I'm very much aware of the license requirements for Shared Mailboxes in Exchange Online and for all Shared Mailboxes we always give licensed users access to them. If we need to login to the actual shared mailbox, we assigned them a license. This could be necessary if you also have some 3rd party application that actually need to login to the mailbox and fetch e-mail for some reason. I have recently realized that you CAN actually set a password to a Shared Mailbox. Just go to admin.microsoft.com > Users > Active Users > select the Shared Mailbox > Reset password. After this, you can login with the username/password. Of course, if you access it via portal.office.com you won't see Outlook but if you go directly to outlook.office365.com you will get access to the mailbox. Anyone know anything more about this feature? Limitations? I'm not looking to break the licensing terms, all our physical users for all our customers have their own personal accounts but there are scenarios where you have a 3rd party application accessing the mailbox for some reason.Solved722KViews3likes26CommentsRule using wildcard (or domain) for handling incoming emails
In line with the email security best practices recommended at Ignite this year, we are blocking our staff from using auto-forwarding rules in Outlook/Exchange Online. However there are valid scenarios where they need to know certain urgent emails have been delivered. We have many staff working for clients or partner companies in sensitive industries where they are not permitted to access Office 365 (or indeed any webmail service) while at work. What I want them to be able to do on their Office 365 email, account is something like: IF sender = *@importantclient.com THEN send notification to myemail@importantclient.com There are variations (perhaps include the subject line or from address in the notification, butt not the content), but that is the general idea. I can do it for fixed email addresses such as knownaccount@importantclient.com, but can't find any way for end users to do this for domains (@importantclient.com or *@importantclient.com) or other wildcards (from:managersname@*). I've tried in Outlook and Flow, but can't seem to make it work. I know it is possible with a Transport Rule, but I don't feel inclined to give my end user enough access to create these, for some strange reason.. Is this doable in O365 in any way (Outlook, Exchange, Flow, anything) in a way that normal (non-technical) users are likely to be able to handle? Thanks, Bob.317KViews0likes12CommentsShared mailbox: Use send-as, not send on behalf from Outlook 2016
Hello, We have a lot of shared mailboxes. For every shared mailbox, we create a specific security group that contains the members who should have access to that particular shared mailbox. We give full mailbox permissions and send-as permissions for that particular security group onto the shared mailbox. For example, security group A has full mailbox access and send-as permissions onto shared mailbox A. By adding users to security group A, they have full access to the shared mailbox. We create every new shared mailbox/security group combo using Powershell. That has been working flawlessly for the last years. However, for a recent new shared mailbox/security group combination, when a user that's member of the related security group wants to send an e-mail from the shared mailbox (by changing the from field in Outlook and selecting the shared mailbox from the global address list), Outlook tries to send every time 'send-on behalf'. This only happens for that newly created mailbox. I compared the output of Get-Mailbox and Get-RecipientPermission for the new problem shared mailbox and an older shared mailbox (which enable users to send mail send-as from outlook just fine) but I couldn't find any differences. For your information, that's the error we get back immediately after trying to do a send-as for the new shared mailbox: Your message did not reach some or all of the intended recipients. Subject: Test from Outlook Sent: 23/11/2017 9:27 The following recipient(s) cannot be reached: name of sending user on 23/11/2017 9:27 This message could not be sent. Try sending the message again later, or contact your network administrator. You do not have the permission to send the message on behalf of the specified user. Error is [0x80070005-0x0004dc-0x000524]. Why does Outlook always tries to do a send on behalf (what we don't want) where else for other shared mailboxes, send-as works fine? Using send-as from OWA however works just fine for the newest shared mailbox. It only seems a problem related to Outlook (tested on multiple clients that have access to the shared mailbox) and that particular new shared mailbox. Thanks in advance.Solved314KViews3likes13CommentsUsing the Outlook Booking with Me Feature
Outlook’s new Booking with Me feature is rolling out worldwide. Any user with an Exchange Online license can create a personal bookings page to allow other internal and external people to book meetings with them. It’s a nice idea and a good example of how Microsoft can use its software toolkit to create new solutions. https://office365itpros.com/2022/07/25/booking-with-me/152KViews0likes5CommentsOutlook - Certificate has been revoked
Hi all, not sure if anyone has experienced it, but we are getting tthis error multiple times a day when using outlook. It says : Outlook.office365.com Information you Exchange with this site cannot be viewed or changed by others. However, there is a problem with the sites security certificate. The security certificate for this site has been revoked, This site should not be trusted, If we dont click OK, outlook cannot send or receive emails. Sometime this window is hidden behind and therefor are not aware of it during the day. if we click view certificate, it looks legit and everything seems to be ok. If enter OWA, we get same certificate(according to thumbprint), but there is no warning or error, We have created a case with Exchange online team, but they say there are no error from their side and its internal network issue. We have cleared certificate revoke list from our DNS servers without any help. Any ideas on how to troubleshoot this further? We use Outlook 2016 with latest updates and have all mailboxes in Exchange online. I only have my archive mailbox attached to my outlook, Thanks!148KViews1like40CommentsAggregate availability from multiple calendars
I prefer to keep personal appointments on one calendar (on Outlook.com) and work appointments on my work calendar (O365 Exchange), but Exchange only seems to use my work calendar to show my availability to other people in my organization. I'd like to have a way to aggregate my availability from multiple calendar sources, the way that you can overlay multiple calendars in Outlook. It's not really a matter of me seeing all my appointments, because I can easily see everything in a consolidated view in Outlook on my desktop or mobile; it's more about letting others in my organization know when I'm free to meet. I know there is (used to be?) a "free/busy server" option in Outlook client, but I feel like this should be something that can be set on my Exchange profile, so that it doesn't matter what client I'm using. Aside from that kind of option, I guess I'd guess I might be OK with a solution that duplicates anything added to my personal calendar as a block on my work calendar or vice versa, even if it's an IFTTT-type thing. I saw a similar post that mentions some 3rd-party tools from CodeTwo and Connecting Software, but given this is just a preference of mine, I'm probably not going to spend a lot on a workaround. TLDR: Is there a better approach to showing consolidated availability than manually duplicating my appointments between calendars? Thanks!119KViews12likes30CommentsHow to Enable and Use Exchange Online’s External Email Tagging Feature
Exchange Online tenants can activate external email tagging, which causes Outlook clients (not desktop yet) to highlight messages received from external domains. The feature can replace custom implementations to mark external email, usually done with transport rules. It’s easy to implement and control, but the mail tip offering to block an external sender seems a little over the top. https://office365itpros.com/2021/03/11/exchange-online-external-email-tagging/118KViews0likes13CommentsOutlook Meeting Updates Going Directly to Deleted Items
Microsoft made in change in how meeting updates are handled and smaller updates are now going directly to the Deleted items folder. This caused people to miss important updates to agenda items. I am wondering if other people also receive complaints about this? To me it seems strange that such a setting cannot be controlled by individual Outlook settings as there are settings for this already in place. Is Microsoft considering to allow this behavior to be controlled by the Outlook/Outlook on the web settings as an improvement over the current situation?
