I am currently working on a custom outlook addin generated with the yeoman generator. I have done this for word already and there I didn't have any problems. In Outlook it took quiet a while and a Microsoft 365 Subscription to load the addin but now it isn't visible in Outlook and I haven't found any kind of solution fitting my problem and situation.

I have already tryed sideloading it with the link provided in https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/sideload-outlook-add-ins-for-testing as well as sideloading it via code and npm. I also checked if the manifest is valid with the validation funktion included in the autogenerated template.

    If the issue persists, the add-in may have been disabled, please follow the link to turn it on and see if there is any difference.

    Hope it helps!

    @Joan Hua-MSFT thanks for the fast answer.

    I tried two different thinks to add the addin in my outlook. The first way was to use the way that is descripted in the picture you send. So to use the sideload-link in order to open the window to manage my add-ins and then add my custom add-in via the xml-upload. The second way was to use the command "npm start" in my coding enviroment to sideload the manifest via code. In both ways I was abled to see the add-in as "Installed" in the Add-in Tab, but the Content of the add-in is not there.

    One think to not ist, that I dont have a possibility to access the window to manage my add-ins outside the sideloading link. I thought that there should be a button to lead to this window like in Word or Excel, but I wasn't abled to find it in neather version of Outlook I used so far. Furthermore I wasn't abled to use your tipp regarding the "deaktivated add-in" because I didn't have a setting to manage my add-ins in the webversion.
