  1. Implement Sender Rewriting Scheme (SRS) to Resolve Forwarding Issues

    Forwarding in SMTP is fundamentally flawed unless you implement SRS.

    http://www.openspf.org/SRS

    If you maintain the Return-Path of the originating message while forwarding you effectively spoof the originating domain.

    If you modify the Return-Path to be the address of the account that forwarded a message you break the Return-Path chain and delivery issues will result in the forwarded message Delivery Status Notification (DSN) being delivered to the forwarding user and not the original sender.

    SRS resolves this by modifying the Return-Path in a way that doesn't spoof the originating domain but still allows DSNs to be sent to the original sender.

    • Change Exchange Online recipient limit

      Need to change Exchange online Recipient Limits. The default value is 500 and can't be modified.
      In this case, users are able to send bulk\Spam messages by selecting entire global address list.

        Thank you for the feedback. Most of the comments here reflect a desire to be able to LOWER the recipient limit for a specific user. This is something we will consider as resources allow. We would be curious if this is driven more by account compromises or just user behavior (e.g., don’t have permissions to send to the DL, so the user just expands the DL)?

        For any comments regarding other issues with limits or throttling, please start NEW items and please be clear what the scenario is that you need to support and why. Limits are a necessary piece of any email service, but we don’t want them to be obtrusive and block valid business scenarios.

      • allow quarantined emails to be deleted from the quarantine list for clarity

        ability to delete emails in the quarantined queue that were reviewed and are irrelevant . this will make it easier to check the queue over time instead of waiting for the messages to expire.

            We should be able to see with subscription / product was assigned or removed to an office 365 Account. In the Actual audit log, there is only few information that is not relevant at all!

            • Improve message tracing in Exchange online

              We have had a lot of issues with spam, whether its cryptovirus emails getting through, or good emails getting improperly blocked. Because of this, we need good message tracing (to find the emails), which we do not feel we have with exchange online. We would like to make the following suggestions:

              1. Need to be able to trace further than 7 days back without a 4 hour wait per trace. Our previous message tracing system could go back the entire year nearly instantly, but we need at least 30 days without the 4 hour wait per trace. This was pitched…

                Thank you for taking the time to submit this feedback. Since there are multiple pieces and layers of feedback in this single post, it makes it more difficult than many to address. First, let us share a little about what we’ve been doing. Since this post was made, we have prioritized performance and reliability improvements for both Message Trace (inside 7 days) and Historical Search (typically outside of 7 days). We’ve added details to Message Trace that weren’t there before, decreasing the need to run Historical Searches inside of 7 days. For Historical Search, we have improved the results to be more clear for those who are not familiar with the Exchange Message Tracking log format. Additionally, while we get the total value of Message Trace, we’ve also prioritized reducing the constant need to search & destroy. We’ve made tremendous strides in effectiveness, even as the bad guys got more…

                • Ability to add company logo images globally to all user signatures

                  The ability to add a company logo or image to a signature as an admin globally for all users would be nice. Currently the suggested solution to append a disclaimer isn't ideal as it always posts the image to the very bottom of the email, not the signature. This doesn't work for a back and forth conversation thread since it starts stacking the image at the bottom.

                  • End User Spam Notifacation - Frequency

                    Currently we can only have 1 email sent per day notifying the user they have spam in quarantine.

                    The email is usually sent just after midnight so if the user does not check their quarantine it could be a full 24 hours until the use is notified that they have spam to release.

                    Could I suggest that at least 3 times per day this email can be sent?

                    Cheers

                      Thank you for your feedback. We have a clarifying question that would help us to prioritize this better: If you need notices 3 (or more) times per day, why use quarantine at all? Why not send the mails to a junk folder which the user can check on demand? If you want a notice each time any message gets quarantined, again, what prevents just sending the mails to a junk folder instead?

                    • Allow Settings for Message Expiration Timeout Interval and NDR

                      For some error codes related to sending mails, the senders may receive the NDR immediately. However, for some other error codes, the mail server marks the undeliverable messages as a temporary error and the senders doesn't immediately receive an NDR. Instead, Exchange Online repeatedly tries to deliver the message over two days. Only after two days of unsuccessful delivery attempts does the sender receive this NDR.

                      For some time critical businesses this is not acceptable. The user has to be informed very quickly (<6 hours) that his Mail was not delivered by now. Then the user can phone the recipient…

                        Keep the feedback coming. We appreciate continued details as to which option(s) would work best. The trick is balancing notifying users (who usually can’t take action, but certainly want to know when messages are delayed) vs. notifying the admins (who may or may not be able to take action but may not want such a quick notification — for example if they are responsible for a server that is down for planned maintenance or a DNS change which takes time to propagate). We would certainly like for this to be somewhat configurable in the future, but also are considering alternatives to the current 48 hours.

                        It will be better if Admins get the option to view the mail queue in Office 365. We will have more control on the email flow if this option is enabled.

                        • Prevent users from bypassing in-place hold for OneDrive for Business

                          In Place Holds in SharePoint Online use the search function to identify items that are on hold. Users have the possibility to disable search for their OneDrive for Business:
                          Select Site Settings -> Site Libraries and Lists, then select the Documents Library, select Advanced Settings, set Allow items from this document library to appear in search results = No

                          Testing shows that disabling search bypasses litigation hold allowing users to delete items without preservation.

                          Users should not be able to bypass in-place holds. A possible solution would be to prevent users from disabling search when their OneDrive is placed on…

                                • Use Outlook junk mail actions to train hosted spam filters

                                  Junkmail filtering has been a constant pain point for me with O365 business and Outlook. The spam filters have an awfully high number of false positives, and only rarely capture real spam (I don't get much on these accounts). Most of the mail that gets filtered is from the same set of senders even though I constantly tell Outlook that these messages are not Junk. O365 needs to leverage this data to improve filtering reliability.

                                    The Junk Email Reporting Add-in is our current solution for Outlook users. You can get the download for it, and learn more here:
                                    https://technet.microsoft.com/library/jj723127(v=exchg.150).aspx
                                    We do absolutely triage these submissions and use them to improve EOP.

                                    If you aren’t using Outlook, simply create a new mail to junk [AT] office365.microsoft.com and attach the entire message, including headers (see https://technet.microsoft.com/library/jj723151(v=exchg.150).aspx). We are looking at better reporting options for Mac and mobile users. What might be helpful here is commenting with which applications you use most.

                                    Administrators can also now go to http://aka.ms/FixSpam and troubleshoot their users’ most persistent spam issues.

                                    If you continue having difficulties, we recommend a support ticket to investigate current samples. It is frequently the case that a simple configuration issue is to blame — and support can help you figure this out.

                                  • Add centralized company signature with mail flow rule (in a new/reply/forward email)

                                    I think is a good idea to add company email signature at the end of the email with the mail flow rule.
                                    At the moment this thing is possible but when I reply or I forward an email, my signature appear at the end of all email not at the end of my message,

                                    • Admin Notifications for Zero Hour Auto Purge (ZAP) actions.

                                      Need to have notification to Admins when ZAP takes an action on email.
                                      1) Need to know what was found and deleted
                                      2) Even more importantly, need to know what was found and WAS NOT deleted since it had already been read.

                                      • Improve the create preservation policy wizard in the Compliance Center

                                        Adding Preservation Policies for Sharepoint and OneDrive is to time consuming. There needs to be an easier option to preserve all users drives and SharePoint Sites.

                                        The current wizard is 9 pages and you need to have the exact address of the users site to add each one. It would take months for me to add all of my users in this way.

                                        Preservation policies for Mailboxes at least let you search and select all to add them, so it would take considerably less time to complete. That would be at least a modest improvement.

                                        • Block Office Files with Macro's

                                          We are getting numerous malware attacks with zero hour Office files containing malicious Macro's, these are often blocked within 60-90 minutes but some are still being received by users. The signature is changing regularly so they aren't picked up by your scanners despite the original virus being around 12 months old.

                                          We do educate the users not to open them and Macro's are disabled, but blocking the content at the gateway would be better.

                                          Some of this functionality was available in Forefront for Exchange.
