Avast Free Breaks Outlook 2010

If so, it should not work when mail shield is turned off … or?

maybe this is worth a try Avast 2015: Using the Avast Support Tool https://www.avast.com/en-eu/faq.php?article=AVKB33#artTitle

Micheal529, as far as I know my ISP has not changed anything. Even if they did, it would be a great coincidence if they made a change at the same time as I upgraded Avast. It also would not explain why email works when email scanner is disabled and I can turn this feature on and off.

I was on my laptop last night and noticed that, surprisingly, my Avast on my laptop is also upgraded to Avast 2015. I have to check that it is version 2218. However, Avast 2015 is working okay on my laptop with Outlook 2010. The only difference is that my laptop is running Windows 8.1 Pro 64 bit and my desktop is running Windows 7 Pro 64 bit. I will investigate more later and verify that my laptop is running 64 bit Outlook 2010 and version 2218 of Avast.

Thanks Michael529 for the post providing evidence that this version of Avast will work with MS Outlook2010 on a WIN7 OS platform. Question: I’m assuming you are not using a Microsoft Exchange Server account but instead are using only POP3 and/or IMAP and/or Gmail.com and/or Outlook.com (formerly Hotmail) etc accounts which I understand is the case with richard244, right?

I’m running POP access to a range of accounts provided by variants of Yahoo mail; (these) Yahoo (now) expect to connect using SSL.

My version of Avast on my laptop is 10.0.2208.712 so while it is Avast Free 2015, it is not the same version as on ly desktop. The Outlook version is Outlook 2010 64 bit on both systems, however my desktop is windows 7 and my notebook is Windows 8.1. I don’t really think this tells us anything. While Avast on the laptop tells me there is a new version available,I am not going to update the software. Both systems are configured the same for Outlook and Avast.

I think you meant to say your Windows 8.1 laptop is Avast version 2015.10.0.2208 (which for you works with MS Outlook2010), which is 3 versions older than the Avast version (2015.10.2.2218) you have on your desktop under Windows 7 (that for you does not work with MS Outlook2010). Click HERE for Avast versions release history (or do you have a 2015 subversion on your laptop not listed on the Avast website?).

lakrsrool, yes, that’s what I meant. The laptop version is 2015.10.0.2208 I got the version number from MS Process Explorer and it showed the version with “712” tacked on to the end.

Is there a location to find older Avast versions for download?

I’m not aware of an official Avast download site that is available (maybe someone else knows) for older versions. Also as you know it’s very unpopular on this board to consider using older Avast versions (as you might have figured out) and of course I’m certain you are fully aware of what perceived risks there might be in regards to what many will tell you involves levels of reduced security so I don’t need to remind you of this factor. (I’m including all of this not only to serve as a disclaimer but more so for the sake of the critics on this board that would suggest in no uncertain terms that doing this is ill-advised ;))

So with that out of the way I can’t vouch for these download sites but here are a couple that from what I know are reasonably well regarded (I’ve point both to Avast):

  1. filehorse.com

  2. filehippo.com

I always get grief from some of the uber-Avast-evangelists on this board when I do this but the way I see it we should be free to do whatever we want even if what that might be happens to be at odds with the opinions of others.

I am running my Outlook 2010 with Avast 2014 installed and email scanner activated. This older version of Avast does not interfere with Outlook send and receive functions. I tried Avast 2015 versions 10.2.2218, 10.2.2215, 10.0,2208, 10.0.2206, and finally resorted to Avast 2014 version 9.0.2021 before I found a program that would allow Outlook 2010 to send and receive emails while the email scanner was activated.

If this is not an Avast software problem, please explain to me how I may be wrong on this issue. I don’t know if it effects every Outlook user or what causes it, but Avast 2015 broke Outlook 2010 on my system and Avast 2014 removes the problem.

lakrsrool, thanks for the links filehorse.com was good for all versions. However, filehippo.com downloaded Avast 2015 version 10.2.2218 regardless of which link for older versions I clicked on.

That’s interesting because it happens that what you are using is exactly what I am using, that is I’m using Avast 2014.9.0.2021 (the last release for Avast 2014) which is what works with MS Outlook 2010 for me as well.

I frankly have no idea why in some cases users can use versions of 2015 successfully with MS Outlook 2010 but in the case of myself and now as you’ve pointed out you as well the only way to get MS Outlook 2010 to work with Avast is to use the last release of Avast 2014.

Of course as I’ve said in the beginning there are a few reasons why I’ve stayed with Avast 2014 and this is one of these reasons because as I’ve said scanning emails is a relatively important security aspect of any AV program and whatever loss of security there might be doing this does not trump the scanning of emails which for me is critical because not getting emails scanned either arriving or reading them is obviously not a good idea at all hence turning off the Email Shield scanner was simply not an appropriate answer as was of course understandably the case with you as well.

Your welcome for the links and thanks for the “heads up” regarding filehippo (there is another site called I think “oldapps.com” but I’ve found that site to at times be unreliable as well).

Considering the fact that nobody has at this stage gotten back to you with any helpful solutions I’m happy to know that at least you can now have your emails scanned by Avast. Of course if the issue is ever addressed at some point you can always go back to Avast2015 at that time if you wish but in my view you’ve done what needs to be done to get the security you need regarding emails at this time.

It looks like I’ll drop my Avast Anti-Virus from my 4 machines and my clients machines. They forced an upgrade on me. When I sat down in front of my machine on which I had the Outlook 2010 problems, it was asking to reboot to complete an upgrade to Avast 2015 version 10.2.2218. I did the reboot and surprisingly my Outlook 2010 still works. I simply find the forced upgrade unacceptable. A company does not have the right to force there upgrades or configuration changes on me. This is very simply intolerable. What would they have to say if the upgrade broke Outlook 2010 on me. I can’t trust Avast. Goodbye.

A company does not have the right to force there upgrades
They sure do and you agreed to it when you installed avast.

Choose your language and submit your problem directly to Avast.

If that’s the case, then it’s a sad state of affairs for Avast that they will upgrade my software to a version that has been shown to cause me problems without my permission. I installed every Avast 2015 version Avast has releasesed and they all had the same problem with Outlook 2010 until I went back to the earlier version of Avast 2014 where outlook finally worked. Avast circumvented all of my efforts to use their product.

As I said, you did gave avast permission.

There are differences between avast 2014 and 2015.
Not only when it comes to handling/scanning the mail, but other things as well.

I have helped many peoples with the “mail problem”, and not only with Outlook.
All had their mail client setup incorrectly.

Have you checked if the root certificate was correctly added to the trusted certificate store. ?

Yes.
