I was finally able to pull the trigger on season tickets this year. I talked to my rep, and it seems like there isnt many benefits other than being able to snag open seats next year. He talked about the Hurricane club, but looking into it, it doesn't seem worth it at all.

Anyone else know how to maximize our gameday experience on Saturdays as a Season ticket holder? We plan on tailgating on our own, but would really enjoy finding a benefit that will keep me coming back.

Looking for ideas from other M365/Exchange admins.

We have an executive assistant who manages calendars for 2 primary executives and occasionally several others. Environment is Exchange Online/M365 Apps for Enterprise.

Main symptoms:

• Calendar updates sometimes don't reach all attendees.
• Example: assistant changes meeting time/date and some attendees receive the update while others don't.
• Outlook frequently freezes.
• Attachments can take a long time to open.
• Search performance is poor.
• Deleting meetings from shared executive calendars can take 1-2+ minutes.

What we've already done:

• New PC
• Fresh Outlook profile
• New OST
• Office Online Repair
• Disabled "Download shared folders"
• Disabled "Shared Calendar Improvements"
• Removed Dell SupportAssist / Dell Core Services
• Disabled Adobe Outlook add-ins
• Repaired Adobe
• Confirmed Exchange mailbox is only ~21 GB
• Online Archive is ~18 GB
• Cached Mode set to 1 year
• No PST files attached
• User has Full Access/delegate access to executive mailboxes and resource calendars

Interesting findings:

• Old OST had grown to ~47 GB.
• Fresh OST rebuilt overnight and stabilized around ~21 GB.
• Outlook is currently connected and syncing normally.
• User still reports occasional lag when working with shared calendars.

Questions:

1. Have you seen delegate-heavy executive assistant mailboxes cause meeting update inconsistencies where some attendees receive updates and others don't?
2. Are there known issues with Shared Calendar Improvements in 2025 that would still justify disabling it?
3. For executive assistants managing multiple calendars, are you running Cached Exchange Mode or Online Mode?
4. Have you seen automapped executive mailboxes cause Outlook performance degradation even with shared folder caching disabled?
5. What Exchange/Outlook logs would you collect next to prove whether the issue is Exchange-side versus Outlook-side?

Trying to determine whether I'm chasing Outlook client behavior, delegate calendar complexity, recurring meeting corruption, or something Exchange-related.

Any ideas appreciated.
