Outlook 2016 Conflict with VPN

Anonymous

I'm using Outlook 2016 on MacOS Sierra and connected to O365. When working in the office, everything is fine. When working at home, everything is great as long as I'm not using VPN to connect to the office. As soon as the VPN is connected (Pulse Secure), Outlook performance heads south. Every email action - composing, reading, moving from one box to another - results in the spinning beachball for a few seconds. All other applications work fine with the VPN enabled, except Outlook. Any suggestions on what to do to diagnose the issue? I've tried changing DNS settings but that had no impact. Unfortunately I need the VPN to access the corporate web site and other services so cannot just leave it turned off.

    Dear Friends,

    I have my personal account Office365, install Outlook 2016 in Mac OS Sierra and use a third part VPN provider.

    When I open Outlook with VPN connected, Outlook always launch a message box looking for my email password and don't stop showing that box message even when I introduced the right password. I must close Outlook, turn off VPN then start again Outlook and it works fine (not showing message box to introduce my email password).

    Some people in this Topic, talk about a bad VPN bandwidth. But when I use my VPN to connect many HD video Services I don't have any Problem so I think there isn't problem related with bandwidth.

    Could you suggest me a solution.

    Best regards

    Charles

    Something like that can allow you to skip the VPN/proxy setting for specific hosts:

    It sounds like there is limited bandwidth accessing the Exchange account from work when VPN is on. Alan suggested switching to a better VPN, but from what I understand of what you’re doing, that’s not an option for you.

    You might inquire with the people in charge of IT at work and ask them whether anything can be done to increase bandwidth.

    I also wonder whether you could use VPN rule to exclude the Exchange server one way or the other. In any case, only your IT folks could help you out on this.

    Hi GPMacUser,

    From your description, I have understood that you are encountering an issue that Outlook for Mac 2016 performs a little slow while connecting to VPN.

    Since it works fine without VPN connected, my understanding is that the VPN might affect it. Let explain more: When the network environment is good (network speed is high, or bandwidth is high), Outlook for Mac 2016 should work better than that is connected in a bad network environment. As far as I know, VPN should reduce the network connection speed no matter whether the VPN’s bandwidth is high or slow. I mean, connecting to a VPN, the network connection speed should be lower (or much lower when connected to a slow bandwidth VPN) than that not connecting to a VPN.  

    For your current situation, my suggestion is that you may change another VPN with a higher bandwidth since you need to connect to VPN to access office.

    Regards,

    Alan
