Migrated users in a new MS Tenant have old calendar invites from previous tenant users
Good afternoon. We recently moved a group of users to a new Microsoft tenant. Before the migration, some users had sent out meeting invitations while using the old tenant. Now that they’ve transitioned to the new tenant, they were able to remove those meetings from their Outlook client. However, the attendees who received those invitations still see the meetings in their calendars I have tried to use the command "Remove-CalendarEvents" but because the original account was used to create the invites under the old tenant, the command cannot find that email address in the new tenant. Any help would be greatly appreciated.
Outlook not parsing ics invites with rrule BYMONTHDAY=-1 or BYSETPOS=-1 properly
Current Behavior When an ics event is attached or imported as a file, and the rrule contains either BYMONTHDAY=-1 or BYSETPOS=-1, it is not properly converted to the outlook/exchange meeting type and the ics attachment will read as "not supported calendar message". It is possible to work around this by appending an additional semicolon to any property in the rrule string prior to the BYMONTHDAY=-1 or BYSETPOS=-1. However, the workaround above is actually syntactically invalid. Sending .ics invites that contain an rrule with this workaround that are opened in any application other than outlook would fail to be processed. Reproduction environment MacOS Sequoia 15.3.2 (24D81). definitely doesn't matter. using outlook for mac desktop app, outlook web app Reproduction steps See the attached ics invites - note the only difference is the additional semicolon before BYMONTHDAY in the second invite. Save these as files with the .ics extension, and then open them with outlook. Invalid invite - an event that repeats monthly on the last day of the month starting on May 31st for two months.

Managing multiple shared calendars in Outlook is currently frustrating. The calendar overlay view is clunky and doesn't offer the flexibility needed to easily compare schedules. Suggested Improvements: Show side-by-side views for multiple calendars in a cleaner layout Allow color coding or highlighting conflicts Support for drag-and-drop scheduling across calendars Toggle visibility with ease instead of navigating menus
Outlook calendar invite manually set accept/decline, can it be done?
Hello All, I've never had this issue but for some reason it's become a problem. I sent out he annual Christmas get together invite in Outlook as a meeting. Didn't get a lot of responses. Followed up with a reminder email. For some reason people started approaching my desk or stopping me in the hall to TELL me they're attending. I'm not sure what the aversion to hitting the accept/decline meeting is but wondered, is there a way to mark a person as Attending a meeting manually? It doesn't warrant delegation etc. but it would help a lot with managing the process if I could track attendees in one place. Any thoughts? Thanks in advance. Andrew
User unable to manage reoccurring meeting they are the organizer of
Hello Tech Community! Hopefully someone else has dealt with this issue and has some insight into the solution. Anyways, One of our users reported that they cannot manage a reoccurring meeting they organized, since they missed one meeting. They are now seen as an "attendee". I have looked all over for resolution, coming to the conclusion that MS does not have the capability for admins to manage calendar events/meetings like this. Here is the original request the user sent: "I had created a reoccurring meeting in October and declined it one week when I wasn’t going to be available. I had accidentally cancelled the meeting from my calendar and I had to have someone re-invite me to the meeting so I could still access it since I was the host. Now I am unable to make changes to the meeting invite, it doesn’t give me the option to edit or cancel it because it’s counting me as an attendee instead of the organizer." We have checked in OWA and desktop app. Same issue. Thank you in advance to any input anyone can provide.

Outlook Group Calendars - The operation failed. An object could not be found
Hello everyone, We have an issue where a user can't use any of it's M365 group calendars in the Outlook client (for Windows) anymore. Once a new item should be created, we receive the error message from the screenshot below. The permissions are all fine, since on OWA the calendars are fully functional. What we did so far: - Recreate the mail profile in the control center - Reinstall whole Office suite (includes Outlook) - Upgrade Office suite from 32 to 64 bit Finally the mentioned error message (unfortunately in german), but I think the english translation would be "The operation failed. An object could not be found.": Maybe someone has an idea how to solve this issue? Thank you!Calendar public places location suggestions (in OWA)
Hi, Is there a way to change the Bing public places location suggestions to Google Maps? I find that Bing is absolutely terrible and cannot find many local places which Google Maps can. If there is no such option, then I'd love to develop an add-in for it, but I cannot find any mention in the add-in SDK whether it is possible to hook into that functionality and provide results from elsewhere. I would appreciate your help on this!
