Backup: Recommeded Item Count Limits for Exchange Backup
The restore process for Exchange backup may fail when the number of items exceeds 150,000. Although there is no hard limit, we strongly recommend keeping the number of items in each backup set below this threshold to ensure reliable performance. Users are advised to create multiple backup sets if the total item count exceeds 150,000 to avoid potential issues during restore.
