Users are confronting an issue with the Dynamics365 Outlook PlugIn. When using they regularly receive an "Error loading Control" error. We are also see an increased time when trying to authenticate.  See screen shots below.

    RE: Dynamics365 Outlook PlugIn Error loading Control and authentication delays

    Hi Lisa MB. Dozens of associates at my company get this exact same error and I have the issue frequently on my own machine. We started getting it after we went from Office 365 Semi Annual Enterprise channel version 1908, Build 11929.xxxxx to version 2002 and version 12527.xxxxx. I've done a LOT of troubleshooting, and found that the error pops up after one successful load of the dashboard and whenever the Outlook plugin/app tries to reload the cached file DashboardCore[1].js in %localappdata%\Microsoft\Windows\INetCache\Low\IE. 

    If I close Outlook completely and reopen it, the first e-mail I track always seems to load the dashboard fine without any errors, but if I take that same e-mail or switch to another e-mail and reload the plugin or close the e-mail, reopen and attempt to track again, I will always get this error until I either clear the cache, manually find all dashboardcore[1].js files in the cache and delete those, or I wait until I have to start a fresh re-authentication session with the CRM plugin in which case it stops trying to load the files stored in the InetCache. In some cases, I noticed that once you get the error 10x in a row, it will force or start a new session, but then the cycle repeats.

    It's extremely annoying, and the issue seems like it is inconsistent or random, but is actually very consistent once you see the pattern. I'm finally glad to find someone else is out there that has seen something similar. I even created a batch file with the following commands and this hints that the errors are within the downloaded .js (javascript) files in the INetcache folder. I'm really hoping someone from Microsoft will see this and respond. I'm experimenting with reloading different versions of Office, but I think it would be far better if the error could be isolated and fixed in a later version of the plugin.

    If you create a batch file with the following lines and you get the error message, running this batch file will "fix" the issue temporarily, but it will just come right back.


    cd %USERPROFILE%\AppData\Local\Microsoft\Windows\INetCache
    del /s /q DashboardCore[1].js
    pause
