Cannot backup Outlook.pst - API call error, Access is denied. 80070005

Hi family.

I have two backup programs that I use to backup various files. My problem is with Outlook.pst. This is a new issue for me, it has never happened before.

When trying to backup Outlook.pst with alwaysync I am now getting error API call error, Access is denied. 80070005
I am getting the same error now with my Outlook 2016 backup plugin , the plugin works but hits the denied error. This tells me it is something other than the software or the plugin. I don't know if it is maybe a win defender issue or what it may be, I am stumped.
I have checked permissions for both the outlook.pst file and the default folder it sits in documents/outlook files/
I have full permissions with both.

Anyone have any idea why this may have all of a sudden started? I'd be ever so grateful.

Win 10 64 up to date/Office 2016 up to date.

cheers :)

When Outlook is running it locks its .pst file, so it cannot be accessed.But if you shut down Outlook the .pst file will be unlocked, and it will be accessible for backup.
In the past were you backing up with Outlook running? Or with Outlook not running?

Hi mate. Outlook is never running. This happens when I just open windows and my backups start. I have also checked what is running at other times that this happens, unfortunatly that isn't the issue, I wish it was that simple.

Cheers for bringing that up though

Thanks man, I've never heard of Lock Hunter, when I wake up after the famous 3 double shot espresso's I have to have to operate in the morning, I'll boot up the PC and give it a go. Thanks!!

I tried that Lock Hunter, it says its not locked by anything. Still getting following error in allwaysync and still cant use backup plugin for outlook. Really weird

Code:

API call error, Access is denied. (80070005), filename: Error while copying "E:\Documents\Outlook Files\Outlook.pst" to "E:\_Backup\OUTLOOK 2016 PST BACKUP\Outlook.pst", fs::copyitem::access_denied

Now a New one

Code:

\Outlook.pst", fs::copyitem::DaCreateFolderEx

Everything else backs up fine, tens of thousands of files.
All my software and OS are legitimately owned.

Disabling Kaspersky Internet Security has no affect.

Quite bizarre.

I opened start menu, asked Outlook 2016 icon to run program as administrator.
Opened Outlook 2016 as Admin
Closed Outlook 2016 / Backup plugin started and ran without error
Opened my Allwaysync program and asked it to manually start backup of of Outlook 2016 (without outlook running of course) Backup completed without issue.

So running Outlook 2016 as admin and closing outlook, seems to allow the apps to backup.
I tried running outlook again without admin privileges and again backups failed

Freaking weird in my opinion.

Just a thought but do you have auto archive enabled in Outlook?

Hi there!

Never, I always disable archiving all together. I don't see the point in it. I am pretty anal when it comes to outlook due to the important messages and private info I have to deal with so I deal with each email as it arrives. I either save it to a specified folder that I always have access to or I delete it.

Thanks for taking an interest though.
