Hello.
We're an MSP and since around 17th/18th Jan we've had one or two users in 7 different companies (tenants) report issues with shared mailboxes or shared calendars they have access to not updating.
We've been able to get working again by simply unticking option in Outlook profile to cache shared mailboxes.
But with this amount of clients with the same issue, I've not been able to see anything regarding known M365 health / windows update issue that causes this in the last few days. Anyone else seen this issue and know root cause or have any acknowledgement of known issue

@bwilkerson217 This needs to be fixed, Microsoft. This is clearly a bad update with Office. Older versions aren't affected, unfortunately plenty of our staff are running the affected version.

Any update on this? Causing a lot of disruption for one of my customers. No mention of it on latest update on 26th Jan so i'm hesitant to switch back to cached mode just yet.

@TJMSP It's being tracked now as a service disruption.
Service Degradation for Exchange Online: EX316072 - Users' shared mailboxes aren't automatically refreshing for new email in the Outlook desktop client

Any update on a fix for this ? this is affecting a number of users at our company and is proving disruptive.

Current status: We've determined via our analysis of affected databases associated with Outlook user profiles that we don't have sufficient evidence delineating how data is actively corrupted to conclusively determine the precise source of impact. While we're continuing to determine the best methodology required to collect this diagnostic data, we've verified via internal testing and with some affected users that impacted mailboxes can effectively resolve the issue by creating new Outlook profiles for users, following the steps outlined in this document https://support.microsoft.com/en-us/office/create-an-outlook-profile-f544c1ba-3352-4b3b-be0b-8d42a54...
I'm testing this now, but I have little faith...
MS is severely underestimating this problem and its impact

Hmm this seems to apply to Microsoft Outlook desktop etc right? I'm experiencing this issue using outlook.com - I don't use the desktop software.

This is awesome good job M$!
Hardcore start to the year.
First the domain controllers (2012R2, 2016, 2019)
were killed by the epic security update causing them to reboot in circles requiring safe mode to uninstall.
Then the super update for terminal servers making them literally terminal.... Untill you uninstall it..
On 2013 office the ms upload center is crashing on launch with every single run.
Never versions can't sync shared mailboxes or Calendars.
As a bonus, some users have a never ending 'retrieving info from exchange' when they receive an image in the body of an email.
Absolutely great job on the updates in 2022 gotta love how little attention they give to any of these too.
All we have are workarounds involving mostly re-creating the users mail profile which works for a week or so untill the issue comes back.
Care to advise how should we tell users not to ask for alternative solutions for emails when all you can provide them with are mediocre workarounds with their issues returning ?
Seems the real solution is to not use Microsoft products in the first place.
Why is it always such a nightmare when you have to keep MS products updated...

@dptg-noah re-create the outlook profile of the affected users. Again a workaround. I would suggest to also flag it in your O365 admin portal. The more it gets flagged, the higher it will get pushed in the O365 engineering team.

@Jurgen Van Duvel When we tried to fix this using SARA, it created a new profile. This did not rectify the problem. I actually did report the problem on February 8th in our O365 admin portal, but the status was changed to "No issue found".
We enable "shared mailbox" functionality via mailbox delegation permissions ("Read and manage", "Send as", "Send on behalf of"). I do not know if this is technically the same exact thing as the shared mailbox discussion here, but we are seeing the same exact problem everyone here is describing and creating a new profile, disabling/reenabling cached mode, and removing/readding the mailbox delegation permissions has not resolved the problem thus far. Only keeping cached mode disabled works.

@dptg-noah look up this incident EX316072, Exchange Online,
At the moment it's flagged ad 'investigation suspended'

@gblackburn Hi, experiencing the same here for our enquiries and accounts team who share mailboxes. I haven't found a setting for turning off cached shared mailboxes only. The cache seems to be for the user's whole mailbox. Be really interested to see a fix from Microsoft.

@gblackburn We have experienging the same issue. We have created a case in Microsoft as well.
