Does think-cell work with Microsoft 365 (Office 365) and Office 2016/2019 Click-to-Run?

think-cell supports Microsoft 365 (Office 365) with the fully installed desktop versions of the "Office apps" as well as Microsoft Office 2016/2019 Click-to-Run (C2R). These two editions are very similar on a technical level: Both use Microsoft's Click-to-Run installer and they receive updates through channels built into Office. Everything below regarding Microsoft 365 updates applies to Office 2016/2019 installations that receive updates in this way.

Open any Office application and go to File > Account. If Update Options is available, you receive updates through a built-in channel. Here you can also see the update channel through which you receive updates.

(Microsoft 365 Business Basic and Office 365 E1 only include web browser versions of Office, previously called "Office Online", and therefore cannot support Office COM Add-ins like think-cell).

Microsoft update channels

Microsoft offers various so-called update channels which deploy updates with varying frequency and delay. For update frequencies and additional channel information, please see Microsoft's Overview of update channels for Microsoft 365 Apps, the Office Insider program and Update history for Microsoft 365 Apps.

think-cell compatibility with Microsoft 365 updates

think-cell supports all update channels of Microsoft 365. We check for Microsoft updates to all channels every night, and if there is an update that conflicts with think-cell, we immediately start working on a corresponding think-cell update.

Here is an overview of the quality of service you can expect from think-cell when using each one of the channels:


Default in

think-cell quality of service

Semi-Annual Enterprise Channel

Microsoft 365 Enterprise (Office 365 ProPlus) for tenants created before June 9, 2020.

We initiate an automatic think-cell update before Microsoft's update, so if you did not explicitly disable think-cell's automatic updates (see 2.3 Automatic update), no outage of think-cell should occur.

Monthly Enterprise Channel


Current Channel

Microsoft 365 Business, Family, Personal. Microsoft 365 Enterprise for new tenants created on or after June 9, 2020.

Semi-Annual Enterprise Channel (Preview)


The think-cell update is available for download, but we do not always trigger a timely automatic update.

When a conflict occurs and you have error reporting enabled (see A.3.5 Error reporting), a web page with the update will open automatically.

If you have error reporting disabled and Request Support not redirected to your own IT, and you select Request Support in the error dialog, you will get an automatic email response even outside of our business hours referring you to the update download.

Current Channel (Preview)

Beta Channel

We make the think-cell update available as soon as possible after the Microsoft update, but outages may occur.

Once the update is ready, the distribution mechanism is the same as for Preview channels.
