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...

I am sorry if a little off topic, but this is the only place where I found people commenting that they could configure activesync in outlook for android with mailcow/sogo (in recent times). Could you share what config you use?
I managed to make activesync work in bluemail, but with outlook (android) I am confused about what to input for the config:

  • Email address: [email protected]
  • password: the password of the email
  • Server: mail.mydomain.com Do I need to provide a port?
  • Domain: I tried mydomain.com and mail.mydomain.com. Do I need to provide a port?
  • User name: I tried xxx and [email protected]

Thanks a ton!

For me it works with domain empty and user name is email. Server without port.

@pschiffe : thank you very very much. Using your instruction it worked and the account gets added.
It took a little time to sync, but emails came all good

I currently have the same problem, but only for accounts with TFA enabled.

Same here, since few weeks. Cleared ActiveSync profile in Mailcow & reset account in Outlook on Android to no avail. Update from 2024.04 to Mailcow 2024.08a hasnt resolved either. I can see the EAS login from with the App password, from an IPv6 from the US belonging to Microsoft.

Edit/update: removing and re-adding account from Outlook Android cliënt leaves empty mailbox with an Account Locked notification. Removing app password for new one doesn't solve either.

Same problem here, I've never had this problem before.

The problem is back, and for about 3 weeks now, I haven't had synchronized email on several Outlook accounts using mailcow mailboxes.

Setting up the mailbox as Exchange within the Gmail app works fine, so it seems like something related only to the Outlook app (in my case, using Android).

Well, that's the problem with the Outlook app... Microsoft does as it pleases... and all the magic happens on the Microsoft servers, not inside the app.
Outlook 365 for Windows works normally though.

Hello, there won't be a a fix as the problem is only specific for Microshit's Outlook Apps. If you still want to use them, simply do not use EAS.

Simply see 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

Short form: Microsoft removed the plain auth options in their Apps (Outlook Mobile App and new Outlook App on PC) which did not allow mailcow/SOGo to authenticate against. That's why the apps are pretty much useless with EAS now. Other Apps like Gmail/Blue Mail etc. which are EAS compatible still work like a charm.
