Hi,

What is your Exchange mailbox sever current memory? It requires at least 8 GB.

So please make sure the mailbox sever memory is larger than 8 GB, or we should increase it until it meets the system requirement.

Besides, we could identify the problematic worker process in IIS manager, then recycle the app pool and check if issue persists.

could you please help me with the steps to recycle the app pool, will my users be affected while resizing the app pool

That is not so hard, just open IIS manager, click the "Application Pools", then you will see all the application pools, you could recycle the problematic app pools by clicking "recycle" on the right hand. Read the link I provided above, then you could identify the problematic one. 

The recycle time is very short, it should be fine for a production environment, if you have the concern, just do it in the non-working time.
