Exchange synch/profile issue

Dear community, I need help to solve a problem.
1.) I'm using Outlook classic 2016
2.) I need two mail accounts in outlook
a.) my gmail account - all good with that one
b.) my AWS Workmail account
3.) all used to work fine till I had another problem with teams integration into my calendar which I tried to fix without success. After a while I thought, that when I setup outlook from scratch that this could solve the problem - but it got worse.
4.) when I started the newly installed outlook, I can load my gmail account, and when I add my AWS Workmail account, I get the message that the account was successfully added and need to restart Outlook.
5.) After the restart I get the two messages:
- The name cannot be matched to a name in the address list.
- Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. An unexpected error has occurred.
6.) so the AWS Workmail is not loaded. I also tried to add the account manually in all different ways but without success. The integration of the AWS mail account on my Android Outlook works perfectly fine.

I dont know where the problem is and tried to get answers from AI and Microsoft Support without success. Anyone has an idea?

Many thanks, Rob

    Hey Rob,

    AWS expects EWS not EAS for email syncing, and EWS is not supported by Outlook 2016.

    Try the following I hope it helps:

    1. Navigate to Control Panel > Mail > Add (Add the gmail account first using auto setup)
    2. Give your profile a name, then select Pop or Imap
    3. Select Account Type and add your mail servers (incoming: imap.mail.<region>.awsapps.com, outgoing: smtp.mail.<region>.awsapps.com)
    4. Select More Settings > Advanced
    5. Use ports 993 for IMAP and 465 for SMTP, both with SSL encryption
    6. Select Outgoing Server, Enable both My outgoing server (SMTP) requires authentication, and Use same settings as my incoming mail server.
    7. Click Ok > Next > Finish, restart Outlook

    Hope this helps!
