Restore an archived channel. Unarchiving restores the ability for users to send messages and edit the channel. Channels are archived via the channel: archive method.
Unarchiving is an asynchronous operation; a channel is unarchived when the asynchronous unarchiving operation completes successfully, which might occur after this method responds.
Note: An archived channel that belongs to an archived team can't be unarchived. Unarchive the team before you unarchive the channel; otherwise, the request fails.

If unarchiving is started successfully, this method returns a 202 Accepted response code. The response contains a Location header that specifies the location of the teamsAsyncOperation that was created to handle the unarchiving of the channel in a team. Check the status of the unarchiving operation by making a GET request to this location.
Examples
Example 1: Unarchive a channel
The following example shows a request to unarchive a channel.
POST https://graph.microsoft.com/v1.0/teams/16dc05c0-2259-4540-a970-3580ff459721/channels/19:[email protected]/unarchive
// Code snippets are only available for the latest version. Current version is 5.x
// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
await graphClient.Teams["{team-id}"].Channels["{channel-id}"].Unarchive.PostAsync();
// Code snippets are only available for the latest major version. Current major version is $v1.*
// Dependencies
import (
"context"
msgraphsdk "github.com/microsoftgraph/msgraph-sdk-go"
//other-imports
)
// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=go
graphClient.Teams().ByTeamId("team-id").Channels().ByChannelId("channel-id").Unarchive().Post(context.Background(), nil)
// Code snippets are only available for the latest version. Current version is 6.x
GraphServiceClient graphClient = new GraphServiceClient(requestAdapter);
graphClient.teams().byTeamId("{team-id}").channels().byChannelId("{channel-id}").unarchive().post();
<?php
use Microsoft\Graph\GraphServiceClient;
$graphServiceClient = new GraphServiceClient($tokenRequestContext, $scopes);
$graphServiceClient->teams()->byTeamId('team-id')->channels()->byChannelId('channel-id')->unarchive()->post()->wait();
# Code snippets are only available for the latest version. Current version is 1.x
from msgraph import GraphServiceClient
# To initialize your graph_client, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=python
await graph_client.teams.by_team_id('team-id').channels.by_channel_id('channel-id').unarchive.post()
Example 2: Unarchive a channel when the team is archived
The following example shows a request to unarchive a channel that fails because the team is archived; the team must be active to archive or unarchive a channel.
POST https://graph.microsoft.com/v1.0/teams/16dc05c0-2259-4540-a970-3580ff459721/channels/19:[email protected]/unarchive
// Code snippets are only available for the latest version. Current version is 5.x
// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
await graphClient.Teams["{team-id}"].Channels["{channel-id}"].Unarchive.PostAsync();
// Code snippets are only available for the latest major version. Current major version is $v1.*
// Dependencies
import (
"context"
msgraphsdk "github.com/microsoftgraph/msgraph-sdk-go"
//other-imports
)
// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=go
graphClient.Teams().ByTeamId("team-id").Channels().ByChannelId("channel-id").Unarchive().Post(context.Background(), nil)
// Code snippets are only available for the latest version. Current version is 6.x
GraphServiceClient graphClient = new GraphServiceClient(requestAdapter);
graphClient.teams().byTeamId("{team-id}").channels().byChannelId("{channel-id}").unarchive().post();
<?php
use Microsoft\Graph\GraphServiceClient;
$graphServiceClient = new GraphServiceClient($tokenRequestContext, $scopes);
$graphServiceClient->teams()->byTeamId('team-id')->channels()->byChannelId('channel-id')->unarchive()->post()->wait();
# Code snippets are only available for the latest version. Current version is 1.x
from msgraph import GraphServiceClient
# To initialize your graph_client, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=python
await graph_client.teams.by_team_id('team-id').channels.by_channel_id('channel-id').unarchive.post()
