Purview Retention Policy to target mailboxes in a security group?
Hi. not sure if I’m just being dumb, but it seems such a basic thing. I’ve created a purview retention policy, and I want to assign it to specific mailboxes. I seem to only have the option of “all users” or manually specify individual mailboxes. No option to select security groups…? Any advice appreciated. thanks.SolvedBishopstonITFeb 12, 2025Brass Contributor39Views0likes2Comments
Allowing staff to view invitees and attendees to meetings in Room Calendars
I'm currently in the process of setting up Room finder and meeting rooms for the organisation I'm working for. I've manged to get it all pretty much done but one request I've received is to allow everyone in the organisation to see not only the meeting name and organiser which I've already achieved using \calendar -User default -AccessRights LimitedDetails but also see everyone who is invited to the meetings and if they have accepted or declined. Is this possible at all? I've been trying to find a way but seem to be hitting a dead end. Even if give people delegated access to the room resource they still can't see it. I would really appreciate hearing other peoples advice and experience on this and if it's even possible at all. Many thanksSolvedThorhulFeb 12, 2025Copper Contributor32Views0likes1CommentLimit unauthenticated mail
The standard configuration in Exchange is that anyone internally can connect to telnet and send unauthenticated e-mail to anyone inside the organization. We want to limit this so that only those applications that need to send unauthenticated mail are allowed to do this. We have Exchange 2016 hybrid and the mail flow is routed via Exchange online. The local Exchange server is only used for administration and relay. With that setup, can we just remove 'anonymous authentication' from the 'Default Frontend' connector and add a connector with the ip addresses of the applications that will be allowed to send? Or will it break the mail flow? Anyone have any tips on how to achieve this? I could create a connector that contains the IP-ranges of our empoyee networks, but that seems a bit backwards.SolvedGlyFeb 04, 2025Brass Contributor83Views0likes4Comments
Exchange Online: New-Addresslist with RecipientFilter
Hello, our client will move from OnPrem Exchange to Cloud, i just set up an hybrid connection where everything works fine so far. I wanted to migrate the custom address lists from OnPrem to Online by rebuilding them with powershell. Our client has some companies and wants address lists for every company. They all have different domains so i want to create new address lists based on the UPNs. I tested with Get-Recipient -Filter and got the results i wanted, so i just used the same filter in New-Addresslist and don't get any results...what am i missing? Get-Recipient -Filter {((RecipientTypeDetails -eq 'UserMailbox') -or (RecipientTypeDetails -eq 'MailUser') -and (UserPrincipalName -like '*contoso.com') -and (HiddenFromAddressListsEnabled -eq 'False'))} // this gets me the results i wanted New-Addresslist -Name "Contoso" -RecipientFilter {((RecipientTypeDetails -eq 'UserMailbox') -or (RecipientTypeDetails -eq 'MailUser') -and (UserPrincipalName -like '*contoso.com') -and (HiddenFromAddressListsEnabled -eq 'False'))} // this creates an empty address listSolvedJanE40Feb 03, 2025Copper Contributor55Views0likes3CommentsIphone Contacts GAL
Hello, we're migrating users from exchange onPrem to exchange online and we're looking into an issue reported. Users using Outlook on Iphone reported that they don't see all the contacts they are seeing on the outlook on PC. They only see the contacts's subset named to their users. Is there a way to have the outlook on Iphone to see the entire "all Contacts" address list ? thanks SCSolvedStefanoC66Jan 24, 2025Iron Contributor62Views0likes2CommentsSystem mailbox corrupted

CBA setup for ActiveSync on Exchange server 2019 on premise
I was setting up CBA for active sync and owa on exchange on premise 2019 following this guide https://learn.microsoft.com/en-us/exchange/plan-and-deploy/post-installation-tasks/configure-certificate-based-auth?view=exchserver-2019 It was a struggle. First, I tried to make sure OWA would work on a domain PCs with CBA. Finally, after I did optional step from the guide above, increased uploadReadAheadSize value to 49152 for owa, ecp and activesync, I started getting error on browser “too many redirects, try clearing cookies”. Clearing cookies didn’t help (private windows also didn’t help), but then I installed another browser (chrome), and owa started working accepting certificates. The browser that I was experimenting with before (edge) still not working for owa, I guess something needs to be cleaned. I understand it is not specifically edge problem, but the fact that edge has cashed some data (since I did all testings on it) that doesn’t allow to connect. I was able to connect to owa with edge on another domain computer, which was not used before. After I got owa to work on PC, I installed user certificate on iphone, and owa works there with certificate too (great!! one problem solved). However, for some reason active sync still doesn’t work with client certificate set to required on the same iphone. I assume iphone should use same certificate it uses for owa (which works), so certificate is not the problem. Without requiring client certificate ActiveSync on iphone also works, so permissions/policies shouldn’t be the problem. I’m getting error codes 403 7 64 and 403 7 5. Does anybody have any suggestions???SolvedEv4ldJan 20, 2025Copper Contributor47Views0likes1Comment
Access to Exchange Admin Centre blocked using most (but not all) URL links
Suddenly, when I try to use most of the published links to the Exchange Admin Centre, including the links on the Microsoft 365 Admin Centre, my access to the Admin Centre for Exchange is blocked. The messages vary but the most common one is "admin.exchange.microsoft.com closed the connection". All of the links for the other admin centres work just fine for me (Teams, InTune, SharePoint etc.) - it's just the Exchange Admin Centre link that are mostly problematic. Two examples of links that don't work for me: https://admin.exchange.microsoft.com/?landingpage=homepage&form=mac_sidebar https://admin.exchange.microsoft.com/#/homepage The only link I can find that still does work for me: https://admin.cloud.microsoft/exchange#/SolvedInaurukunJan 05, 2025Brass Contributor541Views1like3CommentsSharing free/busy information
