Outlook opens painfully slow with Sophos Central and Intecept X

We recently switched from on-prem Sophos to Sophos Central with Intercept X and EDR.

Just started happening with the past couple of days, but when a user opens Outlook it takes forever to load.  Anybody have any ideas?

I came across this Allow computers to send data on suspicious files, network events, and admin tool activity to Sophos Central, but it is hardly a solution; it is turning off the very thing we paid money to have.


  • Hi April, 


       Can you tell me if this only effects a single OS and particular version of Outlook? How many users in total are effected?

    A valid step would be to try applying the Intercept X hotfix, which is basically a beta patch for the fixes planned for our next release: https://community.sophos.com/kb/en-us/133140

    Let me know what result you get.


    Thank you,

    FYI: This may be an Outlook issue, I would try either an repair/reinstall of Outlook first.
