In Microsoft Teams, deleted channels remain visible in the "Deleted" tab for a specific period due to the platform's design. Here's why:
Retention Period: Deleted channels are retained for 21 days to allow for recovery if needed. After this period, the channel's content is permanently deleted, but the channel name may still appear in the "Deleted" tab.
Design Behavior: Even after the retention period, the channel might still be listed in the "Deleted" tab. This is a known behavior in Teams and doesn't necessarily mean the channel's data is still accessible.
Cache Issues: Sometimes, the Teams client may cache old data, causing deleted channels to appear. Clearing the Teams cache or reinstalling the app can help resolve this.
