None beyond the role
Owner and Company admin open Company admin → Company → Settings → Files & retention, change the settings and select Save.
Keep messages and files
Under Message and media retention, choose Keep forever, Delete after 30 days, Delete after 90 days or Delete after 365 days. Encrypted messages and file blobs are removed after this period. Contents are never read.
The period counts from when a message was sent. Deleted messages and files cannot be brought back, so tell your team before you shorten it.
Upload size
Max file size (MB): from 1 to 50 MB per file. Larger files are refused when someone tries to send them.
Blocked file types
Under Blocked file extensions, enter one extension per line, for example exe, bat and ps1. Original filename is checked. Files stay encrypted; this is not content scanning.
Meeting recordings have their own retention. See Meeting settings: microphone filter, recordings and size.
