2. General Issues and Resolution or Workaround 

2.1. ShareSimple is disabled on the Desktop Client because of another Plugin 

In Desktop Client of outlook ShareSimple is shown as grayed out if the client has another plugins / COM Add-In installed in outlook. Not all plugins are doing the same, however, there are few plugins that are disabling the web add-in. Disabling those COM add-ins enables ShareSimple and works okay. 

Here are the examples of a few Plug-in/COM Add-In:

  • Advosys
  • Swyx Plugin
  • Avast antivirus

It is not always for all Outlook clients.

It is an open issue for Microsoft and lots of other companies are also facing similar problems. By trial and error method few steps are given below that may resolve the issue.

2.4. I cannot install ShareSimple from the admin center – on Prem Exchange

You are an admin user trying to install the add-in for the total organization from the admin center as a tenant admin. The installation was successful. However, the end-user cannot see the ShareSimple icon in their outlook as well as owa version.

Before investigating further please make sure the tenant is ready for centralized deployment or not- Please follow the step described in the document to check if the tenant is ready for centralized deployment It needs an admin user to check the tenant is ready or not.

2.5. How to install an Add-In from Admin Center 

i) Log in at and go to the Microsoft 365 admin center by clicking Admin:

ii) Click Show all on the left navigation panel:

iii) Under Settings, click Integrated apps:

iii) Click Add-ins:

iv) Click deploy Add-ins:

v) Click next:

vi) Choose Deploy from the Store:

vii) Use the search box to find ShareSimple in the Add-in store and click Add: 

viii) On the Configure add-in page, decide who will get ShareSimple. You can select Everyone, Specific users/groups. Use the Search box to find specific user accounts or groups. Then, click the Deploy button:

Assign users options:

  • Everyone: This option assigns the add-in to every user in the tenant. Use this option sparingly and only for add-ins that are truly universal to your organization. Make sure the number of users you add/remove matches your ShareSimple subscription.
  • Specific users: You can deploy ShareSimple for specific users. Make sure the number of users you add/remove matches your ShareSimple subscription.
  • Groups: If you assign an add-in to a group, all users added to that group will automatically be assigned the add-in. When a user is removed from a group, the user automatically loses access. 
  • Just me: If you assign an add-in to just yourself, this assigns the add-in to only your account. This is ideal if you wish to test out the add-in first.
  • Pick the option that is right for your organization. 

    Microsoft recommends assigning Add-ins to groups. As an admin, you may find it easier to manage add-ins using groups and add or remove users from groups rather than having to change the users assigned. 

    In some situations, you may want to restrict access to a very small set of users by choosing specific users. As a result, you will need to manage the assigned users manually.

    ix) The add-in has been deployed. You can follow the on-page instructions to test that the add-in has deployed successfully.

    Note: Users may need to relaunch Office to see the add-in icon appear on the ribbon of the app. Outlook add-ins can take up to 12 hours to appear on users' ribbons.

    x) You will get an email you can use to announce the add-in to your users, if you like.  Click Close to finish.

    3. I am using a package of Office 365. However, I am not able to install the ShareSimple

    Installing ShareSimple requires a valid license. For a customer, it can be for different reasons and the Microsoft Product Package has so many variations it is difficult to say which license is valid for running an Outlook Add-In. To identify if an email can install the ShareSimple or not you can ask the following questions to your client:

    • What Office 365 license the client is using.
    • What is the version of Outlook? (A lower version of Outlook 2013 with updates does not support Add-in and for Mac minimum Outlook 2016)
    • is providing Office 365 Plus which is comparable to Office 365 Business. I think the license does not include installing Add-in. Please make sure if your client has a proper license by asking support of
    • Check with the Client if they get the Store Icon on their toolbar.
    • If the store icon is present, then if it is possible to install any other Add-in.
    • If they can log in using, they can try to install the add-in there.

    Supported Licenses for outlook add-in:

    • Office 365 ProPlus
    • Office 365 E1 License
    • Office 365 E3 License
    • Office 365 E5 License
    • Exchange Online

    Check the Graph API explorer to make sure the email is applicable to use ShareSimple or not:

    4. I am unable to use the service, though the login is successful – I have Unilogin or SSO with my organizational id and Office 365

    If any customer has a “Unilogin” setup for their Office365 tenant, then it is required to identify which is the actual “mailbox” address of the user-defined for the tenant. We can use the link below to identify the information that is provided by Microsoft Graph API:

    The user needs to sign it with his/her user credential and get the response back from the API. By looking at that we can determine which is the mailbox address for that particular user.

    5. If the user has two emails together and associated which email to use in the ShareSimple from Admin

    For Unilogin or similar setup, users may have two emails – one is for their organization email which is used for sending and receiving mails and the other one is the actual Office 365 email which is used internally to authenticate with Office365.

    In this scenario if you want to add any user from the admin site then use the email which is used in his Outlook – you can see that left side of the outlook desktop or outlook on the web.
