Outlook 2010 hangs when receiving last e-mail

I have a customer with a very strange problem. The setup is Windows 7 and Outlook 2010 (POP account). When doing a send/receive in her Outlook 2010, it sends mail OK and (in most cases) starts to receive e-mails (X of Y messages). When it gets to last but one message, that one takes a long time to download and the on the last message a server time out error occurs.

The original .pst file was a massive 26GB, so I archived about 16 GB, into a separate archive.pst file ...... but the original pst file remained at 26GB ??

Exporting that original pst file in Outlook to another pst resulted in that new pst file being about 5GB.

This is what I've tried so far but nothing makes any difference to the original problem:

1) Ran SCANPST - a few errors found and repaired
2) Ran Outlook Repair - completed OK
3) Created two new Outlook profiles (one with e-mails imported from original profile, one with no old e-mails imported) and recreated the e-mail account in both profiles.
4) Extended the POP server timeout to 10 mins
5) Temporarily disabled her Norton 360 AV/Firewall
6) Opened Outlook in Safe mode

In all the above cases, the Outlook POP account is set to leave messages on the server for 14 days.

I am able to set up a parallel Outlook account on another machine (admittedly running Outlook 2016), over the same router and internet connection and it works fine.

Can anyone shed any light on this. It's driving me up the wall.

Thanks

Hi

When archiving the pst it is not giving back the blank space as free space.
Export import Will do this trick.

As to the hanging there can be a view causes, one of them is a harddisk that is starting to fail so a full scan may solve any issues. If it does you know you have to replace this hdd soon.

Another thing is to look at your outlook download setting which probably is set to Download Headers then Full Items.
Changing this to Full Items also may clear the issue.

Thanks for prompt replies guys.

Patrick,

I had already done a chkdsk HDD scan, which did find and repair errors, but it had no effect on the overall problem.

Download settings are already on "Full", as those e-mails which do come in are complete.

Ramin,

I did do an Inbox Repair, as you suggest, but that made no difference.

Thanks.

Clear.

What if you export the pst and recreate the mail profile? (First without importing the pst)

In answer to Patrick, I had already tried that and it had made no difference.

In fact, I have now solved the problem as follows:

  • In Outlook 2010 / Account Settings / Advanced, I unticked "leave a copy on the server".
  • Closed Outlook.
  • Rebooted the machine.
  • Relaunched Outlook
  • Did a Send/Receive - all OK now ( except of course no copy of emails is being kept on the POP server)
  • Reinstated "keep copy of e-mails on the server for 14 days" - Still all OK, working fine.

So it looks like there was some sync error between Outlook and the POP server in terms of what had been downloaded, what was being kept on the POP server (for 14 days) and what should be deleted from the POP server.

In effect the above process has flushed the POP server and allowed POP download/keeping to work correctly again.

I hope others find this solution of help.

Thanks to contributors
