It means to test with a Outlook profile with single Grommunio account.
EWS - Mac / Office365
outlook for mac have no profile such like windows, i would have to remove office completely, all folders..but the bigger problem is that the sent emails are shown as unread
Excuse me for saying so, but I'm always at war with Apple over things like this.
i understand well - if there was office/outloook on gnu/linux, my apple devices would already be in the trash

Same behavior for me under outlook 16.82.1. I've created a new profile with Grommunio only.
@ak4020 You can create multiple profiles in outlook for mac - see https://support.microsoft.com/en-us/office/manage-profiles-or-identities-in-outlook-for-mac-fed2a955-74df-4a24-bef6-78a426958c4c

thank you for the quick update! i can confirm that the sent elements are now marked as read / work correctly. what does not work yet is to connect a shared calendar and make a share via outlook (outlook crashes immediately)
Yes, sent mails are now marked as read, but if I take a look on my Sent Folder via Outlook for Windows, this sent item looks strange. It is a editable item, where I can edit To-field, subject and body.
Second problem with EWS: I'm not able to open a shared mailbox. Outlook error message: You do not have permission to open this folder. In Outlook for windows I'm able to open this shared mailbox.

Shared mailboxes are not implemented yet in EWS, since there are version-dependencies accompanied by it. This track is in progress, will most likely take another bit. Please also stop cross-posting with news extras, this makes it hard to follow/maintain.
The editable item (message flag) is in progress.
