An error message appears in Ms. Outlook (We cannot render a new actionable message right now)

They claim it as a fix as of Jan 5 https://support.microsoft.com/en-gb/topic/error-when-opening-actionable-messages-be7b8154-f293-4784-a3d9-08bef7f4c36e

All prior bugs for this issue have been fixed. That said there is still a limit to how many actionable messages you can open before you see this message.

In Current Channel its now 10 actionable messages

In Monthly Enterprise Channel its 5 actionable messages

In SAC and later channels its 5 actionable messages

The limit of 10 will go to MEC soon and progress to SAC shortly thereafter.

In the meantime, if you get that message, close any prior Actionable Messages you have open to avoid seeing the error dialog. Long term Outlook will keep iterating to make the number higher as performance allows e.g. higher than 10.

Here is the Known Issue article we have explaining the current status, Error when opening Actionable Messages - Microsoft Support.

Hi all, today I got an error message when opening Ms. Outlook with the following error message (We cannot render a new actionable message right now. Please close an existing one in Microsoft Outlook and retry) As for what I have done =

*Update office version

*Re-install O365

but neither of those things solved the problem, really appreciate if anyone in this forum can give more advice.

(no problem sending messages via OWA)

I just received this alert for the first time on January 9th, 2023, was this ever solved by Microsoft?

Neither of the option helped :(

To get the fix you need to be on build 15128.36125 and higher. Since you are on MEC channel see if you can update to Version 2208 or higher. This page shows what builds and versions are at each channel, Update history for Microsoft 365 Apps (listed by date) - Office release notes | Microsoft Learn. MEC is at Version 2208 and higher. Try manually updating by clicking File, Office Account, Update Options, Update Now.
