Hi,

One of our customers is experiencing the same issues as described by Aus-MHCD

I raised a case with Microsoft the 365 support and their suggestion was:

Suggestion
You can try to do the following:
1. Make sure that in Account Settings-->More Settings-->Advanced Tab, the Download shared folders box is UNchecked.

2. Run Windows Update to make sure you have the latest updates for Outlook and other desktop apps for Microsoft 365.

3. Re-created the Outlook profile

I replied to Microsoft 365 support and advised that all of these steps have already been tried.

Re-creating the mail profile temporarily resolves the issue for about 1 day and then the issue re-occurs.

Several other people are reporting the same issues in this community forum:

https://community.spiceworks.com/topic/2290594-office365-group-does-not-update-in-outlook-desktop-for-one-user

I would suggest that this issue be internally escalated by Microsoft as there is clearly a bug somewhere with the Outlook Desktop Client and Office 365 Group email feature.

The only workaround for the users at the moment is to get them to use the Web Portal which is not ideal or else set the group to forward a copy to their individual inboxes.

Thanks conorc26 so much for your reply. 🙂

 

I have also raised a ticket (on March 31st) for our tenant and have not heard back from MS at all. As you said we get the same steps from the old support script and have done them multiple times for multiple users and it simply doesn't last.

 

I am very confident this is a bug with the local client version of outlook. We have the latest version of it, we have tried

  • both 32 and 64 bit
  • we have created new outlook profiles
  • we have unchecked the shared folder cache
  • we have removed the users from those groups and re-added them.
  • Happens with new groups, old groups

The one and only workaround that works so far has been have the users use Outlook Web.

So I agree, MS needs to escalate this.

    I agree Aus-MHCD.

    Definitely appears to be a bug in the Outlook Client.

    Regarding my case with Microsoft 365 support these are the resolution steps I have been provided:
    Suggestion
    You can try to do the following:
    1. Make sure that in Account Settings-->More Settings-->Advanced Tab, the Download shared folders box is UNchecked
    2. Run Windows Update to make sure you have the latest updates for Outlook and other desktop apps for Microsoft 365.
    3. Re-create the Outlook profile

    I replied to them and advised all of these steps have been tried none of these steps are a resolution and that "Recreating the mail profile only works for around 1 day"

    They responded with:

    "Regarding your issue, as per our discussion, I did run diagnostics on our end on the affected users to resolve any syncing issue, please check and monitor the issue."

    When I checked with the user's the Office 365 group emails are still not updating on their Outlook Desktop Clients.

    Microsoft have since marked my case as "resolved"

    I have asked them to re-open the case and suggested this needs to be escalated & investigated further by Microsoft as there is clearly a bug somewhere on the sync between Office 365 groups & Outlook Desktop Clients.
