Description

I am reporting a bug. Since upgrading to Mailcow 2024-04 on April 13th, new emails received by mailboxes are not being delivered to Outlook clients running on Android.

I have had the users completely clear their cache and stored data and gone through setting up Outlook from scratch on their clients.

The client authenticates just fine, and the mailbox contents are downloaded, but any mail received after April 13th (the day Mailcow was updated) are not delivered.

The emails however DO appear in Sogo, and using other clients such as Thunderbird on the desktop.

The issue appears to only be affecting Outlook clients on Android.

It's not a mailcow issue, we already determined that here: (sorry, it's in German...) https://community.mailcow.email/d/3510-outlook-probleme-seit-2024-04/33

Using Google Translate for you: https://community-mailcow-email.translate.goog/d/3510-outlook-probleme-seit-2024-04?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp&_x_tr_hist=true

It seems that Microsoft changed something a few days ago and that the Outlook App is doing strange things which may run at Microsoft, not in the app itself...

One user had the same problems with 2024-02, so it's not a mailcow or Sogo issue

Same here. I hope there will be a fix that we can apply to SoGo or mailcow soon...
