Microsoft Teams: Your message is too long. Please shorten it before sending

Published 16/06/2017 - 6 Comments



Microsoft Teams has a maximum message length, but I can’t work out the variable that set it off. At pure word count it appears to be ~2,400 words, but if you paste an IM chat from SfB with way less words all the line breaks/paragraphs seem to flag it too.#

I will see if I can find out the combination of factors that set it off.

Hi Tom,

Have you managed to control maximum messages lengths in Teams?

    Tom Arbuthnot - 13/10/2017 Reply

    I’m not sure what the limit is. What are you looking to achieve?

Did you finf a way to change the word count limit? and is it still 2400 as you mentioned above?

    Tom Arbuthnot - 09/02/2018 Reply

    No, no way to change that I am aware of.

What were you thinking when it was decided to have a word count in an area that you claim is for discussions?

We’re just transitioning over to Teams and away from email, but even the shortest of emails are too long for a comment in Teams. And as for your cheery note, “You’ll need to shorten your message to send it.” I say “No. I need to shorten the time I’m spending trying to figure out what you mean by what you say.” Don’t patronize me. Either tell me what the count is or don’t have a count at all. Better: “Your message must be less than 2,400 characters including spaces and punctuation.” Then, blast you, don’t make me copy the message to Word to get the count! Have the counter there for heavens sake.

What’s the point of teams if I can’t have a robust discussion of an issue? Why not just continue to use email where I can at least have a robust, timely (and time stamped) conversation on an issue? At this point I really don’t see the advantage of Teams.

    Thanks for sharing your POV. I guess by “you” you mean Microsoft, I don’t actually work for Microsoft :-). I suggest you share your opinion on their forum ( or user voice (

    From my personal POV, if a message is that long, it’s more of a document than a message, it might be better distributed as such. I find people rarely read long emails or messages end to end.
