    Ah ha!

    After a rather busy day I have finally managed to investigate this issue further.

    When using IE to browse and use login.microsoftonline.com it's painfully slow. Using Firefox or Chrome works a charm.

    So looking into the settings for IE, there is one for 'Check for server certificate revocation'. If enabled is what's killing the https connections. When this is disabled access to https sites goes through smoothly on IE.

    I'm tempted to just disable this via GPO and be done with it but I'd rather ask the Oracle aka Edugeekers about whether there's another way to fix this without compromising things.

    Thanks

    So what is Lightspeed doing to slow that down?

    Haven't a clue but when I sent the internet traffic from my PC via the old smart cache it works fine but Lightspeed at the moment aren't convinced that it's a Lightspeed issue.

    I have added my PC as an exclusion on the Lighyspeed box but the issue is still there.

    I will plug a laptop directly into the router tomorrow and see what that brings up!

    Does it work if you disable CRL checking but still go through the Lightspeed does it still happen?

    Likewise, having that enabled but not going through the Lightspeed what happens?

    Disabling this setting within IE makes iE behave normally.

    I will setup a laptop tomorrow that will go through to the we without going via the Lightspeed box and see what happens.

    Prior to having the Lightspeed box in place this wasn't an issue.

    I have just got my laptop accessing the internet directly through our firewall/router and there was no issue what so ever when having 'Check for server certificate revocation' enabled.

    When I set the laptop up to go back through the LS box with this IE setting in place then we get the issues with accessing https stuff again.

    I have fired this back over to Lightspeed so we shall see what they say.

    Very odd!

    bodminman,

    I did get a reply from Lightspeed which was no help what so ever as i am experiencing the same issues at out site;

    The connections to Office 365 appears to be to random external IP Addresses on Port 137 when I looked through your Web Activity Report yesterday, if the server was on site it could be added to the Rockets Internal Ignore list.
    - What a load of rubbish!

    Still awaiting for an educated answer

    So I assume connecting to Office 365 through Outlook operates normally? We're going live with Lightspeed soon so be interesting to see.

    At the moment I can't get my outlook to connect through to O365 although it has worked but it stopped earlier this week. I shall be tackling this tomorrow and I will let you know how I get on.

    Make sure you have P2P turned off on your Lightspeed box, I am now getting the following error when users try and access out o365 SharePoint;
    If you retry the SharePoint link again it allows you through.....

    I'm seeing that too actually if I use mail.ourdomain.com. If I go to the proper login page it works.

    Is lightspeed blocking access to the CRLs you need? That could slow things down as IE will look to see if the cert has been revoked and have to wait $timeout seconds to find out that it can't...would hope lightspeed have a CRL category you can allow?
