VPN Makes Outlook Slow?

We are using Check Point Endpoint security. And a few of my users have reported problems with their outlook taking an extra 15 secound to load when trying to open up a new message or reply to one alreday in their inbox. It is also only when they are connected to the VPN (working remotely). I am trying to figure out what we can do to solve this issue for them. Also I would like to add that its only with a few of my users.  My Users that are having this issue are using Outlook 2016 (O365)

Re: VPN Makes Outlook Slow?

Usually slowness of specific activities over VPN points to an MTU or fragmentation issue.

Have you checked out the traffic to/from the client with tcpdump?

Re: VPN Makes Outlook Slow?

Sorry for the delay with getting back to you, we don't have an MTU issue or a fragmentation issue, we have verified. Are there any other reasons why we could be having this isse?

Thank you for your time.

Respectfully,

Austin

I would open a case with the TAC so we can investigate the issue.
