I've definitely noticed the increased amount of time it takes to open Outlook, but apart from that I don't have any performance related issues. Are you running in cached mode and how big is the OST file? Did you try running Outlook in safe mode? You can also try the SaRA tool and see if it detects anything: https://diagnostics.outlook.com/

I tried running SARA, but when I get to the point that I have to enter my email and password, it keeps asking for my password over and over again, even though I know that the password I'm entering is correct. I tried turning off cached mode, but when I restarted outlook, startup time was easily 4x as long, and everything lagged, so I reverted back to cached mode. My OST is only 65MB. I have run the program in safe mode, and it stops the issue from happening until I open Outlook normally.

    I'm having this problem too. While I'm waiting for the support app to load I get the sign in over and over  - despite changing my password because the program told me I had it wrong. Did you find a solution? Cheers. Elle October 2018

        If it works fine in Safe mode, it's most likely some of the add-ins, although I don't see any suspicious in the list you provided. Double-check again and start toggling them off one by one just to see whether it will affect the issue. Apart from that, I'd suggest you temporary disable any AV and other types of scanning software, as they are known offenders.
