User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:156.0) Gecko/20100101 Firefox/156.0

Steps to reproduce:

I added one EWS account and then a second one - both are on the same server.

Actual results:

Thunderbird assigned all directories and mails from account 1 to account 2. So account 2 was actually a mirror of account 1 (with the same EWS folder IDs, according to the SOAP requests/responses).

Expected results:

I had expected so see account 2's mailbox.

This happened with Tb 154, 155, 156.

I could eventually receive the correct mailbox when I

  • deleted account 2
  • deactivated account 1's automatic connections
  • deleted all Exchange cookies and the cache
  • created the account in manual mode.

I was able to reproduce this with our on-premises test server. It does not reproduce with a Microsoft 365 connected account.

STR:

  1. Add an on-premises test account using automatic configuration.
  2. Add another on-premises test account using automatic configuration.

Both accounts end up viewing the same underlying messages from the first account.

This appears intermittent.

It seems like this might have something to do with Necko caching because if you wait long enough between adding the two accounts, then the issue goes away.

Does your server use basic authentication or NTLM?

Flags: needinfo?(domi)

It's Microsoft-IIS/10.0 and can only handle basic authentication.

Flags: needinfo?(domi)

That means it's probably not Necko related then since in 156 we weren't using Necko for Basic.
