Five people at our company have a representative email address that can receive emails from each other, and each person also has a personal email address that they set up to receive emails from. Emails received at the representative email address are received in the inbox of each of the five people. However, on four PCs, only two weeks' worth of emails received at the representative email address are saved. Emails from two weeks ago are automatically deleted. They are not even in the trash. All emails received at personal email addresses, even those from two weeks ago, remain there. Also, on one PC, all emails received at the representative email address and those from two weeks ago remain there. All PCs were set up on the same day and I think they have the same settings, so I'm wondering why this is happening. I would appreciate it if you could tell me a solution. Thank you in advance.
