Outlook is working strangely for a week now. When I try to open an inbox of a shared mailbox it just stops working. Also, depending on some options it will stay loading when starting for a good 5 or more minutes. Things I already did: Office repair, both offline and online. Office reinstallation. Executing scanpst.exe. Executing outlook in safe mode. Executing outlook /resetnavpane. Creating a new profile and start Outlook with it. Deactivate all options related to Exchange Server, even for mailboxes. I also did other things but honestly I don't really remember. Some things seem to change for the better but in the end it is not working properly as it should. I just ran out of ideas. I'm not 100% sure but I think this started happening since last update.

Hi @Joel Piqueras , In order to troubleshoot, please also help confirm the following information: What mail system are you using? Please specify the specific version. Is it possible to open the shared mailbox normally in OWA? What mode does Outlook client use? Cached or online? It is recommended that you could try removing the recipient permissions for the shared mailbox and wait some time to re-add it to see if that works.

Outlook is working strangely for a week now. When I try to open an inbox of a shared mailbox it just stops working. Also, depending on some options it will stay loading when starting for a good 5 or more minutes.

I just ran out of ideas. I'm not 100% sure but I think this started happening since last update.

Hello @Aholic Liang-MSFT ,

Sorry to my late reply. Although I could fix one of my coworker's Outlook, is not working on the other one yet. I've even reinstalled windows from scratch but it is still refusing to work properly.

Looking forward for new ideas or fixes.

Hello @Aholic Liang-MSFT ,

Thank you for answering me! According to my coworkers Outlook seems to be working better than yesterday.

I will wait for today and see if things got better tomorrow. In any case, I've already written down removing the shared mailbox permissions and will try it if necessary.

Thanks again!
