Outlook and M365 - Slowness and poor performance loading profiles, and navigating app

[_techie_]

Hi.

 

We have had several (but not everyone) reporting that outlook is performing slowly.

This seems to be affecting users more with outlook in non-cached mode, but I have had users on the same laptop/workstation on InTune reporting the same issue.

I experienced the same issue myself approx 45 mins ago, but had to close Access down in order to delete my OST file....

Once done, and re-created my profile, everything is now working as expected.

 

We are a smoothwall school btw, and apparently not the only one having problems!

 

Anyone else?

We are seeing this too - yesterday and today

 

We are running Sophos XG Firewall and Sophos Endpoint antivirus

 

Haven't worked closely with the issue so don't know a great deal of detail on what has been tried so far

Just a thought, are you a Senso school? I believe the update was causing issues with Outlook performance as well?

Yes, disabling the Senso service improves matters instantly!

I will try the fix on one machine EDIT - their powershell command seems to fix it.

We are waiting however - Senso need to fix their stuff
