Data file check in progress

spectrum17 used Ask the Experts™

I opened Outlook today to check mails and I have a little cogs icon which says 'data file check in progress'. I can't send or receive emails.
How do I fix this?
I read there is a scanpst.exe file in the Office14 folder, but it's not in mine. If it's a hidden folder, how do I show it?

First Unhide your hidden files

Go to START/WINDOWS KEY then GO to CONTROL PANEL then find Folder Option press VIEW pick SHOW HIDDEN FOLDER/FILES and then Click Apply and exit.

Folder option
METHOD 1 Outlook in Safemode
1. Exit your Outlook first, and then press WINDOWS KEY + R and type the following in the OPEN UP box

Outlook /safe                             NOTE:  It should be Outlook(space)/safe

You will need disable the following ONE AT A TIME to determine which add-in is causing this issue.

a) Click on File menu, click Options, Add-ins, Go button besides Manage: Com-in Add.
b) Check if there are add-ins listed, clear the checkbox.

Disable each add-in one at a time, restart the Outlook, and repeat the above procedure.

Method 2 Manually start the Inbox Repair tool

Note The file or folders may be hidden so you need to unhide it from the above instruction.

For Outlook 2014 on a 32-bit version of Windows

<disk drive>\Program Files\Microsoft Office 15\root\office15

For Outlook 2014 on a 64-bit version of Windows

<disk drive>\Program Files(x86)\Microsoft Office 15\root\office15

You actually should just wait. The "'data file check in progress" is necessary because the PST file is damaged. Showing the scanpst.exe executable won't do anything for you (it's already running, and IT IS part of your Office installation). The bigger your file, the longer it takes (20GB could take up to 6 hours even). You HAVE TO FINISH this check before you can use your Outlook again. Stopping it won't solve your issue.
If your file is VERY large, you should think about making more smaller files, to prevent the long waits in the future (if it gets damaged again, i.e. during incorrect shutdowns or hard disk failure).

First unhide the folder.

•      Start > Control > Panel > Appearance and Personalization > Folder Options > View > Advanced settings > Show hidden files, folder and drives > OK.

After that to find the location of folder office 14 in Outlook 2010:

32-bit Windows: C:\Program Files \ Microsoft Office \ Office14\
64-bit Windows: C:\Program Files (x86) \ Microsoft Office \ Office14\
64-bit Windows: C:\Program Files \ Microsoft Office \ Office14\

Thank you all for your comments. Kimputer, you were right, it's managed to fix itself and the 'cogs' have disappeared. In saying that, I now can't send and receive anything.

So Juliet I've tried the disabling the add in's as per your notes (which were great by the way) and it still won't send and receive anything.

Any idea's what else I can try?
Also check if the PST file in question is over 4GB (check the location first in Control Panel > Email > datafiles, then open location and check size) AND your filesystem is FAT32 (This PC/Computer > right mouse click on the hard disk where the PST file resides, most probably C:\ > Properties > Read what's behind File system:).

If PST file bigger than 4GB and file system IS FAT32, it's a filesize limitation.

Close Outlook
Rename the PST file (you can load it up later in Outlook).
Control Panel > Email > datafile > Add (make a new PST  file with the EXACT same name as the previous file, in the same location)
Start Outlook, email will come in again, BUT in an empty file, as you started over. The old PST file can be loaded now, but it will be seperate (an extra under your current folder), and can only be used for reference, not for adding stuff


On your PC, convert your disk to NTFS with a administrative cmd box (if drive in question is indeed c:\):
convert c: /FS:NTFS
Probably a restart of your system is now necessary. Wait for a while again while the system boots.
Hi spectrum17,

1st method

Verify first if the outlook was offline

*On the Outlook menu, make sure that Work Offline is not checked.

CLick Tools>Account Settings>Change your profile>More Settings>Advanced.

For Hotmail users make sure you have these settings:

Incoming Server (POP3): 995 ( Tick This Server require an encrypted connection SSL)
Outgoing Server (SMTP): 25

Use the following type of encryption connection: AUTO Make sure AUTO is selected as this is what makes the difference

*Check if the credentials are all correct


Kimputer, it was the size! The file size was near 4GB. I've archived and now all is working again. Thanks for your help everyone. :)
