Bugzilla

Hello,

Confirming this issue only as partially fixed:

- Closing and opening TB after authenticating with O365(ESW enabled) does not prompt again for credentials
- Adding a new Gmail account is set up without any issues and emails are downloaded successfully
- Subsequent restarts(or normal quit/re-open) do not prompt for authentication
- Sending/Receiving emails from the Google IMAP account works successfully
- Receiving email on the O365 account works successfully
- Sending email from the O365 account times out(stuck) in the "Copying message to Sent folder " process with the following error console:
``mail.notification: onFolderIntPropertyChanged: [Exception... "Component returned failure code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED) [nsIMsgFolder.folderURL]" nsresult: "0x80004001 (NS_ERROR_NOT_IMPLEMENTED)" location: "JS frame :: resource:///modules/MailNotificationService.sys.mjs :: onFolderIntPropertyChanged :: line 158" data: no] MailNotificationService.sys.mjs:168:17``

Tested this with the treeherder build 131.0a1(20240815220039) on Windows 11, macOS 14 and Ubuntu 24.
