Notably, in 2019, Microsoft extended the folder limit for shared accounts to 5,000 due to the rapid surpassing of this threshold by users. However, the limit for primary accounts remained unchanged. Present developments suggest that an adjustment to the folder limit for primary accounts may be on the horizon.

In the interim, Microsoft has put forth two temporary solutions. The first involves a straightforward reduction of subfolders to below 500, with a recommended target of fewer than 450 for enhanced security. An alternative workaround involves maintaining all folders in a collapsed state. Furthermore, Microsoft advises users to abstain from specific online actions, explicitly mentioning activities such as "View on server" and "Click here to view more in Microsoft Exchange." The timeline for the implementation of a permanent solution to this issue remains uncertain.
