Hello

After a few weeks of narrowing it down, reinstalling etc. I've determined that IMAP is terribly slow in Outlook 365/2019 with ESET Endpoint AV installed. Even with everything email related disabled in the policy etc. If I reinstall it, it does fine a day or two, then its back to dragging. Any suggestions on how to fix this?

Thanks

Thanks, I will try this for a few days and report back.

I contacted support a few days ago about this and basically couldn't duplicate the issue while we we're on the phone. But I can confirm on my Laptop/Desktop it's still an issue. But I will try this and report.

Thanks

@LesRMed thanks

Yes I keep thinking that. It worked fine for a couple years and all of a sudden my laptop started doing it. A month or so later the desktop. And I’ve had a couple customers with minor issues.

 

i can uninstall AV and Outlook runs fine, reinstall and then it may be good for a few days and right back to slow.

 

im getting real anxious now. Maybe I’ll reload a machine and go from there, but I do have a newer desktop it’s on rn. So idk. Probably something I’m overlooking or goofed up in my policy.

I'm not sure what else to do, aside from loading a machine fresh which I haven't had time to troubleshoot much further yet. I did add exclusions for the Office Directory and PST/OST files (all email security functions were previously disabled in the policy).

However I'm still convinced it's ESET somehow, I mean it only occurs when ESET is installed. I had to uninstall it to get my email, that's very inconvenient.

I'm determined to find out exactly whats going on just haven't had much time to work on it. I thought it might be an Outlook Addon I was using but I uninstalled it for about a week and it made no difference.

Side note: I'm using Linux Mail Security 4x on the IMAP server.

I'll post back any findings.

Thanks

Hello @rgoldman,

when it comes to exclusions for the Office Directory and PST/OST files my personal guess is that it won't help much.

In case it is ESET related I would say that it is either caused by the Outlook plugin or the IMAP(S) scanning.

Can you try how it behaves 

1. with the Outlook plugin disabled

2. with the IMAP(S) scanning disabled

If the issue persists, based on that we will know where to focus the further troubleshooting...

Peter

Hey @Peter Randziak

Thanks

Yes already tried that as I said before. Tech support and I disabled everything email related in the policy. They couldn't confirm the issue, but if I use it for more than a day or so it's really bad.

I don't think it's my machines. Desktop is Intel i9 CPU with SSD, Laptop is Intel i7 with SSD (my phone doesn't have this issue). The server is sitting right next to me, it's running Xeon with SSDs under light load.

But I can tell you if I uninstall ESET AV Outlook w/ IMAP is very responsive, where as it was taking 5-10 minutes (or more sometimes) to send a message or update a folder. Mailbox size is only about 2.5GB.
