OWA Remote access - 404 - File or directory not found.

We have a single sbs2011 server which we are accessing for this particular user, via OWA.

All has been working fine, but since a recent Adobe Flash update (this of course may be nothing to do with the problem), whenever we run OWA using Internet Explorer, we get :-

404 - File or directory not found.

The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

Google Chrome works just fine, and we can also use Internet Explorer on various other devices, and all work fine.

The problem must be related to this Windows V7 Home / Internet Explorer V11 laptop, but I just cannot find the solution.

The OWA screen starts up OK, we can then input the username and password, we then get a flash of the correct OWA page showing check e-mail etc, but we very quickly then get the 404 - File or directory not found.

The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable, error page.

Other usernames and passwords also produce this error on this particular instance of IE.

Can anyone advise what we can do to resolve it??

Many thanks.

I'd check for malware first, to be completely honest. Run a scan. It sounds like something is trying to redirect the browser once credentials are added.

I could be wide of the mark here, but this sort of behavior would make me very suspicious.

Nothing concrete really. Is the certificate up to date?

The fact you see the page then get redirected is the odd part. Since IE updated, you could try lowering the security level, adding the site to trusted sites and/or checking pop up blocker. I don't think that it could choose to open anything in the main window instead of displaying a pop up, but might be worth just making sure that pop ups are enabled on that page.

Don't really have anything better off the top of my head. The fact it works in Chrome too makes this a real head scratcher!

thanks for trying to help.

I have added the URL to the trusted list, but it's not made any difference.

the Ssl for the server is due for renewal, but not expired yet, but as it works with chrome and other ie devices, i don't think this is the root cause.

anyone else got any advice?

regards

sorted!

not sure the reasons behind this, but when we run it in compatibility mode, it works just fine.

been working ok for a couple of years now without, so why this would suddenly be required is unknown to me,

the main thing is that it is now working, so many thanks for your assistance.
