.

I have plenty of detail if you need it.


that might be an option if it can be seamless for her because she uses the desktop computer, laptop on the road, and sometimes webmail and she needs them all in sync. if i could just up her mailbox size on the server that would solve the problem for now. i wasn't aware of the 16 gig total limit until today. the mailbox store is 10gb now. we have around a dozen users, so it might be enough till we upgrade windows/exchange next year.

i'm trying the eseutil program now to see if that solves the current problem.

fpcit: she does not log into the domain, and the vpn is via openvpn on a unix machine at the datacentre. i don't really understand the approach you suggest. do you have a link to a description of it?

i guess if eseutil does the trick, that will be the accepted solution unless somebody knows how to up the mailbox size on the server for an individual user (seems to be capped at 4gb). i'm new to experts exchange so if i'm doing anything wrong please let me know.

thx a million


i just finished running eseutil with the store offline. it completed successfully, but when i went to exchange system manager, her mailbox size was the same: 3,736,999

the mailbox store mounted fine, then i fired up outlook on her computer, and the same mailbox exceeded wizard started up right away. so i'm still in the same spot


is there a way to up this user's limit to 6gb? this would solve the problem.
here you go:

apologies for not replying sooner I was flying.

The esutil program would have marked the free space there was as writeable, the mailbox itself wouldnt shrink but the user would have been able to login, because it didnt make any difference I can only assume that her mailbox is in fact using the 3gig so there was no free space to overwrite.

the above link will explain how you can up her limit.

IF your exchange ever hits the 16gig limit your whole exchange server will die and you will have to do an offline defragmentation. the only way of doing this is by temporarily increasing the exchange limit to 17gig (exchange allows you to do this for this sole reason) and that will give you enough free space to start defragging. (search microsoft.com for defraging exchange 2000).

So you should probably make it a weekly check to ensure your not encroaching on the limit

chatsubo info forth coming.


zcrammond: i tried to up her limit using the method described in the document, but the most you can up it to is around 2gb.

very weird that after deleting 20,000 emails and compacting the db it didn't give her any more space.

fpcit: she has access to a windows share over vpn as well as the office.

I'll add one additional comment.  Typically with the PST files I create one for each year for example one for 2007 one for 2008.  I rarely fill a file (about 2GB limited) in a year.  If you do you can rename the files 2007 Jan - Jun and 2007 Jul Aug


ok thanks for all the responses. fpcit's solution worked as i was able to move the data into a local pst and reduce her online store size, eliminating the error in outlook.

We also had similar problem, however, it appeared that this issue was not due to Email Quota, Disk space or corrupt OST file. User had FAT32 file system, which support maximum file size of 4GB.

After converting File System to NTFS, the problem got resolved.

Just for posterity here...  I had this same issue that came up when our EFS DRA certificate expired and it took a couple days to get the replacement in order.  My C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook  folder was something that I had encrypted.  I think that it was trying to create a temp file or something during the download process (hence trying to encrypt it by folder settings) and failing the encrypt, hence generating the error.  This could happen if the normal EFS cert expired as well...

Forgot to add the fix to previous comment was to decrypt the Outlook folder.  In retrospect, I should just encrypt the pst file.  Expired EFS encryption scenarios seem to allow modify and decrypt but not new encryption.
