More than 10 million people rely on Groups in Outlook every month to work together and get things done. Groups is proving useful to our customers. And for that, we couldn’t be more thankful. Groups in Outlook offers huge improvements over traditional distribution lists, with a shared space for group conversations, calendars, files and notebooks, the convenience of self-service membership and much more.
Today, we’re pleased to announce Groups is now rolling out to Outlook for Mac, iOS and Android. Groups is already available in Outlook for Windows and on the web—so now you can access your group conversations and content no matter which platform you use.
Expand your Outlook. We've developed a suite of premium Outlook features for people with advanced email and calendar needs. An Office 365 subscription offers an ad-free interface, custom domains, enhanced security options, the full desktop version of Office, and 1 TB of cloud storage.
With these updates, you can:
There is more to come as we continue to work on making Groups better in response to your input, so stay tuned.
In addition to bringing groups to more Outlook apps, we’ve released several new features for Groups in Outlook on other platforms, too.
Give guest access—Last fall, we updated Outlook on the web to give you the ability to set up guest access for people outside your organization, set group classification as defined by Office 365 admins, and view usage guidelines. Now, these same capabilities are available in Outlook for Windows.
Invite people to join—One of our most requested improvements was an easier way to invite multiple people to join a group. We’ve released the Invite to join feature to Outlook on the web, which lets you create invitation links and share them with others via email or other channels, giving them a quick way to join the group.
Multi-delete conversations—Group owners can now multi-select conversations and delete them from the group conversations space in Outlook for Windows.
Send email as a group—Office 365 admins can grant send-as and send-on-behalf-of permissions to members of a group using the Exchange admin center. Group members who have these permissions can then send emails as the group, or on behalf of the group, from Outlook for Windows and Outlook on the web.
We’re always listening to your feedback as we deliver new Groups capabilities to Outlook. Here are a few of your key requests we are going to tackle next:

I’m having a problem with Outlook sending multiple copies of some emails – usually those with attachments.
It doesn’t happen with every email with attachments, just occasionally. It will send it 20-30 times but keeps the email in my Outbox saying that it hasn’t been sent (although sometimes it says it’s been sent but stays in the Outbox).
How can I solve this and make sure Outlook only sends out one copy again?
This often happens when you are using a virus scanner that integrates with Outlook or when your Send/Receive interval is set to a very short time.
In some cases, especially when you have a slow connection to your mail host, extending the mail server time-out may solve it as well.
Resetting your modem, router, hub, WiFi Access Point and/or other network appliances may sometimes already be the answer too even when all other network connections seem OK.
When you have a virus scanner installed which integrates itself with Outlook, it will scan outgoing emails as well.
Throughout the years, virus scanners have proven over and over again to cause more issues than they claim to solve in Outlook.
It is really recommended to disable or uninstall your virus scanner’s Outlook integration capabilities. This will not put you at risk in any way. For steps on how to properly disable the integration, see the documentation for your virus scanner.
For more background information see “Duplicate E-mails” and “Disable virus scanner integration?“.
When your send/receive interval is set to a very short period (below 5 minutes) and your message takes a while to upload to the mail server, it could be that the next send/receive interval already started before the previous one completes.
This will then cause a backlog of Send/Receive tasks which still need to be completed. In the worst case scenario, it could be that the message still in the Outbox will get resubmitted for sending and thus create a duplicate.
You can open the Send/Receive Progress dialog to see if there is a backlog:
You should only see up to 2 tasks per mail account in this dialog. When an account is listed more than that, your send/receive interval is too short.
To change your Send/Receive interval go to:
The default value is 30 minutes. As mentioned before, don’t set it lower than 5 minutes. When you have 3 or more accounts configured, it is recommended not to set it lower than 10 minutes.
Checking for new emails too often could interfere with the sending process.
POP3 and IMAP accounts work with Server Timeouts. This basically tells Outlook when to consider a connection as “lost” when no server responds has been received after a configured amount of time.
By default, this is 1 minute. When you are on a slow or unreliable connection or a connection with a high latency (like mobile connections), then it could be that you reach this timeout. In that case, Outlook will resubmit any message in the Outbox upon the next Send/Receive interval.
When the message was actually already submitted to the mail server but the acknowledgement was not received before the timeout was reached, the message will be submitted again and thus create a duplicate as well.
Increasing the Server Timeout to 2 or 3 minutes may solve your issue. Directly setting it longer than 3 minutes is not recommended as it often means that the actual issue lies somewhere else.
Increase the Server Timeout when you have a slow or unreliable connection.
