When logging in or adding users to the Outlook client on Windows or Mac, Microsoft Outlook. Offers two distinct connection modes: Online Mode and Cache Exchange Mode.

But in order to fix problems with Outlook, users may disable cached mode in Outlook settings and switch between the Online Mode and the Cached Exchange Mode. This blog post covered the reasons and methods for disable cached mode in outlook, along with the cached Exchange Mode.
I had been accessing my shared mailboxes in Microsoft 365 using the Cached Exchange Mode for years. As far as I was concerned, everything was quick and easy. I have no idea that it would ultimately affect Outlook’s functionality and result in sending and receiving email delays, Outlook freezing, improper visibility for new emails, etc. I then understood that this mode wasn’t as ideal as it first seemed to be.
It didn’t take me long to determine that having many shared mailboxes open simultaneously under one profile was the root source of these issues, since the OST file became too huge. My file had already beyond the 50 GB recommended size limit for an OST file. I realized that something had to be done to stop any further harm from happening.
