Outlook 2016 Office 365 Exchange online glitchy and laggy RRS feed

  • Question

  • Ever since we migrated to Exchange Online/Office 365 Outlook is very glitchy/laggy sometimes. The Outlook window will stop responding and the program will glitch out, meaning you will see some parts of the program that are blank and some text menu items will be missing. Sometimes you will not be able to type in the body of the email. When that happens you can still navigate in outlook and save the email as a draft, but when you open the draft if you typed a bunch of random stuff while you couldn't type, the garbage you typed will be in the draft. The calendar will freeze, you can't click anything in the calendar, then you click the file tab and back and the calendar lets you navigate. There is a lot of delayed typing where the keyboard input lags 10 seconds behind. Outlook doesn't officially crash or go to not responding. The interface just becomes very glitchy and laggy.

    In general it just runs like crap sometimes. I've tried disabling graphics acceleration and that doesn't make any difference. Sometimes waiting or clicking around is enough to get it out of it's funk. We are in caching mode. This is all happening to me and a coworker. I'm sure others are experiencing this but not reporting it. I'm on the current update model and he's on the deferred update model. Both windows 10, we've replaced his laptop recently so it's a pretty fresh install. Repair and reinstall doesn't fix it.

    What gives? We don't use a lot of plugins except for Mimecast. It's like outlook is trying to contact the server and it gets stuck or there is a long delay that is visible in the UI. We have a fast dedicated fiber internet connection, so I don't think that's it. We have people that remote into Citrix and if the internet connection were a problem they would complain about it.

    Thanks,

    John

  • Hi John,

    What's the version of problematic Outlook clients? Do have any previous versions of Office installed on your computer?

    Are there any anti-virus software running on these computers? Please try temporarily turning off these problems to see the result.

    Regarding Outlook add-ins, normally, we could start Outlook in safe mode to test if the problem is related to any third party add-ins. To do this, please exit Outlook, press Win key + R to open the Run command, type outlook.exe /safe, press Enter.

    Have you tried creating a new profile to see if issue continues? To do this, please go to Control Pane > Mail > Show Profiles > Add.

    We could also use the Microsoft Office Configuration Analyzer Tool (OffCAT) to get a detailed report of your installed Office programs. It also highlights known problems that are found when OffCAT scans your computer. For more details, please refer to this link.

    Besides, in case this issue was caused by software conflicts, please try performing a clean boot in Windows to check the result.

    What's more, you could also refer to this article about performance issue with Outlook.

    Any updates, please feel free to post back.

    Regards,

    Perry
