Is it safe to add an exception to thunderbird folder?

I use Thunderbird for my email. For the past few weeks I've been getting the "Messages could not be filtered to folder ... because adding a message to it failed. Verify that the folder is displaying properly or try to repair it from the folder properties." error message with the unsorted messages being delivered to my inbox. This doesn't affect all the messages, It only effects messages that I have set up in my filter to go to a specific folder, trash or junk. This seems to be a bug with Thunderbird for quite awhile.

I begun using the 'Repair' function in the 'Properties' drop-down menu and even tried creating a new filter which may have worked on a few messages but it failed to fix the issue permanently. Once I click OK the message goes into my inbox. Once in my inbox if I click "Filter Messages in Folder", all the messages then go to the proper folders. 

Thunderbird told me to add an exception to my Thunderbird profile folder, as my anti virus is scanning the file the mail for that folder is stored in. They recommended I add an exception to my anti virus product for the folder where the Thunderbird profile folders are stored.

So.... if I add the exception, is that a good idea?  Doesn't that kill any virus protection for viruses that might come into my email?  I am confused as to what I should do safely.

thanks for any help!

Grafiti4u Thunderbirds built-in filters should provide you with default protection for spam and your rules are applicable from those settings. However!! Adding an exception to Norton will cause Norton to no longer scan those messages, all other Norton protections will remain intact. Are you on version 52.3.0 ? Thanks.

Re: Is it safe to add an exception to thunderbird folder?

Yes I am using 52.3.0.  I was afraid of not being protected, I didn't like Mozzilla's solution because of it. It looks like this bug goes back to 2014! I just don't know why it was fine until a few weeks ago, and now even with the upgrade it continues.   Its a pain as I will get over 100 emails in 2 days, and have to sit there and click ok each time the error message pops up - a real pain. Well, I hate to, but I might have to look at another email product.  Thanks!

Is Thunderbird giving you the error or Norton? Just a bit confused about which lol.

Thunderbird gives me the error, but thunderbird said it was my virus software that was making it pull the error.

Try turning off Norton Email Protection and Antispam Protection (you can stop the Norton alerts this will cause by going to Norton's Advanced screen under the Security tab and hovering your mouse pointer over "Email Protection" and clicking "Ignore").  If the problem persists, it is a TB issue.  If that solves the problem, you can leave those Norton protections disabled.  Thunderbird has an excellent antispam filter itself, and email virus scanning is not necessary because any threat contained in an email attachment will be caught by Norton Auto-Protect on access anyway.  Excluding your TB profile from scans will likewise not lessen your protection.  It is often recommended to exclude your Inbox and other important folders from scans anyway to prevent possible corruption by antivirus products.  See the following for more discussion:

Re: Is it safe to add an exception to thunderbird folder?

Thunderbird email databases (each folder is one) has a hard limit on total file size (~4GB). If you have lots of email in a folder and you delete most of them and add more you may hit that limit even if the files you have left are not huge.

If you have never hit the limit compacting the folder will get rid of this wasted space (used space will be almost equal to folder/database size afterwards).

If you HAVE hit the size limit then compacting the folder could cause you to loose all the messages in that folder (due to corruption).

Sounds like the folder Norton is trying to move messages to may be corrupt, you might want to check the sizes of your folder-databases.

@Grafiti4u Following up on the thread to see how you made out.

Re: Is it safe to add an exception to thunderbird folder?

Well, I decided I didn't want to add an exception, there had to be a better - safer way.  I found a solution where I went in and pretty much had to delete my inbox and have Thunderbird rebuild it again.  That seemed to do the trick.  So password_password above may have been right.  There must have been something corrupted in that file.  Once I did that, I didn't get anymore messages and I also didn't have to compromise my Norton security.  Thanks all!

Double check the sizes of your mailboxes (including the deleted one if you still have that info). You will want to keep an eye on mailbox sizes to avoid corruption. I'd be curious to know the approximate size of any mailboxes you are / are not having trouble with.
