Delay in Email Synchronization from O365 to Dynamics CRM 8.0 (On-Premise) via Server-Side Sync

We are using Dynamics CRM 8.0 (On-Premise) with Server-Side Synchronization to sync emails from an O365 mailbox to a CRM Email Queue. However, we are facing frequent delays in email synchronization, causing operational inefficiencies.

Observations & Issues:

Emails are not syncing in real-time – We see delays in email synchronization from O365 to the CRM queue.
No suspicious errors in logs – Despite checking CRM logs, we haven’t found any obvious issues indicating failures.
BulkDelete job causing timeouts? – We have observed that the BulkDelete process sometimes experiences timeouts, but we are unsure whether this is impacting the Microsoft Dynamics Async Processing Service.
Manual restart of Async Processing Service helps – When we restart the Microsoft Dynamics Async Processing Service, emails start syncing immediately. This suggests that something is blocking or delaying the sync process.
High response load when emails sync together – Since emails are getting queued and arriving all at once after a restart, this increases the workload for our team, leading to delays in processing responses.
O365 Mailbox reaching storage limits – The O365 mailbox has reached 95% of its storage capacity, which we are addressing by deleting old emails and optimizing storage. However, we are unsure if this is related to the sync delay.

Request for Help:

How can we identify the exact cause of these email sync delays?
Does the BulkDelete process impact the Async Processing Service and email sync?
Are there CRM or O365 settings/logs that can help pinpoint why emails are not syncing in real-time?
Would optimizing storage in O365 resolve the issue, or should we look at CRM-side optimizations?
Any recommendations for troubleshooting or improving sync performance?

Any insights or suggestions would be greatly appreciated.
