Members can send unlimited messages in Slack, but only the most recent 10,000 can be searched and viewed in your workspace. Keep in mind that deleted messages don't count towards this limit.
If your workspace exceeds the message visibility limit, that’s okay. Members can continue to send messages, but older messages will be archived. If you upgrade your workspace to a paid subscription, all archived messages will become available again.
What counts as a message
Anything typed into the message field and sent to a channel or direct message counts as a message. A one-word message (or even a single emoji) is counted the same as a message with 500 words and multiple paragraphs.
Links, snippets, posts, uploaded files, replies in a thread, messages in archived channels and messages from bot users all count towards your workspace’s total number of sent messages.
File storage limit
On Slack's free version, workspaces have up to 5GB of file storage available. Anything uploaded to a channel or a direct message (e.g., PDFs, documents, images, screenshots, audio and video files) counts towardsthis limit.
If your workspace reaches the limit, members can continue to upload files, but Slack will start archiving the oldest files to make room for new ones. Members won’t be able to view archived files in channels, direct messages or search results.
