Hi, i have add-ins collection for Microsoft Outlook installed and the trial period has expired. the buy now button leads me to a page that says that the product does not exist on the page.

I would like to buy it so please tell me how to do so.



Hello Mike,

Thank you for your comment. Sorry, we no longer sell Add-ins Collection for Outlook as it was built using the previous generation of the Office extensibility technologies that are out of date. We are not planning to develop the add-in further, it will be an end-of-life product in 2023.

I wish I could assist you more.

Hi I have purchased and use the Outlook addin collection.
How to I switch to the Shared Template version?
With the Shared Template version, can I control which templates the team sees? So I can have private templates on my PC?

I've just uploaded the latest version for Word, and, like the previous versions, when I run Linkchecker the formatting in my Word document becomes altered - my original document has no header space but after running Linkchecker, I find some header space has been added. Is there any way around this as I'm finding it a problem when working with multiple template-based Word documents. Thank you.

I am trying to install ablebits on excel in Office 365. It was previousdly installed on this VM machine. The machine was updated and the ablebits went away. I went to control panel to remove the program, but it was not there. I checked COM Adddins and it was there but not checked. It said it had loaded incorrectly. I removed it from the addins.

From the install package I tried 1. I tried to install the program, but it states it is already installed. 2. I tried to repair the program and it says it is not installed. 3. I tried to remove the program and it says it is not installed.

Thanks in advance

I'm trying to install this for one of my users in Excel 2016 on a windows 10 laptop. The install goes through normally and when you click on the open excel at the end of the installer it opens and you can see the ablebits tab. However when you close excel and then launch excel from the excel shortcut the ablebits tab is no longer there. I saw the same issue when this user was on a windows 7 machine with excel 2010. I can see that ablebits is installed as it is present in the appdata local folder. The add-on does not show in the com addins or disabled add-ins. If you can tell me what file in the folder to user i can manually add it. Thanks for your help

I am installing the Outlook BCC 'outlook-addins-collection' file in a PC (Windows 10) with latest version of Outlook (16) 32bit. and it runs and says it installed successfully. However it does not show up on the Ribbon, plus it's not the com list or disabled list. So...where did it go? why won't it show? Please advise so we can make the purchase. Thank you.
